A private education is expensive, and seeing the value in that expense can make a big difference to you and your family. In many cases realizing value in the cost of a private education means securing an interest in the institution that amounts fairly to your out-of-pocket expense. This is valuing what you pay for; the flip-side of getting what you pay for!
Research the institution thoroughly. The internet makes this easier to do on some levels, but your best bet is to visit the campus and spend time with the students, the faculty, and the regional deans in the Office of Admission. Be assertive, and get your questions answered both by asking and by doing. Become familiar with the institution now, and when it really comes time to consider expense, you will have added much more value behind the dollar figures on the page.
