The 2004 Council on Rehabilitation Education (CORE) standards were revised to include Human Growth and Development (HGD) as a knowledge domain. The HGD domain introduces a significant amount of new content to the curriculum, including several topics that have not traditionally appeared in the rehabilitation counselor educational curriculum. Thus, this domain presents both an educational challenge and an educational and professional opportunity. Our purposes in this article are to review the place of HGD in the CORE curriculum and in rehabilitation counseling practice; to describe the HGD knowledge domain and its educational outcomes; and to discuss educational perspectives on this knowledge domain in the preservice curriculum. We propose that the inclusion of the HGD domain provides an opportunity for improving professional practice and for exploring our current and future professional roles. (Contains 2 tables.)
