DATA WERE GATHERED ON THE UNCONSCIOUS MOTIVES OR PURPOSES IN THE CHOICE OF TEACHING AS A CAREER. THEY WERE USED AS A MEASURE IN PREDICTING POTENTIAL AND INDIVIDUAL TEACHING SUCCESS IN ELEMENTARY EDUCATION. SKETCHES OF MOTIVATIONAL TYPES ENCOUNTERED AMONG TEACHERS WERE DEVELOPED AND SAMPLED AMONG REPRESENTATIVE INDIVIDUALS OF EACH TYPE. THE INFORMATION COLLECTED FROM THIS GENERAL SAMPLE PROVIDED A BASIS FOR BUILDING OBJECTIVE DIAGNOSTIC INSTRUMENTS FOR THE IDENTIFICATION OF 10 MOTIVATIONAL TYPES. TESTS MEASURING ATTITUDE AND ROLE WERE ADMINISTERED TO APPROXIMATELY 150 TEACHER-TRAINEES AND PRACTICE TEACHERS TO DETERMINE GIVEN TYPES OF INDIVIDUAL MOTIVATION. ITEM ANALYSIS IN EACH OF THE TWO SAMPLES REVEALED SATISFACTORY DISCRIMINATIONS FOR EACH MOTIVATION CONSIDERED. SUITABLE INSTRUMENTS WERE THUS DEVELOPED FOR ASSESSING UNCONSCIOUS FACTORS IN CAREER MOTIVATION AMONG TEACHERS AS RELATED TO THE ELEMENTARY SCHOOL TEACHING PROCESS. (JH)
