This manual is designed to provide adolescents and young adults who have disabilities with a blueprint for setting and achieving goals, making decisions, acquiring needed supports, and achieving a self-determined and sustainable lifestyle. A planning process called Group Action Planning is used as a foundation for self-determination, with guidelines provided for establishing an Action Planning Group, choosing a facilitator, getting stakeholders and peers involved in the group, and conducting meetings. Techniques for brainstorming, goal-setting, decision making, conflict resolution, and negotiation are described. Common pitfalls of group planning for self-determination are diagnosed and solutions suggested, including problems of interpersonal chemistry, clashes between parents and the planning group, and uninspired leadership. A separate section of the manual is dedicated to celebrating successes, including anecdotes from individuals who have achieved their goals through the group planning method. A resource guide lists self-determination projects in 19 states, books, videotapes, articles, curricula, and national information and advocacy groups. (PB)
