You don’t seem to understand that colleges don’t “recruit” students, they do outreach and information sessions. Athletic coaches “recruit”; admissions representatives provide information and may conduct interviews. The whole point of the school visits is to reach out to students who would not likely have an opportunity to visit the campus or attend an on campus information session. And visits are scheduled by high school staff, usually guidance counselors – it’s not like the admissions staff just randomly shows up. So if they has never been a person from Mt. Holyoke visiting your school, it’s probably because no one on your school’s staff has ever asked.
So simple question: have you tried figuring out who the regional rep at Mt. Holyoke is for your area, and contacting that person and asking if she can come to your school?
Because that is how these things are arranged.
