NAEP Technical DocumentationResponse, Exclusion, and Accommodation Rates for Grade 4 Science Assessment in 2005

The following table displays the school- and student-level response and exclusion rates for the grade 4 science 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 4 science 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
