Communities of Practice: Becoming a Teacher

Etienne Wenger's (1998) theory of Communities of Practice provides another useful way of understanding the purpose of ending mentoring.

Wenger argues that professional learning is not simply about acquiring knowledge or developing skills. It is also about developing a professional identity through participation in a community.

When trainees begin their placement, they enter the school as newcomers. They observe experienced colleagues, participate in professional discussions and gradually assume greater responsibility for teaching. Wenger describes this progression as moving from 'legitimate peripheral participation' towards fuller participation within a professional community (Lave & Wenger, 1991).

The progression image shown from the previous page reflects this journey. Initially, trainees require significant support from experienced colleagues. They learn by observing, practising, receiving feedback and reflecting upon their experiences. Gradually, however, they begin contributing more confidently to the professional community. Their conversations become increasingly analytical, their judgements become more secure and they begin taking ownership of their own development.

Mentoring plays a central role in facilitating this transition. Throughout the placement, the mentor acts as an experienced member of the profession, helping the trainee understand not only how to teach, but also what it means to think, act and behave as a teacher. As the mentoring relationship progresses, the mentor's role also evolves. Rather than providing continuous direction, they increasingly become a professional colleague who validates thinking, offers challenge where appropriate and supports continued growth. The conclusion of mentoring therefore represents far more than the end of a placement.

It marks a significant shift in professional identity. The trainee is no longer simply learning to become a teacher. They are beginning to see themselves as a teacher.
