In this study, the first objective was to identify the personality pro
files of 4,483 participants in an early teaching experience program wh
o eventually either continued or discontinued their preparation to bec
ome teachers, The second objective was to identify the personality typ
es of 886 students who completed their preparation to teach as a funct
ion of their area of certification (elementary, secondary, etc.), Meas
ures on the Myers-Briggs Type Indicator (MBTI), augmented in the first
analysis by a dichotomous continue/discontinue variable, and in the s
econd analysis by four areas of certification, were subjected to confi
gural frequency analyses (CFA) for the purpose of identifying discerni
ble personality types and antitypes, Results indicated that the S-F-J
profile on the MBTI described a significant number of students who con
tinued in education, Also identified were several types and antitypes
linked to areas of teacher certification, Implications for education i
n this decade of reform are discussed.
