I'm a math teacher looking to boost my resume so that I can work for some of the better international schools in the future. I believe I need to become qualified, and also earn a masters degree. I'm having trouble finding a suitable program. First of all, I'd like to know if it's easier to become a qualified teacher in the US, UK, Canada, Australia, etc. (I'm an American). Anyway, the program must be 100% online and hopefully about $15k or less. Does anyone know if there are any programs out there suitable for me? Thanks!
