This report, the latest in a series of studies by the Center for an Urban Future examining opportunities to expand economic mobility in New York City, takes an in-depth look at college readiness and success among the city's public high school students. It explores opportunities to dramatically boost the rate at which New York City's students enter a best-fit college and graduate with a degree or other credential. Funded by The Clark Foundation, this report draws on data furnished by the New York City Department of Education (DOE) and City University of New York (CUNY), as well as data prepared by the New York State Education Department (NYSED), the Higher Education Services Corporation, Graduate NYC, and the Research Alliance for New York City Schools. In addition, this research included dozens of interviews and focus groups with officials at DOE, CUNY, high schools and colleges, affinity groups, and community-based organizations, as well as leading academic researchers, policy advocates, and high school and college students from across the five boroughs.
