This book was developed to help administrators meet the challenge of compliance with the regulations implementing Section 504 of the Rehabilitation Act of 1973. All colleges, universities, and other organizations that are funded by the Department of Health, Education, and Welfare (HEW) have until June 3, 1980, to make structural modifications necessary to make their programs fully accessible to handicapped persons. Programs are to be accessible now in all cases in which structural modifications are not necessary. Nine chapters and an introduction trace the steps in developing a program for accessibility, from understanding what constitutes a barrier in the built environment to specific recommendations on site and building design and design of science laboratories. The functional relationships between various disabilities and the use of the environment are described. Design requirements associated with these functional relationships are described and illustrated. State of the art information about instructional aids is broken down into three groups: instructional aids for the mobility impaired, aids for students with sight disabilities, and aids for students with hearing disabilities. The final chapter discusses resource and funding sources. (Author/MLF)
