This report examines enrollments in high school physics during the 2012-13 school year. We estimate that the physics-taking rate reached 39% for the year; that means that 39% of the graduates in the class of 2013 were enrolled in at least one physics course prior to graduation. Enrollments in physics courses reached an estimated 1.38 million students. AP physics and second-year physics courses were the fastest growing courses. We also find that students in private schools are more likely to take physics than those in public schools. These are the latest data from our 2012-13 Nationwide Survey of High School Physics Teachers.
