NAEP Technical DocumentationSchool and Student Participation Rates for the 2007 National Private School Assessment

The following is a link to tables that present response rates for the NAEP 2007 private school samples for fourth, eighth, and twelfth grades in the mathematics, reading, and writing operational assessment. The table shows response rates before and after substitutes were included for originally sampled nonrespondents. The tables present a breakdown by private school type, as response rates varied considerably across Catholic and non-Catholic school types.

School response rates, before and after substitution, mathematics, reading, and writing operational study

The following are links to tables that present the overall weighted student response rates and exclusion rates for the mathematics, reading, and writing operational study separately, by private school type, for the private school samples in fourth, eighth, and twelfth grades. In every NAEP survey, some of the sampled students are not assessed for the following reasons:

withdrawn students,
excluded students with disabilities (SD),
excluded English language learner (ELL) students, or
students who are absent from both the original session and the makeup session (not excluded but not assessed).

Withdrawn students are those who have left the school before the original assessment. Excluded students are those who cannot be assessed, even with an accommodation, because they are classified as SD and/or ELL and the school has determined that the students cannot meaningfully participate in the NAEP assessment in the assigned subject. Other students who are absent for the initial session are assessed in the makeup session. The last category includes students who were not excluded (i.e., "were to be assessed") but were not assessed due either to absence from both sessions or because of a refusal to participate.

Assessed students are also classified as assessed without an accommodation or assessed with an accommodation. The latter group can be divided into SD students assessed with an accommodation, ELL students assessed with an accommodation, or students who are both SD and ELL and accommodated. Note that some SD and ELL students are assessed without accommodation, and students who are neither SD nor ELL can only be assessed without an accommodation.
