The spread of English as a global language has led to discussions and debates about English language teaching and whether language teacher education should prepare pre- and in-service teachers to teach English from the global Englishes (GE) perspective. This thematic review first addresses the need to move from traditional assumptions about native speakerism in language teaching and then links it to individual cognition in GE-informed teacher education. The review then presents cases of GE teacher education in various contexts and addresses challenges in and future directions for GE-aware teacher education. The implications for GE language teacher education from the perspectives of "looking inward," "looking around," and "looking forward" are discussed at the end of this review.
