That's interesting. How did they get into that? Do you know the details? Do they skype?
Unfortunately I haven’t talked to them in many years so I don’t have details on how they do it exactly. But I do know that they learned the language they’d be working with in a very short time.
I think the program type may be similar to Skillshare. Skillshare is for those interested in online classes. It is very affordable to join and watch videos to improve skills or learn new ones. Perhaps even adding your own videos of a skill you’ve mastered is really easy but I have not looked into how thats done.
There are also ways to get certified to teach ESL rather easily, though it may cost a little bit upfront to go that route.
