Retaining college-level science, technology, engineering, and mathematics (STEM) students remains a priority in higher education. A variety of methods have been shown to increase retention, including mentorship, tutoring, course enhancements, community building, and engagement in high-impact practices such as undergraduate research. In 2011, an Office of Undergraduate Research at a large research university developed a program that incorporates multiple forms of student-centered programming with a focus on research. Learning Environment and Academic Research Network (LEARN) is a living-learning community wherein first-year students live in the same residence hall, take specific classes together, work with mentors, and engage in a 12-week mentored research apprenticeship. LEARN aims to recruit first-generation and underrepresented students. Such a program requires input and participation from numerous stakeholders. This article provides reviews of the development, implementation, and lessons learned from starting the program. To date the program has many early signs of success, including exceeding recruitment goals, higher GPA and retention rates, gains in student learning, and high levels of engagement in academic and leadership experiences.
