NAEP Technical DocumentationStudent Response and Exclusion Rates for Science Bridge

The table below presents the weighted student response and exclusion rates for the science bridge study, by private school type, for each grade for the private school samples. 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) students as a percentage of all absent, assessed, and excluded students.
