Results of a study of secondary school teachers in Tawian suggest that a high school graduate's interest in teaching when he applies for university admission may not be correlated with his performance in teaching afterward. The study covered 331 secondary school teachers who graduated from National Taiwan Normal University, a teacher training institution. Approximately half of these teachers listed attending a department of this university as their first choice when they took the Joint Entrance Examination for all universities in Taiwan. The other teachers entered Taiwan Normal University only because they were not admitted to the college department they preferred. Results of intergroup comparisons showed that the first choice group did no better than the others in undergraduate academic achievement or in professional knowledge of education, nor did they perform better in classroom teaching, as rated by their principals. Moreover, the two groups of teachers did not differ in their subjective satisfaction with teaching. A second study suggests that the training program provided by a training institution can help develop the interest and knowledge in teaching among those who do not have a strong desire in teaching to begin with.
