This book examines internationalization practices, policies and experiences within TESOL teacher education. The chapters offer empirical, conceptual and theoretical engagements with the internationalization of TESOL teacher program curricula from both global and critical perspectives. They analyze the opportunities, challenges and gaps between internationalization policy, practice and international activities through the intersectional voices of researchers, teacher educators, students and pre- and in-service teachers of English in diverse settings. In doing so, this book identifies the trends, skills and knowledges needed for, or developed through, the internationalization of TESOL teacher education while also contributing to the decolonialization of the field.
