The document introduces the Teaching Knowledge Test (TKT), which tests candidates' knowledge of language concepts, language use, and the background and practice of language teaching. The TKT consists of three modules that can be taken together or separately, with each module containing 80 objective questions. No teaching experience or qualifications are required to take the TKT, but candidates should have at least an intermediate level of English. The TKT Course aims to introduce readers to key teaching concepts, examine teaching approaches and activities, share resources for teachers, and provide opportunities for professional development. The TKT Course is intended for anyone looking to take or prepare for the TKT, those in teacher training programs, and teachers looking to improve their knowledge.
