I was a teacher at a university before.
After finishing the teacher education program, you do not need to take any test unless somebody doubts your English proficiency. Before you attend the teacher education program, you need to take an English test, TOFEL or IELTS for the admission.
"Hi haha4,
I am very interested in being a Intermediate/Senior Mathematics and Science teacher too. Were you a teacher before? After finished the teacher education program, whether did you need to pass a english test cetified by OCT to get the Certificate of Qualification? (like TOFEL, IELTS, MELAB, etc.)
Thx in advance."
