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

1 Teachers were classified as elementary or secondary on the basis of the grades they taught, rather than the level of the school in which they taught. In general, elementary teachers include those teaching prekindergarten through grade 6 and those teaching multiple grades, with a preponderance of the grades taught being kindergarten through grade 6. In general, secondary teachers include those teaching any of grades 7 through 12 and those teaching multiple grades, with a preponderance of the grades taught being grades 7 through 12 and usually with no grade taught being lower than grade 5.

2 Includes American Indian/Alaska Native, Asian, and Pacific Islander; for 2003-04 and later years, also includes Two or more races.

NOTE: Teachers who taught only prekindergarten students are excluded. Includes teachers in both traditional public schools and public charter schools. Instructional level divides teachers into elementary or secondary based on a combination of the grades taught, main teaching assignment, and the structure of the teachers' class(es). Race categories exclude persons of Hispanic ethnicity. Detail may not sum to totals because of rounding. Some data have been revised from previously published figures.
