A Chicago suburban public school with approximately 450 children per grade level demonstrated a system-wide program for identification, diagnosis, and educational treatment of children with learning disabilities in grades 2 through 6. Children were judged to underachieve when achievement measures in language or mathematics fell more than 10% below the expected level based on age, IQ, and grade placement. During the 3 year project, a screening program was developed and employed with 2,300 children. A novel remedial program was carried out for 156 children. Specialists in learning disabilities refined the screening diagnosis and developed teaching prescriptions for all students. Much of the teaching was carried out by teachers with minimal special training. The procedures developed may be especially useful to districts initiating a learning disabilities program or one which is handicapped by lack of specially trained teachers. The report contains program description, measures of student performance, tables on incidence and types of learning disabilities, and suggestions for implementing a program. (Author/RJ)
