Aside from the fact that most of these certificates are worthless anyway, anyone teaching
in English is an English teacher, like it or not!
Although not compulsory, all teachers here in South Australia are encouraged to complete a certificate in teaching ESL students in mainstream classes, be it Maths, Science, History............
