THIS STUDY COMPARED COUNSELOR PREDICTIONS OF COLLEGE ACHIEVEMENT AND LEADERSHIP PARTICIPATION IN EXTRACURRICULAR ACTIVITIES IN A GROUP OF UNDERGRADUATE COLLEGE STUDENTS. COMPARISONS WERE MADE BETWEEN 3 GROUPS OF COUNSELORS AND ONE GROUP OF NON-COUNSELORS TO IDENTIFY CHARACTERISTICS OF GOOD CLINICAL PREDICTORS AND TO COMPARE EFFICIENCY OF CLINICAL AND ACTUARIAL METHODS OF PREDICTION MAKING. CRITERION DATA INCLUDED FRESHMAN GRADES, 4-YEAR GRADE AVERAGE, MAJOR FIELD OF STUDY, GRADUATION VERSUS NONGRADUATION, AND RECORDS OF PARTICIPATION IN STUDENT ORGANIZATIONS. RESULTS ARE DELINEATED UNDER THE SUBHEADS OF (1) ACADEMIC ACHIEVEMENT PREDICTIONS, (2) MAJOR PREDICTIONS, AND (3) LEADERSHIP ACTIVITY PREDICTIONS. (LP)
