In this study, we compare SpringBoard® (SB) schools that had continuously used the SB English Language Arts (ELA) curriculum for at least three years with comparable non-SB schools. For high schools, the outcomes examined were school-level AP® participation and performance for a) all AP subjects, b) ELA and social science AP subjects, and c) ELA only subjects. AP performance was defined as the percentage of students among graduating seniors scoring 3 or higher in at least one AP Exam. We report comparison results for all students in schools, and for three subgroups--black, Hispanic, and first-generation college-going students. For middle schools, the outcome examined was school-level FCAT reading scores among eighth-graders.
