NAEP Technical DocumentationTrimming Student Replicate Weights

The replicate weights adjusted for student nonresponse were trimmed using the trimming factor that was computed for the final student weight. Given STU_TRIM_jk as the final student trimming factor for student k in jurisdiction j, the replicate r weights adjusted for student nonresponse were trimmed as

FSTUWGT_jsk(r) = STUAWGT_jsk(r) × STU_TRIM_jk

where STUAWGT_jsk (r) represents the r^th replicate nonresponse-adjusted student base weight and FSTUWGT_jsk (r) represents the r^th replicate final weight for student k in school s in jurisdiction j.
