If you have no teaching experience, international schools will be extremely tough. You will / should need a TEFL, your degree cert and transcripts and some experience of working with children.
Money wise will vary a lot, but it's not usually well paid - completely manageable don't get me wrong and some schools do pay well, but usually to actual trained, experience and qualified teachers. I taught pre-K through to high school, in an international school, did extra tutoring, planned the majority of the curriculum for English, so good work is out there for qualified people 🙏🏽
Hiya, I've lived, travelled, holidayed and worked in Thailand over the past 17 years (not consecutively), I taught in international schools and pre-K too. I'm a woman by the way too. Happy to chat if you'd like to! It's a daunting but exciting prospect but good to know the pros and cons 👍🏽🙏🏽
