My British son (8-years-old) switched from an International School to a Thai Bi-lingual/English Program school a year ago.
The school keeps sending me details of various external Tests such as Thailand English Skills Evaluation Test (TESET), the National Academic Test (NAT), Asian Science and Mathematics Olympiad (ASMO) and English Language competition, Japan International Science and Math Olympiad (JISMO). They all require an entry fee, which is fine, but I have no idea how essential external tests like these are. Do they have any bearing on the student's progress through the Thai system to Secondary level? Or are they just a money-making exercise for Thai parents who like to show off their kids?
