Welcome to the Guidance Office, a forum for readers of The Choice to seek expert advice about college admissions. The Choice has invited Janet Rapelye, the dean of admission at Princeton University, to answer select reader questions about applying to college. She is looking forward to fielding questions about finding the right college match and detailing what admissions officers look for in college applications. Ms. Rapelye is a graduate of Williams College who later became the dean of admissions at Wellesley College, where she served for 12 years. In 2003, Ms. Rapelye succeeded Fred Hargadon as Princeton's dean of admission. Mr. Hargadon, who retired after 15 years at the Ivy League institution, called Ms. Rapelye "one of the country's most respected admission deans" who "has a well-deserved reputation for her thoughtfulness, perceptiveness and good judgment." To pose a question to Ms. Rapelye, please use the comment box below. She has agreed to accept questions through Sept. Her first answers are scheduled to appear on Monday. Our Q. and A. with Ms. Rapelye is only the most recent of our Guidance Office sessions, which have drawn representatives from a broad range of colleges and universities, including Michael Barron of the University of Iowa; Dr. Marybeth Gasman and Dr. Walter Kimbrough, who answered questions about the nation's historically black colleges and universities; and Kay McClenney, an expert on community colleges. We encourage you to explore these archived posts and participate in future Guidance Office sessions.
