For all of you who are interested in teaching in Thailand, there have been a few changes since the beginning of 2010.
The Teacher's Council of Thailand has decided to enforce the rules that they established a couple of years ago.
FYI, The Teacher's Council approves all requests for Teacher's Licenses before they go to the Ministry of Education for issuance of said License. This is the first step in getting your Work Permit and Visa. If you don't meet their criteria, you won't get a license nor work permit nor visa.
The rules can be found at http://www.pathum2.net/grp4/pvcht(E).pdf
The major change is that you can no longer come to Thailand with just any Bachelor's Degree and expect to teach. They want people here who have BEd or MEd degrees and preferably current Teaching Certificates from their home countries.
If you do not have an education degree, there is still a way to teach. However, it will cost you 60,000 baht to take the courses. You will get a Thai Teaching Certificate that is only good in Thailand.
There is still some confusion about the requirement to have 1 year previous teaching experience in Thailand if you don't have an education degree. I will post more as I find out more.
You can check on http://www.ajarn.com for more information, but be advised: Ajarn.com is an open board and there is a lot of misinformation up there.
If you have any questions, please let me know. I will try to answer them, but as I said, the information available is still confusing. It appears that there will be a shortage of qualified teachers soon as many people don't want to pay the money for the classes to get a piece of paper that is only good in Thailand. We are waiting to see what happens.
