In response to demographic changes and their impact on graduate higher education enrollment, universities are looking at innovative methods to increase enrollment, revise programs of study and improve instructional delivery systems. Institutions are attracting older adult students by altering admission policies, establishing adult student services offices, and offering course schedules that meed this population's need for flexibility. Executive education courses are one example of a service developed by institutions for a different population: managers and executives. Harvard Business School's Owner/President Management Program consists of three, 3-week sessions over 3 years. The demand for custom executive programs is rapidly growing. Graduate certificate programs are other educational program alternatives which focus on areas of specialized knowledge and are completed on a part-time basis. Distance education also serves the needs of diverse populations and utilizes the growth and sophistication of telecommunications technology. One example of world-wide distance education is the National Technological University which consist of a consortium of 29 universities and has developed a Management of Technology graduate program targeted at working professionals in industry with undergraduate technical degrees. Figures show estimated trends in master's and doctoral degree starts and completions from 1980 through about 2005. (Contains 24 references.) (JB)
