The Lollipop Test (La Prueba Lollipop) is a bilingual preschool readiness test (in both English and Spanish) that has been the subject of a number of studies to assess validity and detect cultural bias. Such studies have not dealt with item analysis as a way to measure cultural fairness. The Rasch model was used in a study of the Lollipop test which considered its cultural bias, the usefulness of the Rasch model, and the utility of the new software, IPARM. Subjects were 61 4- and 5-year-olds in Georgia and Florida (25 white, 24 black, and 12 Hispanic Americans). Results do not suggest gender or cultural bias for the test as a whole. The potentially biased items favor female or Hispanic students. The Rasch approach was useful, and the software was easy to use, presenting results on item functioning in easily understood format. Five tables present study data. (Contains 10 references.) (SLD)
