This study was conducted with the participation of 33 pre-service teachers attending the department science teaching of a Turkish university. Participants self-reported using the "Self-assessment of creativity scale" and were asked to choose the most appropriate answer to the five-choice self-assessment question "Which category best describes your creative scientific thinking skills?" The main problem of the study concerns pre-service science teachers' self-assessments of their creative thinking and creative scientific thinking skills. The findings of the study showed that pre-service teachers were sometimes uncertain about their creative thinking skills, and saw their scientific creativity as only partially satisfactory.
