Most professionals have plenty of experience learning in classroom settings, through one-on-one instruction, or by accessing reference materials such as books, journals, and online content. Fewer have experience learning in a professional community setting where they are both learner and teacher at different times. Achieving the Dream is committed to the long-term goal of improving sustainable student outcomes through the transfer of effective practices between colleges. This Peer Learning Toolkit provides colleges with the basics on peer learning as well as tools and resources for designing and launching an effective peer learning community.
