! 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. Either there are too few cases for a reliable estimate, or 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: Data are weighted estimates of the population. “Stayers” are principals who were principals in the same school in the 2021–22 PFS school year as in the 2020–21 NTPS school year. “Movers” are principals who were still principals in the 2021–22 PFS school year but had moved to a different school from their 2020–21 NTPS school. “Leavers” are 2020–21 principals who were no longer principals in the 2021–22 PFS school year. Detail may not sum to totals because of rounding and because data for PFS principals with "other" status in the 2021–22 PFS school year are not shown. "Other" includes principals who had left their 2020–21 NTPS school, but for whom it was not possible to determine a mover or leaver status in the 2021–22 PFS school year.
