1 Education specialist degrees or certificates are generally awarded for 1 year's work beyond the master's level. Includes certificate of advanced graduate studies.
2 Refers to certification of teachers to teach in the state where they are currently teaching. A teaching certificate is probationary if all requirements have been satisfied except completion of a probationary period. It is provisional or temporary if additional coursework, student teaching, or passage of a test is required to obtain regular certification. It is a waiver or emergency certificate if a certification program must be completed to continue teaching.
NOTE: 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 reported in other tables. Teachers were classified as elementary or secondary on the basis of the grades they taught, rather than on 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 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 grades taught being grades 7 through 12 and usually with no grade taught being lower than grade 5. Detail may not sum to totals because of rounding and cell suppression. Race categories exclude persons of Hispanic ethnicity.
