Were there any math questions about interest rates on loans?

No, just True or False on whether you must pay them back.

That is a logical conclusion, however many of us know full well,  LOGIC is not a skill Thais have at any level .!!!!

We are speaking of Thai educators; some of them, at least, have knowledge of such tests. Any of them who went to an English-speaking country for their graduate degrees had to take such tests.

What would the test consist of?

Discipline-specific tests, of course. For example, English comprehension, grammar, and vocabulary for the English teachers.

I assume their ability to answer questions in Tinglish, rather than English, having seen other comments about it.

 

How about their comprehension, grammar, vocabulary and ability to speak and write proper English?

because foreigners don't understand the envelope rule so well and also it would be a major embarrassment.

I imagine a major embarrassment may be the numbers of current NES teachers who could not pass such an exam.

Well, that may be the reason foreign teachers would be reluctant to take the test, but not the Thai educators; they would just administer the tests.
