Learning as a central focus in the discourse on professional development is well grounded in the educational and professional development literature. Yet, despite this consensus, and significant research on how professionals learn, most professional development and continuing professional education (CPE) practices continue to focus on delivering content rather than enhancing learning. This paper provides an update and overview of adult education's ongoing critique of and contributions to debates about the aims, structure, and purposes of continuing professional development and CPE. The author profiles a long-standing and continuing effort by educational scholars to reclaim this vital area of study and practice, in order to bring their learning focus as well as their critical questions to bear on it.
