This article presents the results of research examining an innovative initiative designed to build capacity for international, collaborative scholarship of teaching and learning: the development of international collaborative writing groups (ICWG). The study focusses particularly on the role of leadership within the groups as a significant factor in the effectiveness of the initiative. Results from an online survey of 30 former ICWG-participants reaffirm the significance of leadership to the ICWG's success. In particular, respondents emphasise the value of leadership approaches that foster community and encourage members to take responsibility for tasks. Implications for leadership in related academic development contexts are considered.
