Seeing the significance of exploring associate teachers' views about teaching practicum, this qualitative case study aims to seek answers to the questions of what the selfperceived roles of four Turkish associate teachers in teaching practicum are and what their perceptions concerning the adequacy of the length of teaching practicum in Turkey are. Additionally, the present research targets finding answers to the questions of whether teaching practicum contributed to the professional development of the last trainee teachers the associate teachers have mentored and if mentoring fosters their own professional development. The results indicated they considered offering professional and emotional support to trainee teachers as their pivotal roles in teaching practicum and the length of teaching practicum as insufficient. The findings also demonstrated that the associate teachers believed teaching practicum substantially contributed to the professional development of the last trainee teachers they had mentored and mentoring enhanced their own professional development.
