State data shows that teacher turnover (the share of educators who don’t return to the same district) has climbed to roughly 20% in Texas over the past two years, up from about 16% pre-pandemic.
In the 2022–2023 school year, Texas hit a new high with a 21.4% turnover rate – an 81% increase since 2010. This trend spans all K-12 school types. Charter schools, in particular, face an even heavier churn, with roughly double the teacher turnover rates of traditional public districts. While private schools are not required to report turnover publicly, many also struggle to retain talent in the face of rising competition and workloads.
These data points mirror a troubling trend across Texas: A surging teacher turnover crisis that is steeply costing schools, students and communities.
Houston’s exodus in focus
No place illustrates the problem quite like Houston ISD. Following a contentious state takeover of the district in 2023, HISD saw an exodus of educators. By the summer of 2024, roughly 4,700 of HISD’s 11,000 teachers had left during the 2023-24 school year, or over 40% of the entire teaching force gone in one year.
June alone brought more than 2,400 teacher departures, a record number. Many educators pointed to the drastic reforms implemented by state-appointed Superintendent Mike Miles, including reassignments and a rigid new “New Education System” (NES) model, as a key reason for leaving. Miles and his team have been blunt about their philosophy: If teachers don’t embrace the new high-pressure culture, they are free to go. Two-thirds of the teachers who quit HISD mid-year were from the stringent NES campuses.
While Miles argues this turnover will ultimately weed out low performers and elevate instruction, the immediate disruption is undeniable.
What does this teacher exodus cost?
Replacing teachers is expensive. Recruiting, hiring and training a single new teacher can cost districts tens of thousands of dollars in staff time and resources. Research by the Learning Policy Institute finds that large districts spend nearly $25,000 on average to replace a departing teacher when you factor in separation costs, recruiting, hiring and onboarding.
Even in smaller districts, estimates run about $9,000-$21,000 per teacher in turnover costs. Now multiply those figures by the volume of Texas’s departures. The recent 4 percentage-point rise in the state’s turnover rate translates to roughly 15,000 additional teachers not returning each year. By some estimates, Texas districts collectively lose hundreds of millions of dollars annually to the churn of teachers.
In Houston ISD alone, the implied price tag of replacing 4,700 teachers in one year could add up, and that is money that could have been spent on students rather than on constant rehiring and training. This financial drain hits the state level too, as Texas must invest in new teacher preparation, certification subsidies and emergency hiring programs to backfill the loss of experienced educators.
Classroom consequences for broader community impacts
The most devastating cost of teacher turnover, however, is borne by students. High turnover disrupts learning and undermines achievement. Research consistently shows that first-year and under-prepared teachers have a less positive impact on student outcomes than veteran, certified teachers.
Research reported by The Learning Policy Institute and others shows that the achievement gap that students of color, low-income students and students with disabilities tragically experience is in large part due to inequitable access to qualified teachers. Thus, Black and Brown students feel the brunt of the negatives associated with high teacher turnover.
Yet, Texas schools have increasingly had to rely on underqualified staff. Over one-third of newly hired Texas teachers in 2023-24 were uncertified, almost double the share from just two years prior. These newcomers, while often dedicated, are more likely to leave themselves, creating a vicious cycle.
Crucially, these harms hit hardest in already disadvantaged communities. Schools with higher poverty rates and lower performance often suffer the highest turnover, as seen in Houston where districts like Spring ISD, Sheldon ISD and inner-city HISD have recent turnover rates above 20%, roughly double those of more stable districts like Galena Park ISD and Pasadena ISD (12%).
That instability further entrenches educational inequities. As one analysis noted, over half of departing teachers in some Houston-area districts left the public school system entirely.
Beyond dollars and test scores, high teacher turnover inflicts damage on the social fabric of schools and communities. When a beloved teacher walks away, students lose an adult role model and source of stability. Parents lose a trusted partner in their child’s education. Over time, a revolving door of educators erodes parents’ confidence in the school and dampens community engagement.
Losing these community linchpins affects local cohesion and pride in the school system. Addressing this crisis will require more than emergency measures; it demands a commitment to treating teachers as the invaluable assets they are.
