For our Season 5 premiere, Admissions Beat turns its attention to high school juniors. Host Lee Coffin, dean of admissions at Dartmouth, previews what prospective applicants can expect in the months ahead. He encourages them to start with an “existential selfie” to understand what they’re seeking in a college experience. He and his guests also provide tips on building a college list and assessing a campus’s community and culture. Joining Dean Coffin are Thyra Briggs, vice president for admissions and financial aid at Harvey Mudd College, and Jacques Steinberg, co-author of “The College Conversation: A Practical Companion for Parents to Guide Their Children Along the Path to Higher Education.”
