A few points on this: The special education classes for children from Yiddish speaking homes (so called “bi-Y” classes) are not just for children with autism spectrum disorders.
I have taught at a private secular special education school in NYC. The children there had parents who successfully fought for their children to be outplaced because the public schools did an inadequate job of teaching them. For example, one boy was a head taller than his classmates. I was told that he hadn’t learned to read, so the public schools held him back — twice. They used the same failed technique to teach him to read each time, so of course he still couldn’t read. Contrary to what some posters have implied, it’s not just wealthy parents who fight for their kids. That school had children from many socio-economic groups.
Lastly, I don’t want to mention names, but some of the replies here are so full of misspellings and typos that they’re painful to read. Proofreading isn’t that difficult. If you’re a poor spelling, consider typing your reply in a word processor that has spell checking and then doing a copy and paste.
