However, if the scores are being used to select individuals above a certain score, different individuals would "pass" under the two methods of estimation. Furthermore, if individuals from different groups are being considered, then two individuals with the same observed score may not necessarily pass under the regressed-estimate approach.

In criterion-referenced measurement, the estimate of what the individual can do should depend only on his or her performance on the test and not on the performance of the population to which an individual belongs.
