With the increasing number of Chinese learners all over the world, the demand for Chinese teachers is increasing day by day. A high-level teaching staff is necessary to promote the long-term and stable development of international Chinese education. In order to improve the professional quality of the teachers, it is urgent to build a better international Chinese teacher training system. It is found that TESOL (Teaching English to Speakers of Other languages) teacher training model in the United States is relatively mature and has been highly recognized by English teachers and employers all over the world. An in-depth analysis of TESOL's training concepts, target students, training objectives, curriculum design and certification can help academic circles in China understand the characteristics of American TESOL programs, provide reference for international Chinese teacher training, and build a set of globally consistent standardized professional training model for international Chinese teachers.
