It's almost certainly divided by socioeconomic status.
I know a few folks whose children went through this. They figured out that they should get their children together in super tiny groups (less than 6 but generally no more than 4) with a single teacher. They tried schooling at home but the "mode switch" was too difficult for their young children to understand.
Guess what? Those children are now so far ahead of their peers it is ridiculous.
Education is almost always dependent upon resource.
