<p>Admissions rate and matriculation rate are not the same thing. Matriculation rate has little to do with the difficulty of being accepted in the first place. It is simply a measure of the percentage of students who enroll out of the percentage of students who are admitted. That does not measure the chance of acceptance and only has a marginal impact on the admissions rate.</p>
<p>Furthermore, a pure admissions rate is not the only measure of selectivity. One must consider other factors such as SAT scores and % of students in the top 10% 25% of class etc. Just because University of Chicago has a (relatively) high acceptance rate does not mean it is an “easy” school to get into.</p>
