† Not applicable; student school week variable is used as the denominator.
NOTE: Due to school-level nonresponse, estimates in the row reporting "Length of student school week" are not available for all teachers in the sample. The reported estimates are for those teachers from responding SASS schools. Estimates in the "Percentage of student school week" columns are similarly affected. Detail may not sum to totals because of rounding.
