This paper provides an overview and description of the Certificate of Advanced Graduate Study (CAGS) program in professional development in public schools offered at Fitchburg State College (Massachusetts). The CAGS provides opportunities for people in the same school system to develop knowledge, skills, and teaching methodologies to work with adult learners; goals are tailored to each specific community; and staff development experts are created in the school system. The certificate enables veteran master teachers, specialists, and administrative staff to develop competence in the areas of organizational development, planned change, the design, delivery, management and evaluation of staff development programs, and action research to address the needs and goals of a school system. Thus the system is empowered to restructure through the collaborative efforts of all. Also described is the subsequent establishment of the Professional Development Center, which offers support to the goals of area school systems. Workshops, professional seminars, long-term networks, and consultation services enhance the quality of educational services and create a mutually rewarding relationship between the college, the community, and the individuals served.
