NAEP Technical Documentation Ineligible Private Schools for the 2022 Long-Term Trend Assessment
The Private School Universe Survey (PSS) school file from which most of the sampled schools were drawn corresponds to the 2019–2020 school year, two years prior to the assessment school year. During the intervening period, some of these schools either closed, no longer offered grades for the age group of interest, or were ineligible for other reasons. In such cases, the sampled schools were coded as ineligible.
The table below presents unweighted counts of sampled private schools by eligibility status, including the reason for ineligibility.
