Hello I’m a retired primary teacher and I’ve been thinking about getting into teaching online. Teaching English seems a good idea, but I’m looking for some advice please. Some courses are a few hours long and some are weeks or months long. Would I be best to study for TESOL or TEFL? I’m unlikely to want to teach abroad, it’s going to be online. Should I join agencies? I did aTESOL unit as part of my teacher training ( mid 90s). I’ve also taught children for whom English is not their first language. I would much appreciate some advice! Can anyone point me in the right direction?
