Comparison of Three Different Item Banking Methods for Longitudinal Test Equating.
Rubin, Lois S.; Mott, David E. W.
Three different item-bank maintenance procedures were compared for the purpose of investigating their cumulative effects on a series of longitudinal equatings of tests measuring the same characteristic. Item data used resulted from Rasch one-parameter latent trait test calibrations. Comparison of the results in the various final banks were made. These included comparing mean item difficulty values, ability scores, and the number of correctly answered items necessary for passing the tests. These comparisons were made on the following data: a test comprised of the original 54 items and their difficulty values both in the initial bank and in the final banks, and, also, the difficulty values of items used as a test in the final administration of this study. No significant differences were found in the cumulative effects resulting from the various procedures. (Author)
