Book excerpt: This book explores ways to prepare teachers to teach English as an International Language (EIL) and provides theoretically-grounded models for EIL-informed teacher education. The volume includes two chapters that present a theoretical approach and principles in EIL teacher education, followed by a collection of descriptions of field-tested teacher education programs, courses, units in a course, and activities from diverse geographical and institutional contexts, which together demonstrate a variety of possible approaches to preparing teachers to teach EIL. The book helps create a space for the exploration of EIL teacher education that cuts across English as a Lingua Franca, World Englishes and other relevant scholarly communities.
