Improving the Reliability and Interpretability of Value-Added Scores for Post-Secondary Institutional Assessment Programs
Steedle, Jeffrey T.
Online Submission, Paper presented at the Annual Meeting of the American Educational Research Association (Denver, CO, Apr 30-May 4, 2010)
Tests of college learning are often administered to obtain value-added scores indicating whether score gains are below, near, or above typical performance for students of given entering academic ability. This study compares the qualities of value-added scores generated by the original Collegiate Learning Assessment value-added approach and a new approach that employs hierarchical linear modeling (HLM). Results indicate that value-added scores produced by the two approaches are correlated and would be identical if larger student samples were available. The new approach produces value-added scores that are slightly more reliable and display substantially greater consistency across years. Furthermore, the HLM-based approach provides school-specific indicators of value-added score precision, which improve interpretability. For these reasons, the new approach is recommended for future institutional assessment programs. Detailed specification of HLM-based value-added approach is appended.
