An empirical comparison of the relative efficiency of verbal aptitude tests developed using two latent trait methods, the one- and three-parameter logistic models, is presented. When a well-defined item pool was used, the simple one-parameter logistic model was as efficient as the more complex model. (Author/PN)

Two methods of item selection were used to select sets of 40 items from a 50-item verbal analogies test, and the resulting item sets were compared for relative efficiency. The BICAL program was used to select the 40 items having the best mean square fit to the one parameter logistic (Rasch) model. The LOGIST program was used to select the 40 items…

The precision and efficiency of a cognitive test constructed by three different methods of item analysis was compared, using the verbal aptitude subtest of the Florida Twelfth Grade Test. Classical item analysis, factor analysis and the Rasch logistic model were used in the construction of 15 and 30 item subtests and replicated for samples of 250,…

Three methods of item selection were used to select sets of 38 items from a 50-item verbal analogies test and the resulting item sets were compared for internal consistency, standard errors of measurement, item difficulty, biserial item-test correlations, and relative efficiency. Three groups of 1,500 cases each were used for item selection. First…
