I doubt that the acceptance rate for PA schools is published. That said, I’m sure that if the student has the stats and has a smart app list, s/he will get into PA school whether s/he goes to UAH or another fine school.
Getting into PA school is about GRE score, GPA, science GPA, 1000-3000 hours of hands-on clinical patient experience, etc.
Are you instate for UAH? Also look at UAB. My son’s GF went to UAB for undergrad and PA school.
