In 2017–18, the percentage of teachers who had completed a postbaccalaureate degree was higher for traditional public school teachers (59 percent) than for private and public charter school teachers (48 and 46 percent, respectively). The percentage of teachers who had less than a bachelor’s degree as their highest degree was lower for traditional public and public charter school teachers (3 percent each) than for private school teachers (10 percent).

In the 2017–18 school year, there were 3.3 million full-time and part-time traditional public school teachers, 205,600 public charter school teachers, and 509,200 private school teachers.1 The number of traditional public school teachers in 2017–18 was 12 percent higher than in 1999–2000 (3.0 million), the number of public charter school teachers in 2017–18 was 1,076 percent higher than in 1999–2000 (17,500), and the number of private school teachers in 2017–18 was 13 percent higher than in 1999–2000 (449,100).

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.
