"Private School Civility Gap" - NYTimes.com

We have a number of parents in Southern Village who have chosen to send their children to private schools instead of to our excellent public schools. I guess they decided that excellent was not good enough for their kids. I wonder how they react to this study and what their experience has been with students at these private schools? Do they - the schools - have a need for anything like this, just published by the Council of Europe?
