Ineligible Public Schools for the 2006 Assessment

The Common Core of Data (CCD) public school file from which most of the sampled schools were drawn corresponds to the 2003-2004 school year, two 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 were 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 by grade and eligibility status.
