PLUS is a two-year credentialing program designed to help novice school leaders manage teachers effectively, improve teaching through coaching and feedback, and create a supportive learning environment in schools. RAND Corporation researchers were asked to evaluate the implementation and outcomes of the PLUS program in one district from 2015 to 2018.
- Students of teachers coached by PLUS APs had somewhat larger English language arts (ELA) achievement gains than students of comparison teachers who received business-as-usual district supports.
- Teachers whose students had very low achievement gains departed the district at higher rates if they had received coaching and observation from PLUS APs.
- PLUS APs were not significantly different from other new APs in the rates at which they remained in the district or were promoted to principal roles.
