Y’know, you probably have the data to do a quick-and-dirty check here. Take a look at the GRE/SAT scores on the applications (both for applicant pool and for accepted scholars). If most scholars have much-less-than-perfect scores, then you’re probably not hiring the top tier (standardized tests have a notoriously low ceiling). And assuming most scholars aren’t hitting the test ceiling, you can also test the hypothesis about different domains by looking at the test score distributions for scholars in the different areas.
