Don't do your post-graduate studies outside of Thailand
In the past, a well-know organization recommended completing postgraduate studies in Thailand or in the Philippines. Teachers completed their post-graduate studies, got their licenses and everything was OK. At the end of 2021 everything changed for those who used the Filipino intermediary. Many teachers received their diplomas along with their CAVs (from Filipino Comission on Higher Education) and applied for licenses.
The response from a well-known organization was shocking: you must take the exam, but if you want to take the exam you should first present an equivalence of educational qualification from the Thai Ministry of Higher Education. Of course it takes several months to get this document and teachers didn't get it on time.
In conclusion, many teachers have neither been licensed nor given the opportunity to write the exam. Has anyone been held accountable for destroying the lives of dozens of teachers? Of course not.
