! 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).
¹ Interpret data on city teachers with caution. After nonresponse adjustments, the nonresponse bias for this category is greater than for other characteristics.
NOTE: This table only shows the first reported certificate that certifies teachers to teach in their state. Teachers include both full-time and part-time teachers. Detail may not sum to totals because of rounding and because some data are not shown.
