# Rounds 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).
NOTE: BIE school refers to schools funded by the Bureau of Indian Education (BIE) that are operated by the BIE, a tribe, or a private contractor and not by a regular school district. Detail may not sum to totals because of rounding and because some data are not shown.
