IT REPRESENTS FIRST AN ATTEMPT TO ASSESS THE ADEQUACY OF THE CLASSIFICATION SYSTEM OF WARDS WHICH HAS TRADITIONALLY EMPHASIZED EDUCATIONAL GOALS. SECONDLY, IT SEEKS TO IDENTIFY SPECIFIC FACTORS IN PERSONAL HISTORIES, TRAINING SCHOOL EXPERIENCES, AND PLACEMENT AFTER TRAINING SCHOOL WHICH MAY BE ASSOCIATED WITH HIGHER OR LOWER LEVELS OF ADJUSTMENT. DATA ON 464 WARDS FIRST ADMITTED DURING THE 1966-67 FISCAL YEAR TO 5 TRAINING SCHOOLS ADMINISTERED BY THE PROVINCE OF ONTARIO WERE COLLECTED FROM MAIN OFFICE FILES. THE DATA INCLUDED ALL CONSISTENTLY AVAILABLE INFORMATION POTENTIALLY RELATED TO, OR PREDICTIVE OF, POST-INSTITUTIONAL ADJUSTMENT. DATA WERE ORGANIZED INTO THREE TIME PERIODS: PRE-, INTRA-, AND POST-INSTITUTIONAL EXPERIENCES OR BEHAVIOR PATTERNS. POST-INSTITUTIONAL ADJUSTMENT WAS MEASURED IN TERMS OF THE NATURE OF MOST RECENT LIVING SITUATION (CURRENT STATUS), EMPLOYMENT AND EDUCATIONAL PERFORMANCE (WORK/SCHOOL), AND FURTHER DELINQUENCY OR CRIMINALITY (BEHAVIOR). THESE MEASURES WERE ALSO COMBINED INTO AN INDEX OF OUTCOME WITH EACH POSSIBLE OUTCOME RATED BY DEPARTMENTAL PERSONNEL AND LABELLED GOOD, ACCEPTABLE, AND UNFAVORABLE. VARIABLES RELATED TO EACH LEVEL OF OUTCOME WERE SOUGHT AND EXPLORED IN DEPTH, THE FOCUS BEING THE IDENTIFICATION OF BEHAVIOR PATTERNS AND POSSIBLE INTERVENING INFLUENCES. MANY STATISTICAL TABLES ARE INCLUDED. (AUTHOR ABSTRACT)...MSP
