The 2017-18 National Teacher and Principal Survey (NTPS) is a state and nationally representative sample survey of public and private K-12 schools, principals, and teachers in the 50 states and the District of Columbia. NTPS collects data on core topics including teacher and principal preparation, classes taught, school characteristics, and demographics of the teacher and principal labor forces. This report presents selected findings from the Public and Private School Data Files of the 2017-18 NTPS, representing results of the second collection of NTPS. The 2017-18 NTPS uses a school-based sample of public and private schools. All principals associated with the sampled public and private schools were also included in the sample. Teachers associated with a selected school were sampled from a list of teachers that was provided by the school, collected from school websites, or purchased from a vendor. The purpose of this First Look report is to introduce new data through the presentation of tables containing descriptive information. Three appendices are included in the report.
