Types of Schools in NTPS:

The NTPS is a large sample survey of America's public and private elementary and secondary schools. Charter schools are included in the study.

The NTPS consists of four questionnaires:

• A Teacher Listing Form to obtain a list of teachers from each school. To reduce burden, a sample of teachers is selected from this list of all teachers at the school
• A School Questionnaire that obtains information on the characteristics of the school
• A Principal Questionnaire that collects information on the principal
• A Teacher Questionnaire that collects information on the sampled teacher.

The NTPS design produces estimates at the national level and is designed to support analysis of a variety of subgroups including: elementary, middle, high, and combined; federal free or reduced-price lunch program; urban, suburban, rural, and town; and traditional public and public charter school types.
