Dear Marie Demetrius,
When you do such surveys it is important to get different aspects, and sources. As a parent to a boy diagnosed with autism, we see a huge difference between what teachers say and do. Inclusion and integration happens in all schools, however the support and attitude from individual teachers vary immencely. There is a huge difference between what kind of kids are included. In ex. the ABA methodology even kids that deviate a lot are integrated to some extent, whereas in other school settings it is only the kids that are close to the norm that have the benefit of a normal environment.
We have had to take legal action in order to get the inclusion program to continue; this in spite that it has been very succesful. Unfortunately many teachers are humbled by the challenges and are not given neither the support or the tools to handle inclusion well.
There are many complications relating to integration, and am sad to say that you also need to survey parents to understand the extend of the problems with integration. Teachers will only give you the tip of the iceberg.
