			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. Exactly how nonresponse cells were defined varied for public and private schools.
