Adopting and sustaining open science practices is accompanied by particular opportunities and challenges for faculty at small liberal arts colleges (SLACs). Their predominantly undergraduate student body, small size, limited resources, substantial teaching responsibilities, and focus on intensive faculty-student interactions make it difficult to normalize open science at SLACs. However, given the unique synergy between teaching and research at SLACs, many of these practices are well-suited for work with undergraduate psychology students. In addition, the opportunities for collaboration afforded by the open science community may be especially attractive for those doing research at SLACs. In this paper, we offer suggestions for how open science can further grow and flourish among faculty who work closely with undergraduates, both in classrooms and in labs. We also discuss how to encourage professional development and transform institutional culture around open science practices. Most importantly, this paper serves as an invitation to SLAC psychology faculty to participate in the open science community.
