25 Crucial Fixes for School Leadership Pipeline Collapse

The school leadership pipeline is not just under pressure. In many systems around the world, it is collapsing from both ends simultaneously, and most of the people responsible for fixing it are too exhausted to know where to start.


Here is what is happening. On one end, the teachers who would traditionally step up into middle and senior leadership roles are looking at the principalship and saying no. Not because they lack ambition, and not because they are indifferent to the students in their care, but because they have done the maths. They have watched their principals work 60-hour weeks. They have seen experienced school leaders burned out, threatened by community members, and held accountable for outcomes no single person could control. One teacher, a near-20-year veteran in Hawaii reflecting on whether to pursue school administration, put it plainly: the current atmosphere of distrust, the polarised political climate, and the unfavourable work-life balance make the decision almost impossible to justify.


On the other end of the pipeline, the sitting principals who were supposed to mentor and inspire the next generation of school leaders are leaving. A national survey of secondary school principals by the National Association of Secondary School Principals found that 4 in 10 principals expected to leave the profession within three years. That is not attrition. That is an exodus.


And underneath all of it is the foundational problem that feeds everything else: unsustainable workload. A 2022 survey by the EdWeek Research Center and Merrimack College found the typical teacher works a median of 54 hours per week, with less than half of that time spent on direct instruction. A 2024 RAND survey found teachers were working 53 hours per week, nine hours more than comparable working adults, while earning roughly $18,000 less in base pay. In 2025, the RAND survey showed some improvement, with teachers averaging 49 hours per week, but 62 percent still reported frequent job-related stress, compared to just 33 percent of similar working adults. When the base level of the profession is that demanding, the idea of voluntarily stepping into a role with even greater demands and accountability, for a salary differential that rarely justifies the trade, is a reasonable calculation to refuse.


The good news is that this is a solvable problem. It requires clarity about what is actually causing the collapse, and it requires action at the school, district, and system level. This blog maps 25 evidence-based approaches to rebuilding and sustaining the school leadership pipeline, organised into five categories. It draws on research from the Wallace Foundation, RAND Corporation, the OECD, and school leadership associations across Australia, the UK, and the United States.


Whether you are a superintendent, a principal, a system leader, or a teacher being quietly encouraged to consider leadership, this is the most important conversation your school is not yet having.

Why the School Leadership Pipeline Matters


Leadership is second only to classroom instruction among all in-school factors that contribute to individual student achievement. That finding, from decades of research synthesised by the Wallace Foundation, means the school leadership pipeline is not a human resources problem. It is a student outcomes problem.


When a school loses an experienced principal, it does not just lose an administrator. Research shows that schools with newly placed principals in districts with strong leadership pipelines had higher reading and math achievement than schools in districts without pipelines. The cost of principal turnover is substantial at every level. The National Association of Secondary School Principals estimates the cost to recruit, hire, prepare, mentor, and continue training a single new principal ranges from $36,850 to $303,000, with a typical urban district spending approximately $75,000 per principal. And the effects on teachers compound the problem: effective principals are a primary driver of teacher satisfaction and retention. When leadership quality declines, teacher attrition increases, making the principal's job harder, which drives more principals away, which worsens the pipeline, which produces weaker principals, which drives more teachers out. It is a self-reinforcing cycle that schools and systems must break deliberately.


The Wallace Foundation's research also found that districts with formal principal pipelines averaged eight fewer principal losses per 100 newly placed principals after three years, and the entire initiative costs less than 0.5 percent of a district's budget. The return on that investment is significant. The question is not whether rebuilding the pipeline is worth it. The question is why so few systems have done it comprehensively.

How This List Was Compiled


These 25 strategies are drawn from peer-reviewed research, major longitudinal studies by the Wallace Foundation and RAND Corporation, OECD TALIS data, findings from school leadership associations in Australia, the UK, and the United States, and evidence from specific principal pipeline programs that have demonstrated measurable outcomes. The list is intentionally international in scope because the pipeline collapse is a global phenomenon, not a uniquely American problem. Australia's principal associations are already warning that the leadership crisis will follow the teacher crisis by a decade. The UK's National Association of Head Teachers called the pipeline "at risk of collapse" in 2021. The OECD's TALIS 2024 report confirmed declining teacher involvement in school-level decision-making across multiple education systems. The strategies below are organised from the structural and systemic through to the practical and relational, because solving a systemic problem requires action at every level.


Category 1: Understand the Collapse Before You Try to Fix It


The most dangerous response to a pipeline crisis is to launch a recruitment campaign without addressing why the pipeline collapsed in the first place. The following five strategies address the foundational diagnosis.


1. Stop Calling It a Shortage. Start Calling It a Conditions Problem.


The most important reframe in the school leadership pipeline conversation is this one: there is not a shortage of people capable of leading schools. There is a shortage of people willing to lead schools under current conditions. A teacher and near-20-year veteran writing in EdSurge made the point plainly, describing the current conditions as ones where making the choice to become a principal feels like knowingly stepping into a position that could be damaging to yourself and your family. When capable, experienced professionals make that calculation and decline, the system has a conditions problem, not a talent problem.


This reframe matters because the two problems require different solutions. A talent problem sends you looking for more bodies. A conditions problem sends you redesigning the role. If systems spend money recruiting aspiring leaders without addressing the conditions that will drive them out, they are filling a leaking bucket. Audit the conditions first. Understand what experienced teachers see when they look at the principalship. Survey your middle leaders about their appetite for advancement and what is stopping them. Use that data before designing any pipeline initiative.


2. Map Where Your Pipeline Is Actually Breaking.


The pipeline has multiple points of potential failure, and the break in your system may not be where you assume it is. For some schools, the problem is that no capable teacher is willing to take on middle leadership responsibilities. For others, the middle leadership pool is healthy but no one will step into a deputy or assistant principal role. For others still, experienced deputies will not pursue the principalship because they have watched it destroy colleagues. And in a fourth category, experienced principals are leaving before they have had the opportunity to mentor the next generation.


You cannot fix all of these with a single intervention. Mapping the specific fracture point in your pipeline is the necessary first step. Look at your data: How many years does the average teacher spend in your school before moving into a head of department or middle leadership role? How long do middle leaders typically spend before pursuing assistant or deputy leadership? How many deputy principals have chosen not to apply for principalship in the last five years, and why? The answers to those questions reveal where the work is concentrated.


3. Conduct an Honest Workload Audit at Every Level.


The single most consistent finding across the global research on teacher and leader attrition is workload. Not pay, not recognition, not career development, though all of those matter. Workload. The 2025 RAND survey found that 46 percent of teachers were unable to enjoy their private life due to work demands, compared to just 13 percent of similar working adults. The NCTQ's 2025 research found that 92 percent of teachers have contracts requiring 21 to 40 hours per week but 88 percent report actually working 41 to more than 80 hours per week. The gap is filled almost entirely by administrative tasks and documentation that the contract does not account for.


A genuine workload audit looks at what teachers and leaders are actually doing with their time, not what they are contracted to do. It identifies the administrative tasks that consume professional time without contributing to teaching and learning. It asks where compliance requirements could be streamlined, and where technology could reduce documentation load. It also asks which non-teaching responsibilities currently falling on teachers and leaders could be redistributed to non-teaching support staff. Until schools and systems have a clear picture of where the hours are going, any attempt to redesign roles will be built on guesswork.


4. Understand the Risk Calculus Your Best Teachers Are Running.


Before a capable, experienced teacher declines a leadership role, they almost always run a private cost-benefit analysis. They look at the salary differential and assess whether it compensates for the additional hours, accountability, and complexity. They look at the principal in their school and ask whether that person seems happy, healthy, and in control of their professional life. They ask what the role costs in terms of family time, personal health, and private life. They assess whether the autonomy that comes with leadership is real or merely theoretical in a policy environment characterised by compliance and accountability.


In most systems, that calculation is currently coming out negative. A 2024 RAND survey found teachers desired a roughly $16,000 increase in base pay to consider their pay adequate, even before accounting for any leadership loading. Systems that want to change the pipeline need to understand and address that risk calculus directly. Conversations with middle leaders and high-potential teachers about what would make the leadership role attractive are more valuable than any recruitment campaign.


5. Acknowledge the Compounding Effect of Dual Crises.


The school leadership pipeline collapse does not exist in isolation. It sits inside a teacher shortage that is itself severe. According to 2025 data from the Learning Policy Institute, at least 411,549 teaching positions in the United States were either unfilled or filled by teachers not fully certified for their assignments, representing approximately one in eight of all teaching positions nationally. In Australia, the principal association president has already warned that the leadership crisis will follow the teacher crisis by a decade.


The two crises compound each other in a specific way. Teacher shortages make the principal's job harder. Harder jobs make principalship less attractive. Less attractive principalship produces fewer aspiring leaders. Fewer aspiring leaders means the next generation of teachers has fewer strong principals to observe, learn from, and be mentored by. Which produces even fewer aspiring leaders. Breaking this cycle requires simultaneous action on both teacher conditions and leadership conditions, not sequential action where one waits for the other to resolve.


Category 2: Fix the Structural Conditions That Repel Leaders


Understanding the collapse is necessary but insufficient. These five strategies address the structural changes that make leadership roles worth pursuing.


6. Redesign the Principalship as a Sustainable Role.


The evidence is clear: the principalship as currently designed in most school systems is not sustainable for most people. A Gallup survey cited in multiple studies found principals were working on average 62 hours per week. The role has expanded steadily over decades to incorporate responsibilities that were once distributed across specialised staff, including mental health crisis management, IT troubleshooting, compliance documentation, community relations management, curriculum development, and budget administration, all on top of instructional leadership. The result is a role so broad that it is genuinely impossible to perform well.


Sustainable role redesign requires two things. First, it requires a systematic removal of responsibilities that do not require principal-level expertise and their redistribution to appropriate support staff. Second, it requires protection of the time the principal needs to do the one thing that most determines school quality: instructional leadership. Schools that have redesigned the principalship to protect instructional leadership time, support teacher development, and build distributed leadership teams have consistently shown higher principal retention. This is not a cultural adjustment. It is a structural and resource decision that requires superintendent and system-level support.


7. Close the Compensation Gap Between Risk and Reward.


No serious discussion of the pipeline can ignore pay. Teachers who are considering leadership roles look at the differential between their current salary and a principal's salary and ask whether it is worth it. In many systems, the answer is plainly no. The RAND 2024 data found teachers already feeling their pay was inadequate by roughly $16,000 per year in base salary. A principal's salary typically represents a meaningful but not dramatic increase on a senior teacher's salary, while the hours, accountability, and personal cost increase dramatically.


Compensation reform does not have to mean simply paying principals more, though in many systems it does. It also means ensuring that middle leadership roles are compensated appropriately, so teachers are not expected to take on substantial additional responsibility for minimal or no additional pay. Where systems cannot move quickly on salary, they can consider other forms of compensation: protected planning time, reduced teaching loads for middle leaders, dedicated leadership development funding, and clear career pathway structures that show teachers what future earning looks like. The goal is to make the leadership value proposition honest and attractive, not to paper over a poor deal with mission-driven language.


8. Build Genuine Autonomy Back Into the Role.


One of the most consistent findings in the research on principal departure intentions is the erosion of professional autonomy. Almost three-quarters of respondents in the UK's NAHT 2021 study cited a lack of trust and autonomy as having become corrosive to their leadership experience. The OECD's TALIS 2024 data confirmed that teacher involvement in school-level decision-making has been declining across multiple education systems since 2018.


Principals who feel like middle managers executing centrally mandated policies rather than professional leaders making contextually informed decisions are principals who leave. Rebuilding genuine autonomy means systems making meaningful decisions about which levers of control are held centrally and which are genuinely delegated to schools. It means trusting principals to make curriculum, staffing, and community decisions within a framework of clear outcomes rather than prescriptive process compliance. Schools cannot recruit for leadership if the role comes with minimal actual authority. Autonomy is not a soft benefit. It is a structural precondition for sustainable leadership.


9. Address the Particular Vulnerability of Rural and Regional Schools.


The pipeline collapse is not distributed evenly. Rural and regional schools face acute versions of every pressure affecting urban schools, with fewer resources to respond. Smaller staff pools mean fewer internal candidates for leadership roles. Distance from universities and professional development hubs makes leadership preparation programs harder to access. Competitive salary packages are harder to offer against the tax base available. And the social isolation that can accompany rural school leadership compounds the personal cost of an already demanding role.


Rural and regional systems need specific pipeline strategies, not just scaled-down versions of urban approaches. Growing your own local leadership candidates is particularly important in contexts where outside recruitment is expensive and often unsuccessful. Collaborative leadership preparation programs across clusters of rural schools spread the resource burden. Dedicated rural leadership allowances and housing support have shown results in some jurisdictions. Peer coaching networks connecting rural principals to each other address the isolation that drives early departure. Pipeline strategies for rural schools must be designed for rural contexts, not adapted from urban ones.


10. Create the Conditions That Keep Experienced Leaders In Long Enough to Mentor.


A pipeline is only as strong as the mentors within it. If experienced principals are leaving after five to seven years because the role has become unsustainable, the pipeline loses the people who would otherwise be identifying, developing, and encouraging the next generation of leaders. The research on what keeps experienced principals is consistent: collegial relationships, genuine autonomy, meaningful professional learning, and feeling trusted and valued by the system above them.


Systems that invest in experienced principal retention as a pipeline strategy, not just as a cost reduction measure, gain a compounding return. Every experienced principal who stays another three years is a mentor who can develop one or two aspiring leaders from within their school. Retention bonuses, executive coaching for senior principals, and career pathways beyond the principal role, into leadership coaching, curriculum design, or system advisory roles, all extend the working life of experienced leaders and deepen the mentoring capacity in the pipeline.


Category 3: Build the Pipeline Infrastructure


With conditions addressed, the following five strategies address the specific programs and practices that build pipeline depth.


11. Launch a Formal Aspiring Leaders Program.


One of the most reliably effective pipeline-building investments a school or district can make is a structured aspiring leaders program. The Wallace Foundation's research on principal pipelines found that districts with comprehensive pipelines, including formal programs for identifying and developing aspiring leaders, had measurably better principal retention and student outcomes. Their analysis found that implementing a principal pipeline costs less than 0.5 percent of a typical district's budget, a remarkably low investment for an intervention with documented system-wide effects.


An aspiring leaders program is not a vague commitment to developing future leaders. It is a structured, multi-stage process that identifies high-potential classroom teachers, gives them progressively larger leadership responsibilities, connects them with mentors, provides access to formal leadership learning, and builds a clear pathway from classroom to leadership role. The Long Beach Unified School District's leadership pipeline, studied in depth by the Learning Policy Institute, models collaboration through administrator-run workshops, mentoring from practising administrators, collaborative inquiry, and participation in instructional leadership activities. The key is that the program is deliberate, documented, and staffed. Leadership development that happens by accident does not produce reliable pipeline depth.


12. Invest in Middle Leader Development as Your Primary Pipeline Infrastructure.


The middle of the pipeline is where most systems fail. The leap from classroom teacher to middle leader, whether that is head of department, year level coordinator, or instructional coach, is the first step in the leadership pathway, and it is the step most often taken without adequate preparation or support. Teachers who find the middle leadership experience unsatisfying, isolating, or unsupported rarely proceed further up the leadership pathway. Those who find it professionally rich, well supported, and meaningfully autonomous are the ones who eventually put their hand up for assistant principal and deputy roles.


Investment in middle leader development is therefore investment in the entire pipeline above it. Middle leaders need three things their schools often do not provide: dedicated time to do leadership work rather than just teach and also carry a leadership title, structured development that goes beyond one-off professional learning days, and genuine authority to make decisions within their area of responsibility. Schools that create middle leadership roles with real substance, not just additional administrative tasks with a title attached, are the schools that generate internal candidates for senior positions.


13. Build Distributed Leadership Models That Develop Leaders While Reducing Isolation.


Distributed leadership is sometimes described as a workload solution for principals. That is accurate but incomplete. Distributed leadership is also a pipeline-building strategy. When a school creates genuine distributed leadership, giving teams of teachers and middle leaders real authority over instructional decisions, professional development design, curriculum implementation, and culture initiatives, it creates a cohort of practitioners who are developing leadership experience, confidence, and identity within the safety of a supported team structure.


A Bain and Company analysis of distributed leadership in schools identified a consistent pattern: the systems that were producing the most effective future school leaders were those that had put promising educators in distributed leadership models with genuine end-to-end responsibility for teaching and learning in their context. These were not teachers who had been given administrative tasks while also carrying a full teaching load. They were teachers with real leadership scope, real accountability, and real support. The development was built into the work, not added on top of it. This approach also directly addresses the isolation problem that drives many aspiring leaders away: distributed leadership is inherently collegial.


14. Create Grow-Your-Own Programs That Build from Within.


Recruiting leaders from outside the school or district is expensive, often unsuccessful, and does nothing to build internal pipeline capacity. Grow-your-own programs deliberately identify promising teachers early, invest in their development across multiple years, and create a structured pathway from classroom to leadership role within the system that has invested in them.


The evidence for grow-your-own approaches in both teacher and leadership pipeline development is strong. The RAND 2025 analysis found that large school districts were significantly more likely to hire principals from within the district than small districts, and that hiring from within correlates with stronger principal development investment. Small and rural districts often cannot sustain a grow-your-own program in isolation. Collaborative programs across clusters of schools, or supported by district or system level infrastructure, spread the investment and increase the candidate pool. The goal is to make internal promotion the norm, not the exception, and to create the development infrastructure that makes it realistic.


15. Partner With Universities and Professional Associations on Leadership Preparation.


Most formal leadership preparation programs sit inside universities, but the research on what makes those programs effective consistently points to a gap between the academic content of the programs and the contextual realities of the schools graduates are entering. The most effective leadership preparation combines university knowledge with school-embedded experience, mentoring from practising principals, and project-based learning in real leadership contexts.


Districts that have developed university partnerships tailored to their specific community context, rather than enrolling aspiring leaders in generic educational leadership masters programs, have consistently produced better-prepared graduates who stay in leadership longer. The Wallace Foundation's 2025 research found that 75 percent of districts nationwide have some principal pipeline activities, with on-the-job support and evaluation being the most prevalent domain. The least prevalent are the pre-service preparation partnerships. A partnership with a university to co-design a leadership preparation program that is embedded in school practice, mentored by experienced local leaders, and contextualised to the community the aspiring leaders will serve is among the highest-leverage pipeline investments a district can make.


Category 4: Build the Culture and Conditions Where Leaders Choose to Stay


Pipeline infrastructure is necessary, but aspiring leaders who enter programs and then encounter toxic cultures, isolated principals, and unsupported new leader experiences will still leave. The following five strategies address the culture conditions that sustain pipelines.


16. Make the Wellbeing of School Leaders a Non-Negotiable System Priority.


The research on what drives principal departure is not complicated. Unsustainable workload, isolation, and lack of systemic support are the three most consistently cited reasons. All three are addressable. But addressing them requires that system and school leaders treat principal wellbeing as a genuine priority, not a wellness program that is launched and then quietly defunded when budgets tighten.


Principal wellbeing needs structural protection, not motivational support. That means maximum workload expectations with teeth. It means dedicated time for principals to engage in professional learning communities with each other. It means proactive principal supervision from the system level that prioritises support over compliance monitoring. And it means that when a principal signals they are struggling, the response is resourcing and relief, not a performance management conversation. Schools and systems that build these structures consistently report higher principal retention, which is the most basic and reliable pipeline indicator available.


17. Create Cultures Where Leadership Is Seen as Contribution, Not Sacrifice.


In many schools, the unspoken narrative around leadership is that it is a burden taken on by people who are willing to sacrifice themselves for the institution. That narrative, however unintentionally communicated, repels the most capable potential leaders. High-performing professionals generally want to contribute at their highest level. They do not want to be martyred. When leadership is framed implicitly as self-sacrifice, the people most suited to lead, those with strong boundaries, high self-awareness, and clear professional values, are precisely the ones who decline.


Changing this cultural narrative requires deliberate communication and role modelling. Superintendents and system leaders who visibly protect their own wellbeing, speak honestly about the demands of leadership, and celebrate the aspects of leadership that are genuinely rewarding create a different cultural signal. Principals who coach their middle leaders in sustainable leadership practice, rather than modelling exhaustion as a badge of commitment, develop a different pipeline. The culture that grows sustainable leaders is one where excellence and sustainability coexist as values, not where one is sacrificed for the other.


18. Build Psychological Safety into Leadership Team Culture.


One of the most reliable indicators of whether aspiring leaders will step up is whether the leadership team they can see is one they would want to join. A leadership team characterised by conflict, blame, and political manoeuvring is a deterrent. A leadership team characterised by trust, honest communication, and genuine collaboration is an invitation.


Research from the OECD and other bodies consistently finds that teachers who experience a collaborative, high-trust professional culture are more likely to engage in leadership activities and more willing to take on leadership responsibilities. Psychological safety, the condition in which people feel able to speak up, disagree, and take interpersonal risks without fear of punishment, is the foundation of that culture. It does not emerge by accident. It is built through deliberate leadership practice over time. Jonno White works with school leadership teams to develop the shared language, trust, and communication practices that high-performing teams require. Email jonno@consultclarity.org to discuss your school's context.

19. Close the Gender Gap in the Leadership Pipeline.


The school leadership pipeline has a well-documented gender problem that most systems are not addressing with sufficient urgency. Women represent the majority of the teaching workforce globally but are consistently underrepresented in senior leadership roles, particularly in secondary and district-level positions. A 2024 Women Leading Ed survey found that women are predominantly funnelled toward elementary school leadership and academic pathways, while men are elevated to high school principalships and district positions that include fiscal and operational roles, precisely the experience profile prioritised in superintendent search processes.


The consequence for the pipeline is that a disproportionate amount of leadership talent is being lost or underutilised because the pathway is structured around experiences that women are less often given. Schools and systems that are serious about pipeline depth must actively design and monitor career pathways for women, ensuring equitable access to high school, district, and operational leadership experience. Sponsorship, not just mentoring, is required: active advocacy by senior leaders who use their influence to create opportunities for high-potential women, not just offer advice.


20. Give Aspiring Leaders Real Leadership Experience, Not Just Leadership Titles.


One of the most counterproductive things schools do in the name of pipeline development is create leadership roles that are leadership in name only. A head of department who has a title and a few extra administrative tasks but no real authority, no protected time, and no genuine decision-making scope does not develop as a leader. They develop as an administrator. And when they look at the next step up the pathway, they either conclude that leadership is not for them, or they enter more senior roles significantly underprepared.


Real leadership experience requires real scope. It means giving middle leaders genuine authority over professional development planning for their team. It means allowing heads of department to make substantive curriculum decisions rather than implementing centrally mandated templates. It means creating structures where aspiring leaders can observe, practise, and reflect on leadership, not just assist with it. Schools that invest in giving aspiring leaders genuine experience at each stage of the pathway produce leaders who enter the principalship with confidence, clarity, and a realistic picture of what the role demands.


Category 5: Act Now as a Current Leader


The final five strategies are addressed directly to the school and system leaders reading this. The pipeline problem is systemic, but it is also personal. These strategies are the ones you can act on this term, without waiting for policy reform.


21. Have the Honest Conversation With Your Best Teachers.


The most important pipeline-building conversation a principal can have is an honest one with the three or four teachers in the school who have the potential to lead. Not a vague encouragement to consider leadership one day, but a direct, specific conversation about what they observe, what potential you see, what the pathway looks like, and what support would make the journey viable for them. Most aspiring leaders have never been told directly that someone senior sees their potential and is prepared to invest in it. That conversation alone changes the calculus for many.


This conversation must be honest about the demands of leadership as well. The evidence is clear that aspiring leaders who receive an unrealistically rosy picture of school leadership and then encounter the reality are more likely to leave early. An honest conversation that acknowledges the difficulty of the role while articulating why it is worth doing, and what support is available, is more valuable than a recruitment pitch. It is the kind of conversation Jonno White, bestselling author of Step Up or Step Out with over 10,000 copies sold globally and Certified Working Genius Facilitator, helps leadership teams build the skills to have. Email jonno@consultclarity.org to explore how this work might look in your school.


22. Protect Your Leadership Team's Capacity to Develop Others.


One of the first casualties of a stretched principal and leadership team is the time and energy available for developing others. When leaders are in permanent triage mode, responding to the immediate demands of the day, the long-horizon work of pipeline building gets displaced. And the leadership team that is too overwhelmed to mentor aspiring leaders is the leadership team that will face a pipeline crisis in three to five years.


Protecting pipeline development time requires deliberate scheduling and permission. Block time in the leadership team's calendar for mentoring conversations. Create a standing agenda item in leadership team meetings for aspiring leader development. Assign each member of the leadership team a specific aspiring leader to invest in over the year. These are not large time commitments. Even thirty minutes a fortnight of genuine leadership mentoring, consistently delivered, compounds over time into substantial pipeline depth.


23. Name Leadership Explicitly in Your School's Strategic Plan.


Leadership development is a strategic priority in very few schools' formal planning documents. It tends to be implicit: schools assume they will develop future leaders as a matter of course. But assumptions do not build pipelines. Explicit commitment does. A school that names leadership succession and aspiring leader development as a strategic priority in its plan, sets measurable goals for pipeline depth, and reports publicly on progress against those goals is a school that treats pipeline development as a real organisational responsibility rather than an afterthought.


Naming leadership development in the strategic plan has a practical benefit beyond accountability. It creates the permission structure for principals and leadership teams to invest time, money, and attention in pipeline activities. When developing future leaders is a strategic priority, it becomes easier to protect the time, fund the programs, and make the case to governing boards for the investment required. If leadership pipeline development is not in your school's strategic plan, it is probably not actually happening in any systematic way.


24. Develop Your Own Leadership Team's Culture Before It Becomes a Crisis.


The culture of the existing leadership team is one of the most powerful signals available to aspiring leaders about whether leadership is worth pursuing. A dysfunctional, conflicted, or psychologically unsafe leadership team is the most effective deterrent to pipeline growth that a school can produce. Research published in Frontiers in Social Psychology found that unresolved staff conflict in schools leads to higher teacher burnout, increased turnover, and measurable declines in school culture quality.


Investing in the health and cohesion of the existing leadership team is therefore a pipeline investment, not just a performance investment. It signals to aspiring leaders that joining this team is something worth doing. Jonno White, Certified Working Genius Facilitator and author of Step Up or Step Out with over 10,000 copies sold globally, works with school leadership teams to understand how each person contributes to the team's work, where conflict is emerging from, and how to build the communication and trust foundations that high-performing teams require. Working Genius, completed by over 1.3 million people globally, gives leadership teams shared language that transforms how they collaborate, make decisions, and resolve the interpersonal tensions that silently erode school culture.

25. Start Now. The Pipeline Is a Ten-Year Problem With a Today Decision.


The school leadership pipeline is a long-horizon problem. The actions you take this term to identify, develop, and support aspiring leaders will not produce a fully prepared principal candidate until they have spent three to seven years progressing through the pipeline. That means the crisis playing out in schools right now, the shortage of qualified candidates willing to step into leadership roles under current conditions, is the result of decisions or non-decisions made a decade ago. And the pipeline crisis of 2034 and 2035 is being determined by decisions being made now.


This does not mean the problem is abstract or deferrable. It means the opposite. The urgency is real precisely because the lead time is long. Every year a system fails to act on pipeline development is a year added to the shortage on the other end. The most important move is to start, imperfectly and incompletely, rather than to wait for the conditions to be right. Because in most systems, the conditions are never going to feel right. The work of building the pipeline and improving the conditions happen together, not sequentially.


Notable Practitioners in This Space


A number of researchers and practitioners are actively contributing to the school leadership pipeline conversation through their published work and ongoing engagement with school systems.


Ellen Goldring is a professor at Vanderbilt University's Peabody College and one of the leading researchers on principal pipelines in the United States. Her work on the Wallace Foundation's Principal Pipeline Learning Community has produced some of the most comprehensive and longitudinal evidence on what makes pipeline initiatives durable. Her 2025 paper co-authored with Mollie Rubin and Kathryn James McGraw on implementing pipeline sustainability is essential reading for system-level leaders.


Heather Schwartz and Matthew Diliberti of RAND Corporation's Education and Labor division have produced the most current national data on principal pipeline practices through the American School District Panel surveys. Their 2025 reports on principal turnover trends and pipeline practices across districts of different sizes offer directly actionable system-level intelligence.


Lisa Herring, CEO of New Leaders, brings both research and practitioner perspective to the conversation. New Leaders works specifically to develop school and district leaders who reflect the communities they serve, with a particular focus on equity and on preparing leaders for the most complex and under-resourced school contexts.


Common Mistakes to Avoid


The first and most consequential mistake is treating pipeline development as a recruitment problem rather than a retention and conditions problem. Systems that focus energy on attracting aspiring leaders without addressing the conditions that will drive them out are building on sand. The fix is always conditions first.


The second mistake is creating aspiring leader programs in isolation from role redesign. An aspiring leader who completes a rigorous preparation program, enters the principalship, and encounters the same unsustainable conditions that drove their predecessors out will leave within three years. Pipeline programs must be paired with genuine improvement in the conditions that aspiring leaders will enter.


The third mistake is confusing leadership titles with leadership development. Giving capable teachers a middle leadership title with additional administrative tasks but no real authority, protected time, or genuine decision-making scope does not develop them. It burns them out and removes them from the pipeline permanently. Authentic leadership development requires authentic leadership experience.


The fourth mistake is treating the pipeline as the principal's sole responsibility. In most schools, the principal carries the entire weight of pipeline development on top of every other demand on their role. Districts and systems that devolve pipeline responsibility entirely to individual schools while providing no infrastructure, no resources, and no professional learning support are not serious about the problem.


The fifth mistake is ignoring the gender gap and equity dimensions of the pipeline. Systems that do not actively monitor and address the underrepresentation of women in senior leadership and the underrepresentation of leaders from communities of colour are losing disproportionate amounts of pipeline talent to structural barriers rather than individual choice.


The sixth mistake is waiting until there is a principal vacancy to think about the pipeline. By then, the work that would have filled that vacancy with an internally prepared, contextually embedded candidate has not been done, and the system is dependent on external recruitment, which is expensive, often unsuccessful, and does nothing to build future capacity.


Implementation Guide: How to Act on This in the Next 90 Days


The pipeline cannot be rebuilt in 90 days. But the groundwork can be laid. Here is a practical sequence for leaders who want to move from understanding the problem to taking action.


In the first two weeks, conduct the honest internal audit. Map where your pipeline is actually breaking, using the diagnostic questions in strategy 2. Survey your middle leaders and high-potential classroom teachers about their appetite for advancement and what is stopping them. Use this data to identify the specific point of failure you need to address first.


In weeks three and four, have the direct conversations. Identify the three to four teachers in your school who have the potential to lead. Have the honest, specific conversation described in strategy 21. Do not wait until you have a formal program to offer. The conversation itself is the beginning of the pipeline investment.


In weeks five to eight, identify one structural change you have the authority to make now. It might be redesigning a middle leadership role to give it genuine scope and protected time. It might be creating a standing mentoring commitment in your own calendar. It might be beginning the process of adding leadership succession to the next iteration of your strategic plan. Pick the one action within your authority and execute it.


In weeks nine to twelve, build the case for system-level action. Use the data you gathered in the audit to make the case to your superintendent, governing board, or system leadership for pipeline investment. The Wallace Foundation evidence on cost and return is your ally here: comprehensive pipelines cost less than 0.5 percent of a district budget and produce measurable improvements in principal retention and student achievement.

Frequently Asked Questions


What is the school leadership pipeline and why does it matter?


The school leadership pipeline describes the pathway through which classroom teachers develop, progress, and ultimately take on school leadership roles including middle leadership, deputy and assistant principal positions, and the principalship. It matters because research consistently identifies school leadership as the second most significant in-school influence on student achievement after classroom instruction. When the pipeline collapses, schools cannot fill leadership positions with well-prepared candidates, which drives down instructional quality, increases teacher turnover, and destabilises school culture. The Wallace Foundation's research shows that schools with newly placed principals in districts with strong pipelines had higher reading and math achievement than comparison schools without pipelines.


Why won't experienced teachers step into leadership roles?


The most accurate answer is that many experienced teachers are making a rational calculation. The additional compensation for leadership roles is rarely proportionate to the additional hours, accountability, and personal cost. The 2025 RAND survey found that teachers already working nine hours per week more than comparable working adults feel their pay is inadequate by roughly $16,000 per year in base salary, before any leadership loading. Watching sitting principals struggle with an expanded role that has grown far beyond its original scope, under heightened community and political pressure, makes the calculation even less attractive. As one veteran teacher put it in EdSurge: there is not a shortage of people capable of leading, there is a shortage of people willing to lead under current conditions.


How long does it take to rebuild a school leadership pipeline?


A pipeline is a ten-year investment. Identifying a high-potential classroom teacher, developing them through middle leadership, supporting them through a deputy or assistant principal role, preparing them for principalship, and then sustaining them in that role long enough to become a mentor for the next cohort takes approximately a decade of consistent investment. Systems that do not begin pipeline work now will face an even more acute shortage in 2034 and 2035. Starting imperfectly today is better than waiting for perfect conditions.


What does a principal pipeline program actually look like in practice?


A comprehensive principal pipeline program, as defined by the Wallace Foundation and studied in detail by RAND, typically includes revised leadership standards and job descriptions, university or college partnerships for leadership preparation, clear progression pathways from teacher to assistant principal to principal, on-the-job mentoring and coaching for aspiring and new leaders, revised approaches to principal supervision, and evaluation systems aligned to leadership standards. Research shows they cost less than 0.5 percent of a district's budget and produce measurable improvements in both principal retention and student achievement.


What can a single school do about a system-level problem?


Quite a lot. A single school can conduct an honest workload audit, have direct conversations with high-potential teachers about the leadership pathway, redesign middle leadership roles to give them genuine scope and protected time, build psychological safety in the existing leadership team, and add leadership succession to its strategic plan. None of these require system-level change to begin. They require a principal and leadership team who have decided the pipeline is their responsibility to build.


Can I hire someone to help rebuild my school's leadership culture and pipeline?


Yes. Many schools engage external facilitators to accelerate the culture and leadership development work that pipeline building requires.

Final Thoughts


The school leadership pipeline collapse is not a mystery. It is the predictable consequence of decades of role expansion, accountability escalation, and workload intensification, compounded by a teacher shortage that has put the entire system under unprecedented stress. The people who would have become tomorrow's principals are watching today's principals and deciding it is not worth it. That is a rational response to what they are observing. It is also a catastrophic one for the students, teachers, and communities that depend on strong school leadership.


But pipelines can be rebuilt. The evidence is clear on what works: redesigning the principalship as a sustainable role, compensating leadership appropriately, building genuine autonomy into the role, developing middle leaders as pipeline infrastructure, creating formal aspiring leader programs, and building the team culture and psychological safety that make leadership worth pursuing. None of these require waiting for a policy revolution. Many can begin this term, in your school, with your team, using your authority.

The question is not whether your school can afford to invest in pipeline development. The question is whether your school and your students can afford another five years without it.
