Colleges have long relied on their students to serve as campus tour guides -- not only showing people around, but recruiting the next cohort of students. A new program at the University of Virginia adopts the same model: New graduates are being sent into low-income high schools across the state to work for a year helping talented students apply for college. The recent graduates explain to students why they should consider college -- and show them how to apply to the best possible college and how to seek aid.
