I hope that I have excited you about teaching in Asia. Now let me help you find a job!
If you are British trained or would like to work in a British school, the Times Educational Supplement is free and has many international jobs. Once you open the site, press on the International tab and you can choose your country or specific job. By the way, even if you are not British trained, once you are retained by one of these schools, they will send you to courses to get certification on Cambridge or IB or other programs they run. The trick is to get in but if you have a good resume it should not be a problem
If you are not a certified teacher but still want to get into this game and like the idea of Thailand and occasionally some other countries go to ajarn.com Ajarn means teacher in Thai and they advertise basically for English teaching jobs. Sometimes you can talk your way into a job with a language school and then get training in additional language teaching or you can take a brief course before you apply.
