# Round to zero.
! Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 percent and 50 percent (i.e., the standard error is at least 30 percent and less than 50 percent of the estimate).
‡ Reporting standards not met. The coefficient of variation (CV) for this estimate is 50 percent or greater (i.e., the standard error is 50 percent or more of the estimate) or the response rate is below 50 percent.
1 Elementary schools are those with any of grades K–6 and none of grades 9–12.
2 Operating hours were calculated by multiplying the reported length of school day (in hours and minutes) for each school by the number of days in the school year for students in each school.
NOTE: Detail may not sum to totals because of rounding and because some data are not shown.
