This article originates from our doctoral research that focuses on the relationships between thoughtful professional practices and educational wellbeing among high school teachers. This study focuses on the contribution of Q methodology to the exploration of high school teachers’ reflections on their professional practices. Thus, 13 teachers were asked to rank 14 statements on an answer sheet, according to their level of agreement with the contents thereof. The storage of the participants was analysed using the softwares QDA Miner and PQMethod. Our results suggest that the Q methodology can be considered a useful tool for the study of teachers’ reflections on their professional practices.
