private schools in many countries don’t require a degree. They look at other qualifications. I know someone who has bern teaching for many years and is far more skilled than someone walking out of school with a piece of paper.
Degrees aren’t everything and often don’t actually define one’s skills. After a career in another field, although it also required a great deal of teaching, I taught kids for several years. I don’t have a teaching certificate. I’m not currently looking to teach in Thailand and I haven’t even decided for certain if I will stay. Many countries would allow me to teach without a teaching certificate though. There’s nothing magical about a piece of paper. It’s one assessment of one’s skills, not the only one.
