NAEP Technical DocumentationWeighted Student Response and Exclusion Rates for the 2009 State Science Assessment

The following table presents the overall weighted student response and exclusion rates for the science assessment. States with Trial Urban District Assessment (TUDA) districts are shown in multiple rows: for the TUDA district(s) and for the state as a whole (the TUDA district[s] plus the rest of the state). The weighted response rates utilize the student base weights and indicate the weighted percentage of assessed students as a percentage of all students to be assessed.The exclusion rates give the weighted percentage of excluded students with disabilities (SD) or English language learners (ELL) among all absent, assessed, and excluded students. Note that the table only includes those jurisdictions participating in the science assessment.
