NAEP Technical DocumentationComputing Replicate School Nonresponse Adjustments

The replicate school nonresponse adjustments were computed as follows for each nonresponse weighting cell c. (The corresponding calculation of school nonresponse adjustments is given in Calculation of School Nonresponse Adjustments.)

where

• S_c^(A)  is the set of eligible sampled schools in cell c;

•  R_c^(A)  is the set of responding schools in cell c;

• w_s(r) is the replicate school base weight (see Computing School-Level Replicate Base Weights for details);

• SCHSES_s^(A) is the Session A school weighting adjustment (see School Base Weights for Originally Sampled Schools);

• TRIM_s is the trimming factor for school s (see Calculating Trimming Factors for New and Private Schools);

• x_s is the enrollment for school s; and

•  SUBADJ_s is the substitute-school adjustment for school s (see School Base Weights for Substitute Schools for details).
