In a compensatory criterion referenced test (CRT) it is common that the test developer maximizes the test information at or near the cut score location. This is believed to produce the highest classification accuracy. However, a recent study showed that the optimal location to maximize test information for highest classification accuracy (CA) and consistency (CC) also depends on factors such as test length, cut score location, the examinee ability distribution, and the test model applied for latent trait estimation (Wyse & Babcock, 2016). Moreover, when unintentional secondary dimensions are also measured (nuisance dimension caused by test construction, test standardization, or …
