Alternatives to studying Prathom in a school.

There are great alternatives to studying Mathayom for secondary level students. For example there are international courses and examinations here such as the iGCSE, GED, A levels, O levels, IB.

For example, instead of going to a school, the student can study in places such as aims:

And then sit the internationally certified exams and gain internationally (and locally) recognized qualifications.

For example, students typically sit the iGCSE at around 14-16. The Thai MoE certify this as equivalent to the Thai M6 Cert.

The student would not go to Thai school, and would end up with the same qualifications as their peers in the UK or America.

So there are decent alternatives to Thai secondary (Mathayom) school.

My question is, are there anything similar for primary students?

Even if the courses are done in conjunction with the Thai Prathom curriculum and are not international. For example, are there private learning centers where a primary student can study the Math, Language, Social etc etc courses that they would study in Thai school? And then sit the exams at the same time as everyone else.
