The
Common Core of Data (CCD)-based sampling frames, from which most of the sampled schools were drawn, correspond to the 2021–2022 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 school was coded as ineligible.
