NAEP Technical DocumentationReplicate Student Base Weights for Noncertainty Schools in the 2002 State Assessment

For sampled students k in noncertainty schools s, the replicate r base weights are defined as follows:

STUWGT_sk(r) = w_s(r) * SNRADJ_c(r) * SUBADJ_s * TRIM_s * WINSCHL_s * YRRND_s

where

• w_s(r) is the replicate school base weight (see Replicate School Base Weights);

• SNRADJ_c(r) is the replicate school nonresponse adjustment (see Replicate School Nonresponse Adjustment for the 2002 State Assessment);

• SUBADJ_s is a special factor for substitute schools (See School Base Weights for Substitute Schools);

• TRIM_s is the school trimming factor (See School Base Weights for New Schools);

• WINSHCL_s is the within-school student sampling probability; and

• YRRND_s is a special factor for year-round schools (see Student Base Weights for the 2002 State Assessment).
