The minimum chi(2) method for computing equating coefficients for tests with dichotomously scored items was extended to the case of Samejima's graded response items. The minimum chi(2) method was compared with the test response function method (also referred to as the test characteristic curve method) in which the equating coefficients were obtained by matching the test response functions of the two tests. The minimum chi(2) method was much less demanding computationally and yielded equating coefficients that differed little from those obtained using the test response function approach.
