Sampling Frame for the 2005 State Assessment


Fourth- and Eighth-Grade Schools and Enrollment in Public School Sampling Frame

New-School Sampling Frame

Drawing the school samples for the 2005 assessment required a comprehensive list of public schools in each jurisdiction containing information for stratification purposes. As in previous NAEP assessments, the Common Core of Data (CCD) file developed by NCES was used to construct the sampling frame. The CCD file corresponding to the 2002-03 school year provided the frame for all regular and state-operated public, BIA, and DoD domestic schools in the United States and its territories; DoD international schools; and schools in Puerto Rico.

The sampling frame excluded ungraded schools, vocational schools with no enrollment, special-education-only schools, prison and hospital schools, virtual or online schools, home-school entities, and juvenile correctional institutions. 

For quality control purposes, school and student counts from the sampling frame were compared to school and student counts from previous frames (2002 and 2003). No major issues were found.
