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

The following table presents the weighted student response and exclusion rates for the science interactive computer tests (ICT) assessment. The exclusion rates give the percentage excluded, among all eligible students. Excluded students must be either students with disabilities (SD) or English language learners (ELL). The response rates indicate the percentage of students assessed among those who it was intended would take the assessment from within the participating schools. Thus, students who were excluded are not included in the denominators of the response rates.
