NAEP Technical DocumentationSchools and Enrollment in Public School Sampling Frame for the 2010 Public School Assessment

The following table presents the number of schools and estimated enrollment for the public school frame for grades 4, 8, and 12. The unweighted estimated enrollment is restricted to the selected primary sampling units (PSUs). The weighted estimated enrollment incorporates the PSU weight (inverse of the probability of selecting the PSU), and thus is a national estimate of the number of public school students in each grade.
