Please mention that you found the job on Teast for the school's reference.


📌 Please review the requirements to teach English in Thailand before you start applying for teaching positions. If the job post specifies "NES" or "Native English Speaker", it typically means applicants are required to be from one of the following countries: United States, Canada, United Kingdom, Ireland, Australia, New Zealand, or South Africa. However, in some cases, this may indicate a preference rather than a strict requirement.


⏳ Due to the high number of applications the schools receive they may not be able to respond to every application. If you don't hear back from them within a week or so, it's best to move on to the next job.


⚠️ Watch out for agencies that charge fees or take a cut of your salary. Good agencies get paid by the schools - not by taking money from you. If you’re not sure how they make money, just ask. If they say they take a percentage, that’s a red flag - avoid them and let us know so we can ban them from the site. Unlike other job boards that allow these kinds of agencies to advertise at your expense, we don’t - we’ve already banned several to stop teachers from being underpaid or exploited.


⚠️ When applying for jobs, you should NEVER have to pay to apply. You should also NEVER have to pay to buy anything which they then pay you back for later. NEVER PAY FOR ANYTHING! Also always verify you're actually talking to the company in the job post and not an imposter. Scams in TEFL are rampant, be careful!
