For the past several years, teachers have been leaving the classroom at an alarming rate. The COVID-19 era exacerbated existing fractures, and today the entire system strains under persistent teacher shortages, struggling with both teacher retention and recruitment. While some school districts appear to be getting it right by focusing on mental health and finding ways to give teachers more time to work their magic, others are trying to trudge ahead as if nothing is wrong.
This is not okay for anyone involved in public education.
The Scope of the Crisis
Teacher shortages affect at least 1 in 8 teaching positions nationwide. According to the Learning Policy Institute, roughly 425,000 positions are either unfilled or staffed by teachers not fully certified for their assignments. All 50 states plus the District of Columbia employed an estimated 387,843 teachers who were not fully certified, while 29 states reported 37,569 unfilled positions. Teacher attrition comprises about 90% of annual new teacher demand, with nearly 3 in 4 teachers who left the profession doing so voluntarily for reasons other than retirement.
The consequences are severe. Students of color and those from lower-income backgrounds are disproportionately impacted, as high turnover rates in schools serving these populations run 35% to 37% higher than in schools with the smallest concentrations of such students. When teacher shortages persist, districts respond by hiring underprepared teachers, increasing class sizes, canceling courses, and adding responsibilities to existing staff, all of which undermine student achievement.
Why Teacher Retention and Recruitment Have Struggled
The teacher pipeline has been declining for decades, and compensation gaps are a primary driver. Interest in teaching among college students has fallen to its lowest level in 50 years, and enrollment in teacher preparation programs dropped sharply by about 100,000 candidates between 2012-13 and 2014-15. Meanwhile, the teaching profession faces a compensation crisis: teachers earn about 27% less than other professionals with similar education levels, and six in 10 have taken out student loans.
But teacher burnout is not solely about pay. One principal recently explained the frustration many feel: “We had a teacher leave this year, and we were given the opportunity to provide input on who we would like to see replace them. The superintendent, with no explanation, didn’t even follow one of our recommendations. He just picked someone he knew from his past. I fought it as best I could, but in just another slap in the face to us, my input was cast aside.”
This disconnect between school leaders and building-level administrators is a key factor driving teacher attrition. The National Education Association has emphasized that collecting teacher shortage data is essential to understanding workforce needs and directing financial incentives like the TEACH Grant program toward high-need schools and shortage fields.
The Tennessee Case Study
Tennessee lost 10.36% of its teacher workforce between the 2023-24 and 2024-25 school years, the largest percentage decline in the nation. The state shed more than 7,400 educators, and nearly 2,200 vacant positions are currently listed statewide. Experts point to working conditions as a major factor. “Teachers don’t leave on pay alone,” said JC Bowman of Professional Educators of Tennessee. “It’s the working conditions, the behavior of students that are creeping in. It’s just gotten out of control.”
Key Reasons for High Turnover
Workload and Accountability Pressures
Teacher workload has expanded far beyond classroom instruction. Teachers work longer hours not only because they must be at school for extended periods, but because additional responsibilities outside the classroom have multiplied. Many certified teachers are now solely responsible for testing students and analyzing results to determine pass or fail based on state or federal mandates. New certification areas and reporting requirements continue to expand the teacher workload.
Many early career teachers enter classrooms underprepared and leave within a few years. As ETS notes, licensure assessments have historically missed the broader skills today’s classrooms demand, such as high-leverage instructional practices and AI readiness. When new teachers lack essential day-one skills, retention challenges intensify.
Mental Health and School Safety
Mental health issues among both students and teachers have created a school environment on edge, often with little to no resources. Teacher burnout is not merely an individual phenomenon but a “socially and structurally embedded issue” driven by excessive workload, performative accountability, and systemic pressures. School safety concerns, from cyberbullying to classroom disruption, compound these challenges.
Teachers today also face unprecedented, normalized political pressure. They receive death threats from parents who disagree with them, while students are almost recruited to be anti-teacher activists due to false narratives. This kind of hostility has become so commonplace that it barely receives media attention anymore.
What Works: Evidence-Based Strategies
Strong Induction and Mentorship Programs
Teachers who receive strong mentorship and induction support in their first years are far more likely to remain in the profession. The Learning Policy Institute recommends expanding access to high-quality preparation programs anchored in well-supervised clinical experiences, combined with competitive compensation and leadership roles for experienced educators.
Peer cohort models are gaining traction. Rather than relying on a single mentor, new teachers benefit from support networks at similar career stages. As one teacher put it: “I wish I had somebody there that truly understands what I’m going through…and doesn’t just tell me why, but says, ‘let’s figure out together.'”
Financial Incentives That Target Effectiveness
Performance-based financial incentives in hard-to-staff schools produce dramatic student achievement gains, but only when sustained. A landmark study in the American Economic Journal: Economic Policy evaluated a grant program offering substantial performance-based compensation to highly effective teachers in the lowest-achieving schools. The program led to dramatic student achievement improvements, nearly closing the gap between targeted schools and the district average. When the program was reversed, effective teachers departed at high rates, and achievement immediately declined.
Financial incentives work, but only when sustained and targeted to best practices in hard-to-staff schools.
Building a Diverse Teacher Pipeline
North Carolina has taken legislative action to address teacher pipeline gaps through a grant program supporting strategic partnerships. The program requires collaboration between school districts, higher education institutions, and community organizations, with strategies including paid clinical learning experiences, induction and mentoring programs, and support for bilingual education candidates.
Such initiatives recognize that equitable access to excellent educators requires intentional recruitment of top talent from all communities.
Addressing Working Conditions
A retention strategy cannot succeed without improving daily working conditions. This means:
- Reducing class sizes where possible
- Providing administrative support rather than bureaucratic obstruction
- Ensuring school safety through evidence-based discipline policies
- Creating a clear vision and school culture that values staff members
As Beyond100K reports, “belonging” has emerged as a non-negotiable retention driver. When teachers feel connected to their school community and see a pathway for growth, they stay.
What Can Teachers Do?
Teachers seeking to stay in the profession should seek induction support, build peer networks, and advocate collectively for better working conditions. If you are a licensed educator considering leaving the profession, or an administrator trying to find a way forward, the path requires collective action. Educational leaders must work with policy makers to secure support for professional development and decision-making process reforms that give teachers agency.
School boards and state board of education officials should prioritize policy changes that reduce unnecessary teacher workload, expand mentorship programs, and ensure equitable access to excellent education for all students.
For new teachers, seeking out induction program support and building peer networks is essential. For early childhood education and special education teachers, who face particularly acute retention challenges, advocating for financial incentives and reduced caseloads should be a priority.
What Can School Administrators Do?
District leaders and school leaders hold significant power to improve retention rates through listening, mentorship investment, and resource advocacy. The good news is that some strategies show immediate results:
- Listen first. Teachers are leaving for identifiable reasons. Conduct exit interviews, act on feedback, and stop making unilateral decisions about educator recruitment.
- Invest in mentorship programs. Pair new teachers with effective mentors, compensate mentors fairly, and structure support across the first three years.
- Create leadership roles. Great teachers often leave because they see no advancement without leaving the classroom. Hybrid roles that allow great educators to mentor peers while teaching offer a path forward.
- Advocate for resources. Work with policymakers to secure funding for professional development, mental health support, and school safety measures.
The Path Forward
The number of teachers leaving the profession is not inevitable. It is a policy choice. States that have invested in teacher preparation programs, competitive compensation, and supportive working conditions are seeing progress. California’s recent preliminary credentials increased 40% from 2022-23 to 2024-25 after targeted state investments, though most programs remain funded on a one-time basis and will expire without continued support.
The ongoing challenge requires sustained attention from everyone involved in public education. We cannot keep doing what we’re doing while expecting different results. The following question should guide every decision: What must teachers know and be able to do to support children’s learning, participation, and flourishing, and what conditions must be in place for them to stay?
I don’t have all the answers…but if we don’t take the time to voice our concerns, collaborate across school systems, and demand better from our educational leaders, the crisis will deepen. Tomorrow’s teaching staff depends on the choices we make today.
What is the actual cost of teacher turnover to school districts?
Replacing a teacher costs districts between $9,000 and $21,000 per departing educator, depending on location and subject area. These costs include recruitment advertising, hiring incentives, administrative processing, and the reduced productivity of new teachers during their first years. For a district losing 100 teachers annually, that translates to $900,000 to $2.1 million in direct replacement costs. Indirect costs are harder to quantify but equally significant: disrupted student learning, lost institutional knowledge, and the strain placed on remaining staff who absorb additional duties during vacancies. High-poverty districts, which experience the highest turnover rates, bear a disproportionate share of these costs while having the fewest resources to absorb them.
How can teachers advocate for better working conditions without risking their jobs?
Collective action through unions and professional associations offers the most protected pathway for advocacy. Teachers in right-to-work states may have fewer formal protections, but informal strategies remain effective: document workload issues with specific examples, present data to school boards during public comment periods, and build coalitions with parents and community organizations who share concerns about school quality. Social media has become a powerful tool for teachers to share experiences anonymously through accounts like Reddit’s r/teachers or private Facebook groups, creating pressure for change without individual risk. The key is shifting the narrative from “complaining” to “problem-solving” by arriving with proposed solutions rather than just grievances.
What are alternative certification pathways, and do they help or hurt retention?
Alternative certification programs, such as Teach For America and district-run residency models, can improve recruitment but often struggle with retention. These programs typically compress training into weeks rather than years, placing candidates in classrooms faster than traditional preparation programs. While this addresses immediate shortages, research shows that alternatively certified teachers leave the profession at higher rates than those from traditional programs, particularly in the first three years. However, residency models that pair alternative certification with intensive mentorship and gradual release of responsibility show much stronger retention outcomes. The distinction matters: quick entry without support leads to quick exit, while structured alternatives with embedded support can build lasting careers.
How does teacher turnover affect the teachers who stay?
Teachers who remain in high-turnover schools experience increased stress, expanded workloads, and declining morale, creating a vicious cycle that accelerates further departures. When colleagues leave, remaining teachers often absorb additional classes, cover absent colleagues during planning periods, and take on mentoring duties for a rotating cast of new hires. This additional burden compounds the burnout that drove their colleagues away in the first place. Research on “turnover contagion” shows that teachers are more likely to leave when they see peers leaving, particularly if those peers are high performers. The result is a school culture where instability becomes self-perpetuating, making it increasingly difficult to rebuild a stable, experienced staff.
What role do working conditions play compared to salary in teachers’ decisions to leave?
Working conditions consistently outweigh salary in teachers’ decisions to leave, though the two are deeply interconnected. Surveys of departing teachers routinely find that factors like administrative support, student behavior, workload, and autonomy matter more than pay. However, salary becomes a threshold issue: when compensation falls too far below what teachers could earn elsewhere, no amount of supportive administration can retain them. The most effective retention strategies address both simultaneously. A school with excellent leadership but poverty-level wages will lose teachers to higher-paying districts. A district with competitive salaries but toxic administrators will lose teachers to schools with better cultures. The sweet spot combines livable compensation with the working conditions that make teaching sustainable.
