How can states ensure that students who are overage or under-credit (OA/UC) not only graduate high school but are prepared for college or the workforce? Competency-based education (CBE) is one emerging strategy for addressing the needs of at-risk youth. CBE can address the needs of at-risk students because it is personalized to individual students, offers self-paced instruction, and ensures mastery of specific content and skills. In this Ask the CCRS Center brief, we discuss how CBE can support OA/UC students and provide recommendations for how other states can develop and implement CBE policies. We highlight state policy examples utilizing CBE elements to improve high school graduation outcomes of OA/UC students from: Georgia; Illinois; Nevada; and Ohio.
