Linked Learning is an educational approach that combines college-focused academics, rigorous technical education, work-based learning, and personalized student supports in small, career-themed high school academies contained in multiple schools (i.e., small schools within larger comprehensive schools) in the same district. A leading architect of the Linked Learning approach to education, ConnectEd: The California Center for College and Career Readiness (ConnectEd) forms partnerships with districts in which they collaborate with educators and administrators to help build high-quality Linked Learning academies. In 2013, ConnectEd received an Investing in Innovation (i3) Development grant to support the development of Linked Learning career-themed academies in four high schools in San Bernardino City Unified School District (SBCUSD). The Linked Learning San Bernardino (LLSB): Accelerating College and Career Readiness in Low-Performing Schools development grant supported both the development of new academies, as well as the further development of four existing California Partnership Academies (CPAs). This technical report begins with a discussion of the Linked Learning San Bernardino (LLSB) logic model in which key program components and intended outcomes are specified. Next is a description of the intervention followed by a description of the research design, including implementation fidelity and the two quasi-experimental designs; student samples; and data collection and analysis methods. The authors then present the findings on program implementation and student outcomes. This technical report does not include interpretation of these findings.
