Document Number: 3277 Teacher Effects as a Measure of Teacher Effectiveness: Construct Validity Considerations in TVAAS (Tennessee Value-Added Assessment System) PDF - Measurement experts at the University of Colorado provide a technical critique of the TVAAS as a valid measure of teacher effectiveness. The authors raise several questions about the methods used and how well they identify teacher effectiveness. A particular concern with TVAAS is that it doesn’t consider that high-achieving students are often assigned to highly effective teachers, so that the assessment of teacher effectiveness is magnified. The researchers argue that, since teaching quality in this model is defined solely in terms of raising student achievement, the model does not distinguish between good teachers and teachers who are teaching to the test.
