NAEP Technical DocumentationWeighted Counts of NAEP 2002 Eligible Sample Private Schools by Response Status, Eighth Grade

The following table presents student-weighted aggregations and response rates for eligible eighth-grade private schools, for nonresponding and responding originally sampled schools. These weighted aggregations for each set of schools were calculated by dividing the frame enrollment by the school probability of selection. The student-weighted aggregations for the eligible schools for each jurisdiction offer an estimate of the total population of students in the grade within each jurisdiction.
