Part of a study of the link between learning disabilities (LD) and juvenile delinquency (JD), the paper reviews definitions and treatment principles. An introduction reviews definitions of the federal government (in regulations for P.L. 94-142, the Education for All Handicapped Children Act), of the Association for Children and Adults with Learning Disabilities, of laymen, and of the LD/JD project. A glossary is then presented along with a list of common manifestations of LD. A section on treatment decisions notes the indicators of LD, the rights and needs of LD youths, and treatment alternvatives. This is followed by a description of two alternative programs--an academic treatment approach using task analysis and a life skills training program focusing on getting and keeping a job and moving toward independent living. Appended material includes identification and medical history forms. (CL)
