THIS REPORT SUMMARIZES SEVERAL STUDIES BY THE AUTHORS EMPLOYING A TWO-WAY CLASSIFICATION OF OCCUPATIONS DESCRIBED BY ROE IN 1956. USING A CODING-BY-EXAMPLE CLASSIFICATION, CLERKS ACHIEVED INTERRATER RELIABILITY OF .98 FOR GROUPS AND .92 FOR LEVELS. THESE OCCUPATIONAL CODINGS TYPICALLY CORRELATED MINIMALLY BUT UNIQUELY WITH ACADEMIC CRITERIA, CONTRIBUTING SIGNIFICANTLY TO MULTIPLE PREDICTION OF SUCH DISPARATE CRITERIA AS ARCHITECTURE SCHOOL SUCCESS, GRADUATION FROM LAW SCHOOL, AND GRADES IN FRESHMAN COURSE WORK. FURTHER, STUDENT RATINGS OF FATHER'S AND INTENDED OCCUPATIONAL GROUPS WERE FOUND TO BE SIGNIFICANTLY RELATED TO ACADEMIC PERFORMANCE. (AUTHOR)
