Equating Multiple Forms of a Competency Test: An Item Response Theory Approach.
A competency test was developed to assess students skills in using electronic library resources. Because all students were required to pass the test, and had multiple opportunities to do so, multiple test forms were desired. Standards had been set on the original form, and minor differences in form difficulty needed to be taken into account. Students were randomly administered one of six test forms; each form contained the original items and 12 pilot items that were different on each form. The pilot items were then calibrated to the metric of the original items and incorporated in two additional operational forms. Data were available for about 500 first-time examinees (college students) for each form. (Author/SLD)
