Career academies promote smaller learning communities within high schools, creating personalized learning environments while promoting students' readiness for college and careers. After describing the career academy structure, we present four research-based aspects that can assist school leaders and teachers in developing and implementing academies. We include practical examples from the Metro Nashville Public Schools, noting how educators have collaborated with civic agencies, businesses, and postsecondary partners to increase the graduation rate and improve student learning outcomes. Career academies can be effective in preparing students for college and careers, while also providing economic benefits to the community.
