Thanks Expat Mama, I will look into the Singapore math. I suppose I was after an assessment tool more than a teaching tool. I just feel like he is not learning anything, and I wanted some data points to work with.

I know what you mean about the schools. but I guess I understand from their perspective a bit. There is ideal education, and then there is what is achievable on the ground, and some schools seem to manage better than others.

We might consider a change of school for next year.
