The Teaching Performance Record (TPR) is part of a complete professional development system for teachers. Created by researchers at the University of Virginia, the TPR offers a valid, reliable, proper, and useful method to collect information on teaching and student in-class behavior. Based on the latest educational research, the TPR describes the extent to which teachers behave in ways that influence students' academic learning and their intellectual involvement in classes. The system produces informative reports on classroom practices, which can serve as professional development targets for individual teachers and for whole faculties.
