TESOL Certificate is a certificate obtained after participating in TESOL course training and successfully passing the examination. It is an internationally recognized International English teacher qualification certificate and an authoritative international certificate of professional qualification in the English teaching industry. Those who hold TESOL Certificate are equivalent to having the qualification to teach English as a second language in countries all over the world, and can be engaged in teaching English as a second language all over the world. Therefore, most domestic education and training institutions regard whether they have TESOL Certificate as an important indicator for hiring foreign teachers. Local education departments, official media and more and more parents also regard whether the foreign teachers hired by the education and training institutions hold TESOL Certificate as the main yardstick to measure the level of foreign teachers.

To obtain the authoritative TESOL Certificate, you must study TESOL courses and complete the final examination. The TESOL course is very difficult, the certificate passing rate issued by authoritative institutions is not high, and the industry standard of TESOL Certificate has no unified international norms so far. At present, there are many TESOL education and training institutions with formal qualifications in Britain, the United States, Canada, Australia, Singapore and other countries. The certificates issued by these institutions have their own characteristics in style and are not subordinate to each other. However, the TESOL certificates issued by these institutions also mean that users need to distinguish the authenticity of TESOL certificates. They need to pay attention to whether the certificate issuing institutions have the qualification to issue certificates and whether the certificates issued by them are authoritative.
