I have some magic words to share with you: Proven Framework for Mainstreaming.
The words came to me and I knew I had the concept I was trying to articulate when I was feeling dismayed at the other school choices I had.
When discussing behavior issues involving your child with sensory processing disorder make sure to mention that what looks like bad behavior could be due to involuntary reactions to sensory overload.
When talking about classrooms or school, use the word appropriate, as in free appropriate public education (FAPE,) and a certain class room setting that is appropriate for a child with your child's disabilities.
It is helpful to be familiar with the terms already in use to be able to use them for your child's benefit. Here is a handy glossary of the terms used in discussing special education.
Here is a link to Pennsylvania's Department of Education's pamphlet for understanding the language of special education. It has helpful sections on disabilities and behaviors, and educational terms.
Understanding the Language of Special Education: A Glossary for Parents and Educators
It can be tricky when you see or know of something you don't want for your child. You must find a way to frame or express what you DO want for your child. Many schools have policies about not reqesting a specific teacher by name for your child. I always make sure I express in Random Guy's IEP what kind of classroom and teaching style is helpful for him to make progress.
Use the magic words and you may find you get exactly what you want.
