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

The student nonresponse adjustment procedure inflates the weights of assessed students to account for eligible sampled students who did not participate in the assessment. These inflation factors compensate the weights for the loss of data associated with absent students. Like its
counterpart at the school level, the student nonresponse adjustment is intended to reduce the mean square error and thus improve the accuracy of NAEP assessment estimates.
