A head of school transition is never just a personnel change. It is a moment that can shape a school’s culture, confidence, and strategic direction for years to come. And increasingly, those moments are arriving sooner than expected. NAIS has observed that the average tenure of a head of school has dropped by nearly a year, a shift driven largely by unexpected departures in the first three years of headship. Importantly, these unexpected disruptions often disproportionally affect female heads of school and heads of color. For schools, the unexpected departure of a head of school can mean lost momentum, strained trust, financial uncertainty, and a community left trying to regain its footing.
That pattern is what led NAIS to launch the Leadership Alignment Project (LAP) in 2025. This grant-funded effort is designed to help independent schools reduce head turnover by building a more complete set of research, tools, and programming related to leadership transitions. But the project’s work is not only about helping heads stay in place longer, it’s about helping to strengthen the relationships and practices that make leadership sustainable. It’s also about helping boards, heads, and leadership teams set clearer expectations, prepare more deliberately before a transition begins, and use data, strategy, and good governance practices to support a healthier transition.
The work LAP is doing, however, is not only for schools starting a search or already in the middle of one. It’s for any school asking how to be more aligned across its leadership ecosystem and future-ready whether a leadership transition is imminent or years away.
Early Lessons: Making and Sustaining the Right Match
In the project’s first phase, we interviewed dozens of sitting and former heads of school about their experiences in hiring, in the early phase of their headships, and in many cases about how their tenure ended. What we heard throughout the calls and focus groups didn’t surprise us as much as it put an even finer point on a critical understanding: Schools invest enormously in selecting leaders. However, they invest far less in ensuring those leaders are the right cultural match—and even less in positioning them for optimal success once they arrive.
Our early findings from these conversations reveal patterns that should give every board chair, search committee, and aspiring head pause.
Transitions are often under-resourced. Schools may spend months, sometimes years, on the search itself, only to give far less attention to the onboarding process and support that follow. As many have noted, the transition doesn’t take a year or a decision, it can take much longer. “It’s not just over because you’ve signed your contract, right? It’s truly just begun.”
Culture matters as much as competence. Heads rarely struggle because they lack the basic skills to lead. More often, they are learning to navigate unspoken norms, longstanding assumptions, and informal power structures that no résumé or search process can fully reveal.
Board-head alignment is one of the most fragile areas. Across our conversations, role confusion, uneven communication, and uncertainty about where governance ends and management begins emerged as recurring points of strain.
The job has outpaced the preparation pipeline. Heads described a role shaped by overwhelming scope, political complexity, and entrepreneurial pressure—demands that no leadership preparation program can fully anticipate or deliver on.
Transitions themselves can unsettle a school’s culture. When schools experience repeated head turnover, the resulting anxiety in the community, lost momentum, and what one head described as “learned helplessness” can compound. Meaning, after enough leadership turnover, people can begin to believe that investing in the next leader, initiative, or change effort is not worth it because it, too, will probably disappear.
Uneven support can deepen inequity. The transition model that may serve experienced, well-networked leaders reasonably well does not always translate equitably for women and heads of color. When transition supports are thin, and new heads are left to figure things out on their own, the risks they face can grow—and those risks are not distributed evenly. Within that critical first year, a new head can inadvertently step into potholes they don’t see coming, and without guidance they can step into more than one seemingly simultaneously.
Succession planning is too reactive. Many schools do not begin planning in earnest until a departure is imminent, leaving little time to build continuity or prepare internal talent pipelines.
One their own, each of these findings is concerning, but together they point to the same larger lesson that every school should take seriously: Successful transitions depend not only on who is hired, but on what the school is prepared to do next.
A Framework for What Comes Next
These findings are pointing us toward creating something more ambitious than a checklist of "transition best practices” and related resources. Ultimately, we are working to articulate and build support around a framework for an integrated leadership ecosystem—one held together by the head of school, the board, and the senior leadership team. It’s built on six interlocking puzzle pieces, each with nested components designed to address the very fragilities our early work is surfacing.
Succession planning: Help schools shift from reactive to systemic by developing emergency succession protocols, internal talent pipelines, board-level continuity plans, and more intentional attention to equity in who is developed and considered.
Alignment practice: Create repeatable habits that keep heads and boards rowing in the same direction, including role-clarity tools, shared goal-setting rhythms, and structured check-ins that surface drift before it becomes dysfunction.
Strategic trust: Build the connective tissue between the board and the head through transparency, candid conversations, healthy conflict, and psychological safety that allow difficult truths to surface early before they become larger problems.
Effective governance: Support boards in distinguishing governance from management through board chair development, thoughtful committee design, meaningful trustee onboarding, and clearer protocols for the gray areas heads consistently named.
Distributed leadership: Strengthen leadership teams, clarify decision-making authority, and create the cultural conditions for senior teams to genuinely share responsibility rather than simply absorb additional tasks. No head can carry the weight of the modern role alone.
Landscape and data literacy: Increase the capacity of heads and boards to read the environment honestly, including enrollment, financial, and cultural data fluency so that strategic decisions rest on a shared and accurate picture of reality.
The puzzle metaphor is intentional. Each piece has value on its own, but the real strength comes from the way the pieces connect—and from whether all three constituencies see the work as shared rather than as someone else’s responsibility.
Questions Worth Asking
These early findings raise as many questions as they answer––for schools, boards, search committees, and aspiring heads as well as for NAIS. A few seem especially worth asking now, as we will be doing as we move into our next phase of the Leadership Alignment Project:
If roughly one in five heads leaves within three years, what does that suggest about the match between candidates and institutions—and about the search processes that produced those matches? Whose voices are still missing from the conversation about headship?
If culture plays such a significant role in whether a transition succeeds, why do selection processes still tend to emphasize résumés more than cultural fluency on both sides of the table?
If board-head alignment is the critical piece, are we investing in governance excellence and strategic trust with the same seriousness as head development?
What are schools willing to do differently knowing that underrepresented heads may carry a heavier load through every phase of transition? Is using the same process for everyone actually equitable—or does equity require more tailored support?
And perhaps most importantly: If schools over-invest in selection and under-invest in fit and success, what are they really optimizing for? A clean announcement? A celebratory board vote? Or a head who is still leading—and still thriving—five years in?
A Field-Level Invitation
These mid-project findings are not a final verdict—they are an invitation to our wider membership reading this now. They suggest that the next frontier in independent school leadership is not to merely bring in better candidates or better search firms or to create better leadership programs in isolation. It is to create a more honest and intentional hiring and transition ecosystem—one that treats leadership continuity as a system, not a moment, and recognizes that future-ready schools need interconnected planning, governance, and support long before a transition begins.
