Are all the teachers in international schools foreign teachers?

No, there are also teachers from China. Only the proportion of foreign teachers in international schools is larger than that in ordinary schools. When recruiting teachers in international schools, in order to ensure the excellence of teachers, foreign teachers are recruited through some internationally recognized recruitment agencies, which ensures the quality of these foreign teachers. School leaders also go abroad to attend some job fairs every year and recruit a group of high-quality teachers when attending foreign job fairs. Every time you recruit a teacher, ensure that everyone is a teacher with a national teacher qualification certificate. When recruiting teachers from China, they are all teachers from education majors, and some are old teachers with rich teaching experience, which ensures the quality of recruiting teachers.
