We examine the availability of physics in high schools in each U.S. state. We consider factors that affect availability, including the size of the high school and whether the school is public or private. This report includes maps that highlight states in which physics is more readily available and those in which it is less accessible. Future reports will examine the number of students taking physics in U.S. high schools, the types of physics being taught, and teacher and student demographics. The latest data in this report is from our 2008-09 Nationwide Survey of High School Physics Teachers.
