In this account of practice, the authors introduce a variant of classic action learning, called developmental action learning (DAL). The DAL model, derived from cognitive development theory, introduces conventional learning modules prior to the more intensive set experience. It also calls for facilitation designed to help participants, selected for their readiness to change, make the leap to deeper levels of personal and organizational development. The DAL approach is applied to a leadership development series among a group of high-level administrators within a university consortium. The case study gives promise to the use of developmental action learning to enhance collaborative leadership processes. (Contains 1 table and 1 figure.)
