This often depends on the size and funding of the school and the type of disability you are referring to. If it is a physical disability then yes schools should be prepared for this. Schools are required to have ramps and other assistance for physically disabled students. As for emotionally or mentally challenged students, some schools do and some don't and parents will have to ask these questions to the individual schools when they are making a school decision. Some private schools are so small that they don't receive enough funding to employ special education teachers and private schools do not receive government funding. Students in private schools are often able to receive some services from the public school board like special education plans, hearing impaired services, blind services, etc. that can supplement what the private school does but this would have to be discussed with the school.
