A confidence interval is a range of values that describes the uncertainty surrounding an estimate. Throughout the Condition of Education, confidence intervals are calculated as the estimate +/- the margin of error, based on a 95 percent level of confidence. This means that there is 95 percent certainty that the range includes the true or actual value of the statistic.

Users can select years at irregular intervals. However, as a result, the distance between the data points will not be proportional to the number of years between them.

# Rounds to zero.

! Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 and 50 percent.

‡ Reporting standards not met. Either there are too few cases for a reliable estimate or the coefficient of variation (CV) is 50 percent or greater.

NOTE: To estimate the margin of error, the standard error is scaled based on the desired level of confidence in the estimate. Throughout the Condition of Education, margins of error are produced based on a 95 percent level of confidence. Margin of error is calculated as 1.96*standard error. Excludes teachers who teach only prekindergarten. Data are based on a head count of full-time and part-time teachers rather than on the number of full-time-equivalent teachers. Detail may not sum to totals because of rounding. Race categories exclude persons of Hispanic ethnicity. Although rounded numbers are displayed, the figures are based on unrounded data.
