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. Certification type 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. Data on certification type are not available for private school teachers. Detail may not sum to totals because of rounding. Although rounded numbers are displayed, the figures are based on unrounded data.
