PTRA began in 1985 with the mission of improving the teaching and learning of physics and physical science for all teachers and students in the United States. AAPT/PTRA is the leading in-service physics professional development program and has touched the lives of thousands of teachers and countless students. PTRA owes its success to many people and partners including PASCO and Vernier. THANK YOU for your continued support of PTRA and all you have done to support physics teachers.
