The Full Form of NTPS is‍ National Teacher and Principal Survey.

The National Teacher and Principal Survey (NTPS) is a system of related questionnaires that provide descriptive data on the context of public and private elementary and secondary education in addition to giving local, state, and national policymakers a variety of statistics on the condition of education in the United States. As a nationwide sample survey collecting information directly from teachers and principals, the NTPS provides an opportunity for the characteristics and experiences of school staff to inform analyses about the education sector. Redesigned from the Schools and Staffing Survey (SASS) with a focus on flexibility, timeliness, and integration with other ED data, the NTPS system allows for principal, teacher, and student characteristics to be analyzed in detail and supports the analysis of a variety of subgroups (e.g., female principals, Black or African-American teachers, rural schools)
