IRT Observed-Score Equating with the Nonequivalent Groups with ...

You can equate forms with classical test theory (CTT) or item response theory (IRT). However, one of the reasons that IRT was invented was that equating with CTT was very weak. CTT methods include Tucker, Levine, and equipercentile. Right now, though, let’s focus on IRT. See more The need is obvious: to adjust for differences in difficulty to ensure that all examinees receive a fair score on a stable scale. Suppose you take Form A and get s score of 72/100 while … See more There are three general approaches to IRT equating. All of them can be accomplished with our industry-leading software Xcalibre, though conversion equating requires an additional software called IRTEQ. 1. … See more If you want to do IRT equating, you need IRT calibration software. All three approaches use it. I highly recommend Xcalibre since it is easy to use and automatically creates … See more Concurrent calibration is arguably the easiest but has the drawback that it merges the scales of each form into a new scale somewhere in the middle. If you need to report the scores on either form on the original scale, … See more WebDescriptors: Equated Scores, Scoring, Self Evaluation (Individuals), Scores, Test Items, Statistical Analysis, Data Collection, Item Response Theory, Scaling, Raw Scores, Tests, Vocabulary, Testing Educational Testing Service.
