NAEP Technical DocumentationWeighted Student Response and Exclusion Rates for the 2015 Twelfth-Grade Public School National Mathematics Assessment
The following table presents the weighted student response and exclusion rates for the 2015 mathematics assessment for twelfth-grade public schools. The exclusion rates give the percentage excluded, among all sampled students. Excluded students must necessarily be either students with disabilities (SD) or English learners (EL). The response rates indicate the percentage of students assessed among those who were intended to take the assessment within the participating schools. Thus, students who were excluded are not included in the denominators of the response rates.
| Region | Weighted student response rates (percent) | Weighted percentage of all students who were SD and excluded | Weighted percentage of all students who were EL and excluded |
