"Success Boston Coaching" is a coaching intervention for students who are traditionally underrepresented in college to help them transition from high school to college and progress in college. Students are paired with a dedicated coach starting as early as the spring of their senior year of high school and receive coaching through their first two years in college. As Boston's citywide college completion initiative, Success Boston partners with existing nonprofit organizations focused on coaching and mentoring to deliver these one-on-one coaching services. Nonprofit coaching partners may also provide students with other direct services such as tutoring and career readiness support, and financial support that includes scholarships, transportation subsidies, and funding for school-related materials and supplies. Findings on "Success Boston Coaching" from two studies that meet What Works Clearinghouse (WWC) standards are shown in this report. This intervention snapshot provides a brief summary of the full report. [For the Intervention Report, see ED608188. For the Intervention Brief, see ED608189.]
