UVA got 21,706 completed OOS applications this year for a target of 1,225 OOS seats. They had to make several offers per seat because the OOS yield is relatively low, but they still only made 4,986 OOS offers for a 22.97% OOS acceptance rate.

EA applications aren’t much better off, either. (Note that these numbers are part of the overall statistics above.)

And yes, the OOS applications (or at the least, those offered admission) tend to have better grades and test scores than the average Virginia resident application.
What this means to you: OOS admissions at UVA are really, Really competitive. Your class ranking is promising; your ACT score and weighted GPA don’t distinguish you among these applicants. Excepting maybe recruited athletes, you can consider UVA a reach for OOS applicants across the board. You can presume that most of them have good solid applications and good reason to believe that they have a reasonable shot at admission, and most of them are in fact denied admission.
This doesn’t mean you shouldn’t apply. It just means that anyone trying to predict your chances as an OOS applicant is purely guessing.
