TVAAS

TVAAS, or Tennessee Value-Added Assessment System, is a tool used to measure a teacher’s impact on student learning over time. It analyzes students’ test scores to determine how much progress they make academically under a particular teacher’s instruction, accounting for factors like students' backgrounds. This helps evaluate teaching effectiveness more accurately than just test scores at a single point in time. By focusing on growth, TVAAS provides insights into how well teachers are supporting student learning year after year, aiding in professional development and ensuring educational quality.
