This Guide is designed to support the work of institutional cross-functional teams charged with strengthening adjunct faculty professional learning and institutional engagement. Each section shares key learnings from ATD's work with six Leader Colleges, including accomplishments in the form of new programs, services, or policies that can serve as examples for your college to adapt in a way that will fit authentically in your institution's culture. Our goal here is to help college teams anticipate obstacles and barriers, understanding that the relationship-building work necessary to overcome these challenges very often facilitates success in other related work. Each section of the Guide also includes tools in the form of worksheets and planning templates to support your team's efforts.
