This report presents selected findings from the 2021-22 Principal Follow-up Survey (PFS). The PFS is a longitudinal component of the National Teacher and Principal Survey (NTPS), which is a nationally representative survey of public and private K-12 schools, principals, and teachers in the 50 states and the District of Columbia. The National Center for Education Statistics (NCES) conducted the 2021-22 PFS as a follow up to the 2020-21 NTPS to provide attrition and mobility information about principals in K-12 public and private schools. The purpose was to assess how many principals from the 2020-21 school year still worked as a principal in the same school during the 2021-22 school year ("stayer"), how many had moved to become a principal in another school ("mover"), and how many were no longer working as a principal ("leaver").
