NAEP Technical DocumentationNew-School Sampling Frame for the 2012 Public School Economics Assessment

The most current Common Core of Data (CCD) file available was used to construct the public school frame for NAEP 2012. However, the information on that file was 3 years out of date by the time of the NAEP assessment. During that 3-year period, some schools closed, others changed grade span, and still others came into existence.

One can improve coverage by asking districts to provide information on currently open schools that were not listed on the 2008-2009 CCD file used to create the NAEP public school frame, and also to report grade span changes that may have caused a CCD-listed school to become newly eligible for twelfth grade. Asking all districts to do this would have imposed an undue burden, so instead, a random sample of districts was contacted to obtain lists of new and newly eligible schools. The goal was to allow every new or newly eligible school a chance of selection, thereby fully covering the target population of schools in operation during the 2011-2012 school year.

The development of a new-school frame for economics was conducted as part of the new-school procedure that was described for the long-term trend assessment. At the end of the process the new-school frame for economics was obtained by subsetting the overall new-school frame to eligible twelfth-grade schools in the certainty PSUs.
