NAEP Technical DocumentationWeighted Student Response Rates and Exclusion Rates, Science Assessment

The following table presents the overall weighted student response rates and exclusion rates for the science assessment. 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 are English language learners (ELL) as a percentage of all absent, assessed, and excluded students. Note that the table only includes those jurisdictions participating for science.
