! 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).
1School 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.
2School 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.
3Schools that don’t participate in the free or reduced-price lunch program are included with the "0–34" percent category.
NOTE: A specialist works with students and a coach works with teachers. Academic coaching includes observing lessons, providing feedback, and demonstrating teaching strategies. Data are weighted estimates of the population. Detail may not sum to 100 because schools could report one than one type of specialist or academic coach.
