I'm not sure whether your country you have this system or not. I did it when I was a college student . So I had a certificate to teach math and chemistry at high school, on the other hand I don't have one to teach English at school . I took some official English grade exams and got enough score to run this branch school.
Practice teaching, reminds me of my young period , with bitter smile
On the other hand my junior high school was a model school for education in Japan

Untill seven years ago, teaching certificates user to be permanent, but now ithey aren't. So probably my certificate has already expired. One of my friend, when she got 50, decided to become a teacher because she has a certificate to teach music st highs school.and she was hired as a part time teacher, and now she works as a regular teacher at high school. She is as old as me. Once I thought I would work as a math teacher at high school, but , as you know I keepthis English school,
