​​​​NAEP Technical DocumentationEighth-Grade Schools and Enrollment in the 2022 Private School Civics and U.S. History Sampling Frame

The following table presents the numbers of eighth-grade private schools and estimated enrollments, as contained in the Private School Universe Survey (PSS)-based sampling frame, by private school affiliation, for the national assessments in civics and U.S. history.

The counts presented below are of schools with known affiliation. Schools with unknown affiliation do not appear in the table because their grade span, affiliation, and enrollment were unknown. Although PSS is a school universe survey, participation is voluntary and not all private schools respond. Since the NAEP sample must represent all private schools, not just PSS respondents, a small sample of PSS nonrespondents with unknown affiliation was selected to improve NAEP coverage.
