Inclusive education is an excellent philosophy, if it can be implemented.
The issue is the lack of services and resources to make it work. I've heard of situations where children with intellectual disabilities, for example, end up in regular classes. However, they spend time in the school hallways, or they're made to do photocopies. They don't receive the same quality of education, even though they're in a regular class.
This education is called “inclusive,” but it isn't.
