NAEP Technical DocumentationParticipation, Exclusion, and Accommodation Rates for Grade 8 Mathematics

The following table displays the school- and student-level response, exclusion, and accommodation 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.

The participation rates reflect the participation of the original sample schools only and do not reflect any effect of substitution. The rates weighted by the base weight and enrollment show the approximate proportion of the student population in the jurisdiction that is represented by the responding schools in the sample. The rates weighted by just the base weight show the proportion of the school population that is represented by the responding schools in the sample. These rates differ because schools differ in size.

Participation, exclusion, and accommodation rates, grade 8 mathematics assessment, by school type and geographic region: 2009

School type and geographic region	Number of schools in original sample	School participation rates (percent) before substitution (weighted by base weight and enrollment)	School participation rates (percent) before substitution (weighted by base weight only)	Number of students sampled	Weighted percentage of students excluded	Weighted student participation rates (percent) after makeups	Weighted percentage of students accommodated
