NAEP Technical DocumentationWeighted Student Response and Exclusion Rates for the 2007 National Private School Writing Assessment

The table below presents the weighted student response and exclusion rates for the writing operational 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 among all students to be assessed. The exclusion rates give the weighted percentage of excluded students with disabilities (SD) or English language learners (ELL) students among all absent, assessed, and excluded students.  The response rates indicate the percentage of students assessed among those who it was intended would take the assessment from within the participating schools.
