A SCALE TO MEASURE THE LEVEL OF OCCUPATIONAL ASPIRATION (LOA) OF SECONDARY SCHOOL STUDENTS AS A PREDICTIVE TOOL IN FUTURE OCCUPATIONAL CHOICE IS PRESENTED AND EXTENSIVELY EVALUATED IN THIS MONOGRAPH. THE OCCUPATIONAL ASPIRATION SCALE IS AN EASILY ADMINISTERED INSTRUMENT WHICH FOCUSES ON IDEALISTIC AND REALISTIC EXPRESSION LEVELS AS WELL AS ON SHORT RANGE AND LONG RANGE TIME GOAL PERIODS. EMPIRICAL DATA PRESENTED SHOWS THAT THE PREDICTED CORRELATIONS IN THE LOA CONCEPT ARE BORNE OUT 80 PERCENT OF THE TIME WHILE PREDICTED NONCORRELATES ARE FOUND TRUE 70 PERCENT OF THE TIME. HYPOTHESES ABOUT THE BEHAVIOR OF LOA INCLUDE HIGH POSITIVE CORRELATIONS BETWEEN (1) LOA AND SUBSEQUENT LEVEL OF OCCUPATIONAL ACHIEVEMENT, (2) LOA AND ANY MEASURE OF SUCCESS IN SCHOOL, (3) LOA AND ANY PERSONAL ORIENTATION TENDING TO PRODUCE THE EXPERIENCE OF SUCCESS, (4) LOA AND ANY PERSONAL ORIENTATION EXPRESSING THE WILLINGNESS TO ACT INDEPENDENTLY, (5) LOA AND THE DEGREE TO WHICH THE SOCIAL STATES OF THE PERSON TENDS TO PRODUCE SUCCESS IN OCCUPATIONALLY RELATED AREAS OF BEHAVIOR, (6) LOA AND THE SUCCESS ORIENTATIONS OF THE GROUP TO WHICH THE STUDENT BELONGS, AND (7) LOA AND SELF-CONCEPTIONS CONCERNING SUCCESS OR ACHIEVEMENT ORIENTATION. IT IS FELT THAT, ALTHOUGH MORE TESTING OF ITS PREDICTIVE VALIDITY AND FURTHER SAFEGUARDS AGAINST STUDENT FAKING ARE REQUIRED, THE OCCUPATIONAL ASPIRATION SCALE IS A SATISFACTORY INSTRUMENT FOR RESEARCH ON LOA AND MAY BE ESPECIALLY USEFUL TO VOCATIONAL COUNSELORS.
