Social diversity is now commonplace in many communities in today's globalised world. This diversity can be seen in any classroom of learners, and international studies have shown the complex ways in which disabilities, race, ethnicity, gender and social class can determine a child's opportunity to succeed or fail in the education system. In Hong Kong, like in many educational contexts around the world, teachers are grappling with increasing diversity amongst their students, including teaching students with special educational needs (SEN) and non-Chinese speaking students (NCS) living in Hong Kong. This paper examines how three primary TEFL (Teaching English as a Foreign Language) teachers are constructing identities as inclusive practitioners as they grapple with enacting the inclusive education policy recently introduced into Hong Kong schools. The data are drawn from a small-scale collaborative reflective inquiry for teacher professional development. Drawing upon a sociocultural and critical framing of identity theory, we trace the three teachers' identity construction as EFL teachers and inclusive education practitioners. We view the role of discourse, self-positioning and social context as key processes in teacher identity formation. Implications for furthering the development of inclusive education in EFL classrooms are offered.
