Teachers in the SLC usually have common planning time to foster collaboration, development of interdisciplinary projects, and to track progress of individual students across subjects. These include several types, including: Theme-Based SLCs or Focus Schools, usually formed around a specific curricular theme, such as "Success Academy" or "Humanities"; grade-based SLCs or Houses, such as Freshman Academies which are structured to support students transitioning into higher-level schools; Career Academies, developed around a career theme or Career Clusters; Magnet Schools, career-themed SLCs that include accelerated course-work for Gifted & Talented students. This is reflected in the design of educational facilities with SLCs designed into separate clusters or groupings, often with a central common or flexible learning area at its heart of the cluster, with a variety of learning and group meeting rooms opening onto it, including several classrooms or learning studios, a science lab, and potentially a makerspace or vocational shop.
