NAEP Technical DocumentationParticipation, Exclusion, and Accommodation Rates for Grade 4 Geography for the 2010 Assessment

The following table displays the school- and student-level participation, exclusion, and accommodation rates for the grade 4 geography 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 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 4 geography assessment, by school type and geographic region: 2010
