This study was an attempt to investigate the relationship between teachers' personality type (feeling vs. thinking) and speaking skill of pre- intermediate EFL students in Iranian context. Twelve teachers and forty eight students from a local language institute participated in the study. The Myers Briggs Type Indicator (MBTI), an instrument based on Jung’s personality theory, was taken from teachers and students were administered Preliminary English Test (PET) interview. SPSS was used to calculate the required analyses. The results showed a statistically significant positive relationship between teacher’s’ personality type and learners’ speaking skill. It was also indicated that there is a statistically significant difference between speaking skill of learners taught by feeling teachers vs. thinking teachers. In fact students in the feeling group had higher speaking scores than their counterparts in the thinking group.
