A 'LEARNING DISABILITY' IS DEFINED AS 'A SUBSTANTIAL DEFICIENCY IN A PARTICULAR ASPECT OF ACADEMIC ACHIEVEMENT BECAUSE OF PERCEPTUAL OR PERCEPTUAL-MOTOR HANDICAPS, REGARDLESS OF ETIOLOGY OR OTHER CONTRIBUTING FACTORS.' THIS STATE-OF-THE-KNOWLEDGE REVIEW ENTAILED A THREE-TIERED APPROACH; A SURVEY OF THE EXISTING LITERATURE, RESEARCH ON CURRENT THEORETICAL DEVELOPMENTS, AND AN INVENTORY OF THE EXISTING PRACTICAL APPLICATIONS (DEMONSTRATION PROJECTS). THIS SUMMARY TURNS FIRST TO A DEFINITION OF LEARNING DISABILITIES, THEN TO THE EVIDENCE LINKING LEARNING DISABILITIES WITH DELINQUENCY, AND CONCLUDES WITH A REVIEW OF THE FINDINGS AND RECOMMENDATIONS IN THE FULL REPORT, NCJ-36635. A BRIEF OVERVIEW OF THE TERMINOLOGY AND ISSUES SURROUNDING LEARNING DISABILITIES IS APPENDED. (AUTHOR ABSTRACT MODIFIED)
