NAEP Technical DocumentationDevelopment of Final Student Nonresponse Cells

Initial cells that did not satisfy the criteria defined below were combined with other clearly defined neighboring cells, resulting in the final student nonresponse cells.

The final student nonresponse cells had to meet the following criteria:

• at least 20 sampled students in the cell;

• at least 15 sampled schools in the cell with nonzero replicate weights for each replicate;

• maximum student nonresponse adjustments and replicate student nonresponse adjustments of 2.0; and

• replicate student nonresponse adjustments no larger than 1.5 times that of the corresponding student nonresponse adjustment.
