In the context of language education, teacher personalities play a crucial role in shaping the learning environment, influencing student interaction, instructional methods, and the overall learning experiences. This qualitative study, employing semi-structured interviews as primary data collections tools, represents an attempt to explore students’ attitudes towards their teachers with distinct DISC personality profiles: Dominance (D), Influence (I), Steadiness (S), and Conscientiousness (C). The reflexive thematic analysis of the interview data revealed a range of student responses, including both positive and negative attitudes. The participants’ openness in expressing their views offered rich insights into these contradictory perceptions, some of which were unexpectedly revealing. These informative findings underscore the importance of understanding students’ attitudes in relation to long-term language learning and highlight how teachers’ DISC personalities can significantly affect students’ emotions, engagement, and motivation. This study contributes to a more holistic understanding of student-teacher dynamics in language education by offering in-dept insights into the influence of DISC personality traits among teachers.
