The NTPS is the largest, most extensive survey of schools, principals, and teachers in the United States today. It includes data from public and private elementary and secondary schools. Public charter schools are also included in the study.
NTPS data have been collected in the 2015–16 and in the 2017–18 school year. However, the collected data resemble those collected in previous iterations of the SASS, which allow for the examination of trends over time. Relative to the 2011–12 SASS, the 2015–16 NTPS did not produce state-representative estimates. Rather, the 2015–16 NTPS produced nationally representative estimates for public schools, principals, and teachers. This will allow analysts to gain a holistic view of the principal and teacher labor market. In the 2017–18 cycle, both national and state-level estimates were supported for public schools, principals, and teachers. For public schools, the sample was designed to produce national estimates for a wide range of topics by charter status, community type, school level, school size, and free and reduced-price lunch enrollment, as well as estimates by state.
The NTPS collects extensive data on teachers, principals, and schools. Information on teachers includes their qualifications, career paths, professional development needs and activities, and support for these aspects of teachers' careers by the school and district. The NTPS school principal questionnaire collects information about principals’ or school heads' years of experiences and training, goals and decision making, professional development, and perceptions of school safety and work conditions. Information about schools includes enrollment, school year, staffing, school climate, and programs offered.
The NTPS data can be used by a wide variety of people interested in K-12 education, including teacher professional organizations, education advocacy groups, legislators, researchers, and journalists.
