This article focuses on California's efforts to improve the alignment between K-12 and postsecondary schooling through the Early Assessment Program (EAP). Implemented in 2004, the EAP was designed to give high school students information about their academic preparedness for postsecondary education and to encourage teachers to teach for college readiness. I describe the EAP and its evolution and presence at California's community colleges. I then match EAP and other test score data for California high school juniors to administrative data from California community colleges to investigate the extent to which high school student participation in the EAP predicts their college course placement and influences their academic performance. I find that very few students enter the California community college system ready for college level work based on the EAP exam, but that the EAP can better serve community college campuses in their efforts to place students in developmental coursework.
