NAEP Technical DocumentationIneligible Public Schools for the 2012 Economics Assessment

The Common Core of Data (CCD) public school file from which most of the sampled schools were drawn corresponds to the 2008-2009 school year, 3 years prior to the assessment school year. During the intervening period, some of these schools either closed, no longer offered the grade of interest, or became ineligible for other reasons. In such cases, the sampled schools were considered to be ineligible.

The table below presents unweighted counts of sampled public schools for twelfth grade by eligibility status, including the reason for ineligibility.
