This manual explains how to administer the Life Career Development Needs Survey(s) for adults and suggests ways to use the data obtained. Three separate needs surveys are included for the following segments of the adult population: young adult, middle adult, and older adult. The instruments are based on three domains of career development needs: interpersonal effectiveness; work and life skills; and life career planning. These domains represent major spheres of concern in the Georgia Comprehensive Career Guidance Project's life career development model. (See ERIC document CE 019 692 for a detailed description of the career guidance model for postsecondary and adult programs; ED 160 850 describes the elementary and secondary career guidance model.) Other related documents contain the administration manuals for the following: the Life Career Development Needs Survey for elementary students (CE 019 697) and secondary students (CE 019 698); guidance program assessment instruments for elementary schools (CE 019 694), secondary schools (CE 019 695), and postsecondary and adult programs (CE 019 696); and three community survey instruments (CE 019 693).
