For millions of American teenagers and their parents, adolescence is increasingly defined by one all-consuming goal: Getting into the right college. “Getting In” is a real-time podcast following a diverse group of New York-area high school seniors through the exhilarating and harrowing process of applying to college. The series is hosted by Julie Lythcott-Haims, the former Dean of Freshmen at Stanford University and author of “How to Raise an Adult.” The season will chronicle all the important steps along the way, from applications to (we hope) acceptances. The students will get advice from a stellar panel of experts, including former admissions officials from schools such as Princeton and UVA, and from experienced high school guidance counselors. The experts will also answer listeners’ questions. Nothing can remove the stress and uncertainty of the modern college application process, but “Getting In” aims to provide both teens and their parents with the kind of knowledgeable companionship that will at least make them feel they’re not alone.
