Tennessee Value-Added Assessment System (TVAAS)

The Tennessee Value-Added Assessment System (TVAAS) is a way to measure how much a teacher's students improve academically over time. It analyzes student test scores to determine the contribution of each teacher to student progress, adjusting for factors like students' initial skills and backgrounds. This helps evaluate teaching effectiveness objectively, focusing on student growth rather than just test performance at a single point. TVAAS provides insights into how well teachers support student learning, informing decisions about instruction and professional development, with the goal of improving educational outcomes across the state.
