A Comparison of the Partial Credit and Graded Response Models in Computerized Adaptive Testing.

De Ayala, R. J.; And Others

Applied Measurement in Education, v5 n1 p17-34 1992

A study involving 1,000 simulated examinees compared the partial credit and graded response models in computerized adaptive testing (CAT). The graded response model fit the data well and provided slightly more accurate ability estimates than those of the partial credit model. Benefits of polytomous model-based CATs are discussed. (SLD)
