Abstract
Prior research finds that some high-quality preschool programs are successful in generating significant initial academic gains and long-term benefits for students as they progress through school. This study examines one of the mechanisms through which North Carolina's statewide pre-K program (NC Pre-K) may generate such benefits: improvements in the teaching environments of the elementary schools in which NC Pre-K graduates enroll. We find that an increased presence of former NC Pre-K students in elementary schools over the period 2004-2018 was associated with better teachers' perceptions of different dimensions of their teaching environment, as well as increased teacher and principal retention. Our findings suggest that pre-K expansion policies may benefit the entire school community.
