NAEP Technical DocumentationResponse, Exclusion, and Accommodation Rates for Grade 8 Mathematics Assessment in 2005

The following table displays the school- and student-level response and exclusion rates for the grade 8 mathematics assessment. Various weights were used in the calculation of the rates, as indicated in the column headings of the table.

Response, exclusion, and accommodation rates, grade 8 mathematics assessment, by school type and geographic region: 2005
School type and geographic region Number of schools in the original sample, rounded School participation rates (percent) before substitution (weighted by base weight and enrollment) School participation rates (percent) before substitution (weighted by base weight only) School participation rates (percent) after substitution (weighted by base weight and enrollment) School participation rates (percent) after substitution (weighted by base weight only) Number of students sampled, rounded Weighted percent of students excluded Weighted student participation rates (percent) after make-ups Weighted percent of assessed students accommodated
