This paper explores the future potential of informal learning for leadership development in the nonprofit sector through the experience of the Centre for Voluntary Sector Leadership (CVSL) at the Open University, UK. From its inception in 2016, CVSL developed learning outside the mainstream curriculum, providing open access informal learning opportunities to increase access to leadership development for practitioners in smaller nonprofit organizations. Our experience of developing and delivering this learning has encountered challenges related to institutional, sector, and policy contexts. Despite these challenges, we argue that HE-provided informal leadership learning has the potential to address issues of accessibility, timeliness, and relevance for smaller nonprofit organizations. The paper reflects on the future role of informal learning as part of an “ecosystem” of nonprofit leadership development in a volatile and marketized environment.
