A 1-YEAR PILOT STUDY SCREENED 1,200 NAVAJO INDIAN CHILDREN ENROLLED IN INDIAN BOARDING SCHOOLS OF SAN JUAN AND SHIPROCK, NEW MEXICO. A TEACHER REFERRAL FORM USED FOR INITIAL SCREENING LOCATED 56 CHILDREN BETWEEN THE AGES OF 7 AND 14. INDIVIDUAL BEHAVIOR PROFILES WERE PREPARED FROM PSYCHOLOGICAL AND MEDICAL EVALUATIONS AND SOCIAL HISTORIES. THIRTY-FIVE CHILDREN WERE JUDGED TO BE EDUCABLE MENTALLY RETARDED, AND 15 CHILDREN WHO HAD OTHER HANDICAPPING CONDITIONS NOT RELATED TO MENTAL RETARDATION WERE REFERRED TO OTHER AGENCIES. THREE CHILDREN WHO WERE DIAGNOSED AS BEING SEVERELY RETARDED, BRAIN INJURED, AND EMOTIONALLY DISTURBED WERE REFERRED TO A RESIDENTIAL HOSPITAL. THE REMAINING THREE WERE CONSIDERED NORMAL CHILDREN AND INAPPROPRIATE REFERRALS. PLANS WERE MADE FOR FOUR SPECIAL CLASSES OF 10 CHILDREN EACH TO BEGIN IN SEPTEMBER 1965. TEACHERS WERE TO RECEIVE SPECIAL TRAINING. RECOMMENDATIONS BASED ON THE STUDY ARE MADE. AN APPENDIX CONTAINS THE TEACHER REFERRAL FORM, SOCIAL HISTORY OUTLINE, STAFF DIRECTORY, STANFORD ACHIEVEMENT TEST DATA, ESTIMATED COST OF STUDY, AND THE DIAGNOSTIC SUMMARY AND INSTRUCTIONAL CLASSIFICATION FOR TWO OF THE CHILDREN.
