This article about a court case involved private school parents who want the state to provide in-school special ed services appears in today's Times. The case was brought by 3 families whose children attend religious schools and have to go off-campus for state provided services.
Federal law requires services be given to any student at any school they choose but state law apparently narrows that down and the narrowing seems to be the heart of the issue.
I have mixed feelings on this one. I have a special needs child so I know that desire to get services for your child. But I also feel like the funding is so not there for kids already in public schools that if every child at every single private school had to have services at their school, we could bust the bank.
It's interesting because the heart of public education is that public schools have to take all comers and provide services for them. But for all the perceived greatness of going to private school, the downside is that private schools can choose to not provide services if they don't want to (and expect the parents to get the services from public entities) and private schools get to pick and choose who will attend their schools. There's a downside to every kind of education.
