Unidimensional IRT Item Parameter Estimates Across Equivalent Test Forms With Confounding Specifications Within Dimensions
When constructing multiple test forms, the number of items and the total test difficulty are often equivalent. Not all test developers match the number of items and/or average item difficulty within subcontent areas. In this simulation study, six test forms were constructed having an equal number of...
