NAEP Technical DocumentationIneligible Schools for the 2005 National Science Assessment

The Common Core of Data (CCD) public school file from which most of the sampled schools were drawn corresponds to the 2002-03 school year, some two years prior to the assessment school year. Some of the schools in the national science school samples were found to be ineligible (closed, not in scope, no longer offering grade, etc.).

The table below presents unweighted counts and percents of ineligible schools, by eligibility status, for the school samples.

Sampled schools in the beta sample, national science assessment, by grade and eligibility status: 2005
