Guidelines are provided for analyzing the content of the various Federal/State plans specifically mentioned in the Developmental Disabilities Services and Construction Act (PL91-517). A Federal/State plan and the relevance of State plan review of the planning process are explained. State plan review is shown to be an important tool for assessing availability of services for the developmentally handicapped under certain federally assisted programs in the state. State plans are discussed in terms of standards, coverage, eligibility, and scope of services. Necessary legal, fiscal, and administrative information is given. Eleven federally assisted programs requiring a State plan under the Developmental Disabilities Act are described in terms of legal, fiscal, and administrative authority, scope of service provisions, quality of service provisions (mandated federal standards), and extent of service provisions (eligibility criteria for service). Programs are reviewed from the Federal side only, based on Federal Law and regulations, and are intended to serve as basic roadmaps from which States may initiate their own Federal/State plan review. An Addendum includes recent Federal legislation affecting Federally assisted programs requiring a State plan. (Author/KW)
