For study, results of survey from 607 people of parents of developmental disabilities were analyzed. First of all as a result, the most urgent issue to solve for lifelong education support of developmental disabilities if lifelong education center is to be established, was about three kinds of roles; role as a professional education center for people with developmental disabilities, role as a support for them to live independently in their region, and role as a professional education center for severe developmental disabilities only. Secondly, as a method of center establishment, equipping separate lifelong education facility for people with developmental disabilities and issues about selecting ideal management body were high in ranking. Third, users of the center must be limited to developmental disabilities by degree, and types of their disabilities. However, opinion about limiting users into severe disabilities only received large number of opposition. Lastly, as the main business areas that center has to concentrate were about supplying lifelong education program for developmental disabilities and finance support. Furthermore, for the direction of management, the highest ranked opinion was about developing exclusive program for developmental disabilities only, on the other hand, developing program for both general people and developmental disabilities was demanded in quite large amount of survey. Based on the study result above, management direction of lifelong education center for people with developmental disabilities and vitalization of lifelong education for them were discussed.
