To obtain the certificate of international Chinese teacher, you must have a bachelor's degree. If you have a college degree, you can't get an international Chinese teacher's certificate. Academic certificates need to be uploaded when they are collected.
There is an interview when obtaining this certificate, so it is required to master a foreign language, not necessarily English. If you want to get an international Chinese certificate, you must ensure that your Mandarin reaches the second level.
The international Chinese certificate was issued by Kaohan, not by the Ministry of Human Resources. However, because Kaohan and Confucius Institute select a group of public teachers every year, having an international Chinese teacher certificate is a plus item.
Test of teaching Chinese as a foreign language;
The full name of the Chinese as a Foreign Language Teacher Qualification Examination is the Chinese as a Foreign Language Teaching Ability Examination, which is the earliest and most authoritative Chinese as a Foreign Language Teacher Qualification Examination. It is managed by the International Office of China Language and Literature Committee, a unit directly under the Ministry of Education of China (Hanban). Unfortunately, the national examination stopped in 2005, and it didn't resume until this year.
There is no limit to learning the sea. As long as you study hard, you can learn knowledge anywhere. As for the role of the certificate, I believe it is also linked to personal ability. Whether the certificate is useful or not is a matter of different opinions, but whether the knowledge and teaching skills are really learned in the training process is the most worthy of discussion. You have experience in teaching technology and have enough ability to teach there.
