Nationwide, close to 40 million adults lack a high school diploma or a General Educational Development (GED) credential. About a quarter of high school freshmen do not graduate in four years, and while many high school dropouts eventually do attend GED preparation classes, too few ever pass the GED exam or go on to college. Students with only a high school diploma already face long odds of success in a labor market that increasingly prizes specialized training and college education; for GED holders, the chances are even worse. MDRC partnered with LaGuardia Community College of the City University of New York (CUNY) to launch a small but rigorous study of its GED Bridge to Health and Business program, which aims to prepare students not only to pass the GED exam, but also to continue on to college and training programs. The results are highly encouraging: Bridge students were far more likely to complete the class, pass the GED exam, and enroll in college than students in a more traditional GED preparation class.
