The study developed and tested a systematic format for discovering and displaying relationships among five major federal laws concerning the handicapped: P.L. 93-112 (Rehabilitation Act of 1973), P.L. 93-380 (Education Amendments of 1974), P.L. 94-63 (Special Health Revenue Sharing Act of 1974), P.L. 94-103 (Developmentally Disabled Assistance and Bill of Rights Act), and P.L. 94-142 (Education for All Handicapped Children Act of 1975). The study examined the statutes themselves, the legislative history to discover Congressional intent, and how the laws have been incorporated into the U.S. Code. A chart depicts the preceding laws which were amended by the five laws studied and the subsequent laws which have amended these five laws. The report is in three sections. The first presents a brief historical overview of the law with a summary of each law and an explanation of the topics reviewed. The next section presents an indepth review of the five laws by topic with excerpts of the relevant texts. The final section delineates results, conclusions, and observations related to the laws and gives recommendations for further study. A narrative summary and table comparing the laws is provided for the following topic areas: eligibility criteria, services provided, procedural safeguards, and individualized written programs. (DB)
