This report analyzes the incidence of learning disabilities among individuals in Job Training Partnership Act (JTPA) and other employment training programs and the impact of these learning disabilities on programmatic approaches to functional literacy assessment and training. The report examines the proportion of target individuals likely to be learning disabled (LD), the state of the art for testing and assessing adults to identify learning disabilities, the state of the art with respect to providing basic and occupational skills instruction to learning-disabled persons, and local and national level actions needed to ensure that learning-disabled persons eligible for employment and training programs are properly served. The report concludes that 15 to 23 percent of JTPA Title II participants may be LD and 25 to 40 percent of other federal employment training participants may be LD. To diagnose the disability, comprehensive procedures are available which must be administered and interpreted by experienced, specially training professionals. Recommendations include combining basic skills instruction with functional occupational skill instruction and avoiding arbitrary referral of persons with low reading skills to possibly inappropriate remediation programs. Appendixes describe studies estimating literacy and functional literacy and studies estimating the LD population. A list of learning disability subtypes, informal learning disability checklists, resources for providing instruction to LD adults, and guidelines for providing work-related training to LD persons are also provided.
