In the US you can only miss a certain amount of days during school year. If over the number the student is held 

back. Do Thailand schools have similar practice? I’m trying to get my in-laws to understand missing school for 

no reason is not good. The nephew is just in first grade and misses 1 to 2 days a week sometimes 3.

 

Majority of Time he doesn’t go to school he stays up to late playing games on phone. Personally I think a phone at that age is not necessary and if so time for use should be set. His Aunt and sometimes Grandparents take care of

him. The parents live in Bangkok.

Every school is different. I'd suspect you'd have to miss a great deal of school not to matriculate to the next grade.

 

I've worked at schools that disallow a student to sit for exams if X% of days are missed. Catch 22.

 

In the schools I've worked at that number is/was 7, 10 and 20% - usually 10% per term.

 

There is usually something going on behind the scenes to allow the student forgiveness as well ;-)

 

Holding students back is not productive. It accomplishes nothing.

Very possibly addicted to video games - everyone else is.
