Presented is the interim report on a comprehensive plan for the education of handicapped children in Ohio which was requested by the state legislature at the time of the passage of Subcommittee Senate Bill 405 (Sub. S.B. 405). Introductory chapters attempt to place Sub. S.B. 405 in historical perspective by examining the development of special educational programs and services in Ohio; a 1970 document discussing long range planning goals for special educational services in Ohio; and services provided by regional resource centers from 1967 through 1973. Major provisions of the bill and plans for its implementation are discussed briefly. The interim report examines the present status and projected needs of programs for the hearing impaired, visually handicapped, orthopedically handicapped, deaf/blind, learning disabled, emotionally disturbed, educable mentally retarded (EMR), and speech, hearing and language impaired (definitions of each handicapping condition are included). Present status and projected needs are also indicated for services such as home instruction, supplemental tutoring, and transportation; facilities; and manpower. Estimated costs of the programs and services are included. The report concludes with preliminary recommendations concerning such issues as interdistrict cooperation, transfers for trainable mentally retarded children, early assistance, new special education units, and vocational opportunity for handicapped children.
