The design of an evaluative study of a program for providing information and referral services (I&R) through a coordinated network of semi-autonomous I&R centers is described in this report. The program, implemented by the state of Wisconsin as a demonstration project from 1972-1974 was operated by the Division on Aging, Department of Health and Social Services. Its purposes were to provide for evaluative research into the usefulness of the I&R program to the elderly and other state residents seeking information regarding available human-services programs. This study includes a program description, project goals and research considerations, specific objectives and their underlying assumptions, criteria for determining the achievement of objectives, research strategy and methodology for evaluating the demonstration, and results of the evaluation. Appendices include forms and reports used in the I&R system: an I&R user survey with a user interview form and a structured interview for evaluation purposes, a summary of services delivered, and an I&R worker report.
