NAEP Technical DocumentationParticipation, Exclusion, and Accommodation Rates for Age 13 Reading
The following table displays the school-level participation rates and student-level participation, exclusion, and accommodation rates for the age 13
long-term trend reading assessment. Various weights were used in the calculation of the school rates, as indicated in the column headings of the table. For the student participation rates, student base weights were used. For the student exclusion rates and accommodation rates, student base weights with adjustment for school nonresponse were used. Different weights were used at the student level because the student participation rates are conditional on (i.e., computed within) the participating schools, whereas the exclusion and accommodation rates are population estimates.
The school participation rates reflect the participation of the original sampled schools only and do not reflect any effect of substitution. The rates weighted by the school base weight and enrollment show the approximate proportion of the student population in the domain 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.
| Geographic region and school type | Number of schools in original sample | School participation rates (percent) before substitution (weighted by school base weight and enrollment) | School participation rates (percent) before substitution (weighted by school base weight only) | Number of students sampled | Weighted percent of students excluded | Weighted student participation rates (percent) after makeups | Weighted percent of students accommodated |
