NAEP Technical DocumentationSchool Nonresponse Weight Adjustments for the 2016 Assessment

			Development of Initial School Nonresponse Cells  Development of Final School Nonresponse Cells  School Nonresponse Adjustment Factor Calculation

The school nonresponse adjustment procedure inflates the weights of participating schools to account for eligible nonparticipating schools for which no substitute schools participated. The adjustments are computed within nonresponse cells and are based on the assumption that the participating and nonparticipating schools within the same cell are more similar to one another than to schools from different cells. Nonresponse cell definitions varied for public and private schools.
