Under Title 3 of the Older Americans Act of 1965, as amended, state and area agencies on aging are required to provide for the establishment or maintenance of information and referral services in sufficient numbers to assure that all older persons in the state or within a planning and service area will have reasonably convenient access to such services. This study is an evaluation of information and referral services (I and Rs). The focus is on key organizations involved in the planning, coordination and service delivery aspects of information and referral. Twelve substantive areas are evaluated by this study: (1) organization and facilities; (2) resource file; (3) staffing; (4) access; (5) interviewing, information-giving and referral; (6) publicity and outreach; (7) records and reports; (8) follow-up; (9) escort and transportation services; (10) planning; (11) coordination; and (12) funding and costs. The last chapter of this evaluation report provides recommendations based on objectives and findings of the study. (Author/JL)
