My info in terms of UVa is old and they seem to be doing more in terms of reaching out to kids these days-with admissions blogs, there is an admissions dean on the UVa forum here, etc. I think UVa came to our school once but it is a large diverse urban school. They may have some schools that they target more. Only about 10 or less kids a year end up at UVa from our high school. Not that many apply in comparison to some schools (like TJ in Northern Virginia). There was no personal outreach or phone calls, letters from anyone in admissions to my son but as I said that was a few years ago. Not sure they need to do that as much with instate kids (sounds like Michigan just sends a postcard or two). Sounds similar in terms of getting much more info, brochures, emails,etc. from other schools. My son applied ED (when they still had it) so I guess there really was no reason to contact him. They knew he was coming! Admissions even told ED kids not to come to accepted students day type events because they were already committed to coming . I’m glad they moved to EA. My son did get an invitation before application time to attend an event held in our city that UVa reps were at but it was part of a bunch of schools that were touring together-Harvard, Duke, Penn , Georgetown and UVa if I recall correctly.
Your son has some great options! Good luck with this tough decision.
