Which groups were involved in the development of the concept?

Initial leadership was taken by the National Occupational Information Coordination Committee (NOICC) through its Career Development Training Institute (CDTI) which had representatives from 15 associations on its Board. Through a CDTI grant to Oakland University, Howard Splete, Judy Hoppin and others developed  competencies and an instructor training curriculum. Later various groups worked with CCE/NBCC to develop requirements for the GCDF credential. These organizations, including the National Career Development Association, the National Employment Counseling Association, and the National Association of Workforce Development Professionals, endorsed the GCDF credential.
