The following table presents unweighted counts and weighted response rates at grade 4 for sampled eligible and participating schools. States with Trial Urban District Assessment (TUDA) districts are shown in multiple rows: for the TUDA district(s) and for the state as a whole (the TUDA district[s] plus the rest of the state). The weighted response rates use the student enrollment from the sample frame divided by the school probability of selection. The weighted aggregation for the eligible schools for each jurisdiction is an estimate of the total population of students in the grade within each jurisdiction.
Participation is effectively mandatory for all states and districts, but not for Bureau of Indian Education (BIE) or Department of Defense Education Activity (DoDEA) schools.
Jurisdiction | Number of sample eligible schools | Number of participating schools | Weighted school response rates (percent) |
---|---|---|---|
NOTE: School counts are rounded to nearest ten. Detail may not sum to totals because of rounding. Percentages are based on unrounded counts.
