THE OBJECTIVE WAS TO EMPLOY TECHNIQUES OF PROFILE ANALYSIS TO DEVELOP THE JOINT PROBABILITY OF SELECTING A SUITABLE SUBJECT MAJOR AND OF ASSURING TO A HIGH DEGREE GRADUATION FROM COLLEGE WITH THAT MAJOR. THE SAMPLE INCLUDED 1,197 MIT FRESHMEN STUDENTS IN 1952-53, AND THE VALIDATION GROUP INCLUDED 699 ENTRANTS IN 1954. DATA INCLUDED SECONDARY SCHOOL GRADES, RANK AND TYPE OF SCHOOL ATTENDED, COLLEGE BOARD SCORES, INTENDED COLLEGE MAJOR AT TIME OF APPLICATION AND MATRICULATION, FIRST SEMESTER GRADES AT MIT (INDEPENDENT VARIABLES) GRADE AVERAGE AT MIT, COLLEGE MAJOR IN LAST SEMESTER OF ATTENDANCE, AND BACHELOR'S DEGREE EARNED (DEPENDENT VARIABLES). REGRESSION ANALYSIS WAS USED TO DERIVE A PREDICTION OF CHANCES FOR GRADUATION GIVEN MEMBERSHIP IN A PARTICULAR MAJOR. DISCRIMINANT ANALYSIS WAS EMPLOYED TO DERIVE THE PROBABILITY OF MEMBERSHIP IN A PARTICULAR MAJOR. THE CONCLUSIONS REACHED WERE THAT THE PROBABILITIES WOULD FAIL IN PASSING NEW AND RELEVANT INFORMATION TO THE STUDENT AS FAR AS HIS ACADEMIC SCORES ARE CONCERNED. (GC)
