The study explored the desirable character attributes of teachers and provided specific behavioral guidelines for being a good teacher in Korea. The Delphi method was used. Ten virtues and 88 behavioral guidelines were created from three rounds of surveys involving 22 Korean panelists. Results indicated that most of the virtues identified in this study were consistent with the results of Western studies. However, a sense of humor regarded as a desirable characteristic of teachers in previous studies did not emerge as a virtue from Korean panelists. Morality rarely mentioned in Western research was included in this study. The characteristics required of a Korean teacher seem to be based on Confucianism.
