This study investigated the longitudinal changes in the attitudes of pre-service primary education teachers towards the teaching profession as they progressed through training. The results indicate that there is a significant difference in pre-service teachers' attitudes towards the profession between their freshman and senior years. Moreover, the findings obtained through interview data have shown that both positive and negative changes occur in pre-service teachers' attitudes towards teaching throughout their education, and these changes are observed to be related to teaching practice, cooperating teachers, teacher education institutions and teacher educators.
