During the 2008-09 school year, approximately 27,000 teachers in U.S. high schools taught at least one physics class. In this report, we detail these teachers' academic backgrounds and demographics. We also examine where physics fits in their teaching assignments. About one-third of the teachers teaching at least one high school physics course are women. The latest data in this report is from our 2008-09 Nationwide Survey of High School Physics Teachers.
