What's your school

[Untaught88]

Hi,

Some schools teach up to 5th grade, some to 8th grade and some to 10th. How can I say it when I'm asking someone?

What's your school last grade?
What's your school up to?

I just can't make a sentence. Please help.

"What's the highest grade at your school?"

This could be ambiguous as schools both group students into grades and issue grades to students, but I think it would be understood.
