NAEP Technical DocumentationResponse, Exclusion, and Accommodation Rates for Age 17 Mathematics Assessment in 2004

The following table displays the school- and student-level response and exclusion rates for age 17 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, age 17 mathematics assessment, by school type and geographic region: 2004

School type and geographic region	Number of schools in the 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)	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
