This study examined the effectiveness of self-assessment during teaching practice and determined whether the students, after engaging in the self-assessment process, exhibited changes in their learning and teaching. Participants comprised 47 students who were enrolled in an in-service teacher education program. Questionnaire and focus group interviews were employed to examine the usefulness of the self-assessment and the possible changes in students' learning. Analysis of the results indicates that students found that self-assessment enhanced their learning during teaching practice, especially in the area of reflective thinking.
