Co-Teaching

In my district Special Education students are in the regular education classroom as much as possible. I have had the inclusion class room for six of the seven years I have been teaching. This year is the first year that I have had a full day co-teacher. My co-teacher is certified in special education and she handles all of the accommodations for our special education students. Over the six years I have had special ed students I have learned so much about the special education world. I have had one course in special education. I feel that one course is not sufficient. I think that teachers who have the inclusion classroom need to have more instruction in the area of special education. In my opinion, the best way to do this is through professional learning in my district. As I say all the time I'm just a teacher so what do I know. The big question in my mind is Why in the world have the administrators in my district not thought of this yet? Being the inclusion teacher I am with special education students all day long. Doesn't it just make sense for me to have extra training in this area? Please tell me if I am in left field here. This year I have 3 autistic students, a student who was diagnosed developmentally delayed (I suspect she is actually MOID) and a student with a specific learning disability in reading. How do I know and understand each of their diagnoses and how to properly accommodate them? I have taken it upon myself to learn. I ask lots of questions and do research on my own time. I imagine that not all inclusion teachers do this so how do they serve these students effectively? I'm sure that the answer is that they don't. It is time for school districts to wake up and provide, even require this training of its co-teachers. Comments/Questions? Please let me know :)
