The National Park Service Teacher-Ranger-Teacher (TRT) program is an extended professional development opportunity for educators from K-12 schools to learn about the resources and educational materials available through the National Park Service. The Teacher-Ranger-Teacher program at Independence National Historical Park helps teachers understand the importance of historical preservation, improves the park's education programs, and provides stronger links between the National Park Service and the School District of Philadelphia.
