A method is proposed for the detection of item bias with respect to observed or unobserved subgroups. The method uses quasi-loglinear models for the incomplete subgroup x test score x item 1 x ... x item k contingency table. If the subgroup membership is unknown, the models are the incomplete-latent-class models of S. J. Haberman (1979). The…

Kelderman, Henk; Macready, George B. – 1988
The use of loglinear latent class models to detect item bias was studied. Purposes of the study were to: (1) develop procedures for use in assessing item bias when the grouping variable with respect to which bias occurs is not observed; (2) develop bias detection procedures that relate to a conceptually different assessed trait--a categorical…

A method is proposed to equate different sets of items administered to different groups of individuals using the Rasch model. A Rasch equating model was formulated to describe one common Rasch scale in different groups with different but overlapping sets of items. The item parameters can then be estimated simultaneously, avoiding different…

Samson, Digna M. M. – 1983
The traditional multiple-choice reading comprehension test of English as a second language, used in the Dutch school-leaving examinations, has been criticized for its apparent lack of construct validity. The Dutch National Institute for Educational Measurement has conducted a number of studies to determine whether there is a different skill…

Kreeft, Henk; Sanders, Piet – 1983
In the Dutch national examinations, reading comprehension tests are used for all languages. For the native language, reading comprehension is tested with reading passages and related questions to which the test-taker provides his own response, not choosing from a group of alternatives. One problem encountered in testing with these items is…

de Jong, John H. A. L. – 1983
The Rasch model for test analysis is a latent-trait model, which specifies the relationship between observable test performance and the unobservable traits or abilities assumed under test performance. In most cases, the test constructor has no clue as to whether the latent traits postulated by the model are indeed the abilities he wants to…
