"Three Big Lessons in Six Years" is both a reflection on the past and a look ahead to the future at Charlestown (C-Town) High School (Boston, Massachusetts) and other early college programs across the country. The purpose of this series is to document essential design elements, operational structures, and critical support for students to be successful. It also presents an authentic view of the troubleshooting required to overcome key initial challenges. The lessons--"Set a Vision to Guide the Future" (ED614773), "Build a Framework That Allows for Structure and Flexibility" (ED614782), and "Build a 'Both/And' Team"--represent three integral parts of C-Town Pathways' journey. Launching a successful early college program requires a dedicated team that can both create a vision for the program and keep that program running through day-to-day challenges, ensuring its success. This report, the third of the three lesson reports, shares lessons from the C-Town Pathways early college program--a partnership between Charlestown High School (CHS) and the nearby Bunker Hill Community College (BHCC), supported by JFF--about how to build a "both/and" team that can ensure the success of the partnership between institutions and, even more important, ensure student success.
