Equating Tests under the Graded Response Model.

Baker, Frank B.

Applied Psychological Measurement, v16 n1 p87-96 Mar 1992

The procedure of M.L. Stocking and F.M. Lord (1983) for computing equating coefficients for tests having dichotomously scored items is extended to the case of graded response items. A system of equations for obtaining the equating coefficients under the graded response model is derived. (SLD)
