A FOLIO COLLABORATIVE RESEARCH BRIEF

The State of Faculty Growth in Independent Schools

WHY WE'RE PUBLISHING THIS

Even schools doing everything right are watching great teachers walk out the door.

At Folio, we spend our days talking with school heads, academic leaders, and teachers across the country about what it really takes to build a growth-centered culture. We know firsthand how teacher turnover ripples through a school's community and student experience, but what does the data say? We gathered the latest national research, layered in what we’re hearing from our own member schools, and brought it all together here. This work gets to the heart of why we do what we do as a nonprofit.

THE INDEPENDENT SCHOOL PICTURE

What's Different in Independent Schools

1 in 3

Educators who see a clear path to advance

(SAIS, 2026)

9 in 10

Educators who want more learning and growth opportunities

(SAIS, 2026)

58%

Heads of School reporting fewer applicants than the year before

(NAIS, 2023)

41%

Heads of School saying candidate quality had gotten worse

(NAIS, 2023)

The most recent sector data comes from the 2026 SAIS study, Designed to Last: Reimagining the Employee Value Proposition in Independent Schools, which surveyed 1,558 educators across member schools. The core finding: while independent school educators share a deep sense of purpose, three structural vulnerabilities undermine it:

Workload: Only 63% find their workload manageable.

Compensation: Only 45.7% consider their pay competitive.

Career Growth: Just 33.8% see a clear path for advancement, despite 89.3% desiring more professional learning opportunities.

This career growth gap is particularly critical. Independent schools are attracting the kind of ambitious, growth-minded educators every school wants. What's missing isn't the desire to grow. It's a visible way to do it without leaving the classroom or the community that drew them there in the first place.

The hiring landscape across independent schools has been undeniably tough. NAIS data from recent years shows that nearly six in ten heads of school saw a drop in applicant numbers, while four in ten noticed a decline in candidate quality.

But if you look beneath the surface, the real challenge isn't just about finding great teachers; it’s about keeping them. NAIS research on why educators choose independent schools reveals that teachers aren't leaving because they’ve lost their passion or purpose. Instead, they leave when the reality of the job doesn't align with what they were promised. Barely half of teachers felt their hiring process set realistic expectations, and less than half felt truly supported by leadership once they arrived. Combine that disconnect with the daily fatigue of doing more with less, and it becomes clear that schools can't recruit their way out of a retention problem.

THE CHARGING STATION EFFECT

The Impact of Leadership on Retention

81%

Teachers who view professional development as one of the most meaningful forms of recognition

(NAIS, 2025)

77%

Teachers who view a personal note from a supervisor as one of the most meaningful forms of recognition

(NAIS, 2025)

47%

Teachers satisfied with the support they get from school leaders

(NAIS, 2021)

When Vanderbilt’s Peabody College partnered with NAIS on their 2025 Faculty Survey, the data revealed a stark reality: only 15% of faculty feel consistently recognized, while 40% rarely or never feel appreciated at work. Only 21.7% believed their school had a real culture of recognition. As the researchers described it, without an intentional system, "the battery that powers commitment, morale, and belonging steadily drains."

This report frames school leadership as a charging station, and the data backs that up. Leadership support was the single strongest predictor of teacher morale and retention that the study found. Teachers report high satisfaction with the impact they have on students directly. What's lower, consistently, is their satisfaction with the growth-oriented feedback and support they get from school leaders. The gap between those two numbers is where turnover risk lives.

THE WIDER BACKDROP

What's Happening to Teachers Nationally

Public schools with 2+ unfilled vacancies

(NCES, 2024)

Independent schools aren't feeling the strain in a vacuum. What we're seeing inside our communities is part of a much larger, nationwide story. According to RAND’s State of the American Teacher Survey, over half of all K-12 teachers (53%) are actively struggling with burnout, spending roughly 10 hours beyond their contractual obligations each week to manage classroom behaviors, lesson prep, and administrative demands.

Recent data also shows that 55% of teachers face frequent job stress, a stark contrast to the 34% reported by other college-educated professionals. And as teachers contemplate leaving the field, the pipeline behind them is running thin. The National Center for Education Statistics found that nearly three-quarters of public schools started the school year with multiple unfilled teaching roles. The big-picture data confirms this challenge is systemic, and supporting teachers has never been more important.

What the Research Says Actually Helps

This is the part we find most hopeful. The research isn't vague about what helps. SAIS's recommendations point directly to protecting educators' time and showing teachers how they can grow without leaving the classroom. The researchers behind the Vanderbilt University and NAIS report found that independent school teachers ranked professional development, stipends, and protected planning time as the most meaningful forms of recognition, well above symbolic gestures.

This echoes everything our member schools share with us. Educators stay when they feel celebrated, cared for, and given space to collaborate. We have also written about how focusing on five core building blocks (dedicated time, real feedback, supportive leadership, a shared instructional vision, and separate tracks for growth versus evaluation) schools can shift from simply managing instruction to cultivating a true learning culture.

Putting these principles into practice requires intention and a system built to support implementation. That's where Folio comes in. Let us partner with you to start building better pathways for growth.

What Strong Schools Are Doing Differently

We see this play out at schools we work with every day.
