A PROJECT WHICH DEVELOPED A "DESIGNED EDUCATIONAL ENVIRONMENT" TO IMPROVE THE ACADEMIC ACHIEVEMENT OF DELINQUENT ADOLESCENT BOYS IS DESCRIBED. BASED ON THE BEHAVIOR THEORY OF LEARNING, THE PROJECT OFFERED 16 INSTITUTIONALIZED BOYS VOLUNTARY DAILY PROGRAMED OR SEMI-PROGRAMED ACADEMIC COURSES. CURRICULUMS WERE CREATED FOR EACH STUDENT ON THE BASIS OF HIS SCORE ON A PRETEST. TO RECEIVE THE EXTRINSIC REINFORCEMENTS (GOODS OR SOCIAL REINFORCERS), WHICH WERE AVAILABLE ONLY THROUGH POINTS EARNED BY ACADEMIC SUCCESS, EACH STUDENT WAS REQUIRED TO ACHIEVE A 90 PERCENT CORRECT GRADE ON AN INSTRUCTIONAL UNIT. THESE POINTS WERE CONVERTIBLE INTO MERCHANDISE, ADMISSION TO THE LOUNGE, AND PRIVATE STUDENT OFFICES. EACH STUDENT'S EDUCATIONAL BEHAVIOR WAS CONTINUALLY MEASURED TO EVALUATE THE EFFICACY OF THE PROGRAM'S PROCEDURES AND TO INDICATE TO THE STUDENT HIS OWN PROGRESS. FROM THIS INFORMATION LEARNING CAN BE TRANSLATED INTO THE DISCRETE BEHAVIORS WHICH CONSTITUTE IT, AND PROCEDURES CAN BE DEVELOPED TO ELICIT A CERTAIN BEHAVIOR TO INCREASE THE LIKELIHOOD THAT OTHER SIMILAR BEHAVIORS WILL OCCUR AND THAT LEARNING IN GENERAL WILL BE MAINTAINED. INCLUDED IN THIS REPORT OF THE PROJECT ARE A DISCUSSION OF THE PRINCIPLES OF BEHAVIORAL "ARCHITECTURE" AND PSYCHOLOGY UPON WHICH THE PROGRAM IS BASED AND A DESCRIPTION OF THE PROJECT'S ORGANIZATION, INCLUDING INFORMATION ABOUT THE ACADEMIC COURSES OFFERED. ONE SECTION DISCUSSES A TRAINING COURSE WHICH WAS DEVELOPED FOR THE STAFF AND ANOTHER CONTAINS COMPARATIVE DATA AND INFORMATION ON THE STUDENTS' EDUCATIONAL AND LEISURE BEHAVIORS.
