This participant's manual covers "Systems and Policies," the third module of a four-module training program for all individuals employed in programs funded by Oklahoma's Developmental Disabilities Services Division. This includes van drivers, recreation workers, residential staff, administrators, case managers, secretarial/clerical staff, vocational staff, advocates, physicians, psychologists, and others. The primary objective of the module is to have the participant understand the system that shapes service delivery in Oklahoma for people with developmental disabilities. Secondary objectives focus on specific services provided and people responsible for delivering those services, basic services provided by state employees and private provider agencies, members of interdisciplinary teams, elements of successful habilitation programs, and the process an interdisciplinary team goes through in developing an individual plan. The module includes the primary and secondary objectives, a text and question format that allows participants to become actively involved in the learning process, information from transparencies used in training, and copies of handouts.
