How important is selectivity in evaluating colleges?
Many colleges rely on Resident Advisors to live in student dorms and serve as links between the college/university and its students, especially around residential life. The official duties of the "RA" often include: helping roommates work through conflicts, organizing and executing relationship-building events, maintaining student safety and well-being, passing along school-specific information, and serving as a general resource for helping students find what they need on campus, usually during the first year of college. The extent of an RA's role often very much depends on the school itself....some have a much more involved and structured RA system then others.
Because beginning college and thriving as a student often involves a large amount of change, your RA can be a great resource for helping your successfully navigate all of this change. You might even consider serving in the RA role yourself after your first year of college, especially if you find yourself taking advantage of your RA's support as a new student.
