Rant alert- Yeah, the same moronic mainstreaming happened here in Alberta. The stress of trying to teach under these conditions led to some of our best retiring at the first (almost) affordable moment or going into private schools. A result is the rapid growth of private schooling, used by those who can afford it.
Of course with the separate system here, catholic students are separated from the protestant, non-religious and other category, and the Muslims and Hebrews also are becoming largely independent of the two main streams.

A daughter of mine is starting a private school in the small B. C. center in which she lives. Fernie already has one, and parents in several other towns are thinking about them.
