! 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).
1Early career teachers are defined as those starting teaching no earlier than the 2016–17 school year.
2“Leavers” are 2020–21 teachers who were no longer teachers in the 2021–22 TFS school year.
3School level based on the definitions set by Common Core of Data (CCD). Elementary schools offer at least one grade of K through 4, and the number of elementary grades is at least as high as the number of middle grades. Middle schools offer at least one of grades 5 through 8, and the number of middle grades is greater than the number of elementary or secondary grades. Secondary/high schools are defined as schools that offer at least as many of grades 9 through 12 as in lower grades. Combined/other schools include all other combinations of grades, including K–12 schools. School level categories in the 2020–21 NTPS differ from those in previous survey administrations; caution should be exercised when comparing estimates by level over time.
4School level based on low and high grades offered by the school. Primary schools offer at least one grade lower than 5 and no grade higher than 8. Middle schools offer no grade lower than 5 and no grade higher than 8. High schools offer no grade lower than 7 and at least one grade higher than 8. Combined schools offer at least one grade lower than 7 and at least one grade higher than 8. Schools with only ungraded classes were included with combined schools. These categories are provided because they are comparable to those used in previous NTPS publications.
5Schools that don’t participate in the free or reduced-price lunch program are included with the "0–34" percent category.
6Teachers were asked whether they were male or female. Although this variable is labeled “sex,” the questionnaire did not use the terms either “gender” or “sex.”
7Higher than a master’s degree is defined as a teacher who completed any of the following: an educational specialist or professional diploma, a certificate of advanced graduate studies, or a doctorate or first professional degree.
8“Movers” are teachers who were still teachers in the 2021–22 TFS school year but had moved to a different school from their 2020–21 NTPS school.
9“Stayers” are teachers who were teachers in the same school in the 2021–22 TFS school year as in the 2020–21 NTPS school year.
NOTE: Data are weighted estimates of the population. Hispanic includes Latino.
