The Single Group with Nearly Equivalent Tests (SiGNET) Design for Equating Very Small Volume Multiple-Choice Tests. Research Report. ETS RR-11-31
Grant, Mary C.
Educational Testing Service
The "single group with nearly equivalent tests" (SiGNET) design proposed here was developed to address the problem of equating scores on multiple-choice test forms with very small single-administration samples. In this design, the majority of items in each new test form consist of items from the previous form, and the new items that were administered as unscored items in the previous form. Each form is equated using data from examinees who took the previous form. As the equating is a single-group design, with the 2 forms having a large number of overlapping items, the size of the equating sample can be much smaller than in other designs. (Contains 5 figures.)
