This study investigates the influence of principal tenure on the retention rates of the teachers they hire over time. We analyzed the hiring practices and teacher retention rates of 11,717 Texas principals from 1999 to 2017 employing both individual and year fixed effects. Main findings indicate that a principal who stays in the same school for at least three years begins to hire teachers who stay to both three- and five-year benchmarks at increasingly higher rates. However, the average Texas principal leaves a school after four years and while we do find small positive gains in the initial retention rates of teachers at the next school, the majority of principal improvement in teacher retention does not appear to be portable.
