| Abstract | The purpose of this paper is to report results on the development of a new computer-assisted methodology for creating parallel test forms using the item response theory (IRT) information function. Recently, several researchers have approached test construction from a mathematical programming perspective. However, these procedures require formidable computations, particularly as more constraints (i.e., the number of forms and the number of content areas) are added. In the test construction methodology proposed in this study, items are sampled from an ordered domain of item information values according to differences between test information curves of forms that are in the process of being created and a target test information curve. This new heuristic procedure, which uses a program known as TESTGEN, is being examined by the American College Testing (ACT) Program, which develops six parallel forms for the ACT Assessment Program each year. Research has concentrated on the Mathematics Usage Test. Results appear to be quite promising. Two data tables, one flowchart, and six graphs are presented. (Author/TJH) |
