Anyone who can speak English can teach here. It’s harder to find jobs at the international schools if you truly have no experience but, even there, when it gets down to the crunch and someone renegs on their contract at the last minute, people get hired who have questionable experience. As you move down the feeding chain of Shanghai schools, the problem gets worse. At one of the international kindergartens, my daughter’s class cycled through three English teachers over the course of the year and I don’t think any of them had ever had an Early Childhood Ed class. The only saving grace was that the Chinese teacher was trained and good.
My sense is that the American and European schools are more sensitive to criticism from parents and will correct a bad hiring as quickly as they can. I think Asian culture is such that it’s harder to deal with bad hirings in the Asian and local schools.
