Old school, prestigious, and that name goes a long way down the road. Darthmouth is a liberal arts school, so comparing it with, say, MIT or UCB, for research achievements in hard core science and engineering is meaningless. This is especially true since your child is making a decision on undergrad education. If you have never been to New England, it might be worthwhile for you to visit their campus and feel the difference. The down side is that, unlike UC Berkley or UCLA, Dartmouth is in the middle of no where.
And yes, Wall Street loves Dartmouth.
