I like to think about it this way: McIntire is a very prestigious program. They want a variety of students to apply so that they can get more people to choose from. If they post a profile then that would limit the diversity within the applicant pool. For instance, if they say that you need a really high GPA then most people would simply focus on their GPA and they would get a bunch of book worms. McIntire wants interesting people and posting a profile would certainly make it less interesting.
GPA is not all that matters. The statistics this year shows that they admitted a student with a 3.3 overall GPA. And my friend’s son last year was denied with a 3.8 (he had no extracurriculars).
