Document Number: 3275Value-Added Assessment: An Accountability Revolution - Value-added assessment is a method of evaluating academic progress by comparing each studentís current scores on an assessment with their own previous scores. This report suggests that because value-added assessment does not depend on indiscriminate benchmarks, it objectively illustrates student progress and enables parents, taxpayers and policymakers to see how well schools are doing without penalizing disadvantaged schools. The method also evaluates teachers according to demonstrated results of student learning. The report asserts that the only disadvantage in using value-added assessment is that it must be supplemented with average levels of achievement and appropriate national norms against which these may be judged.
