Step 1: Call your son's Pdoc and have him compose a letter stating that the classroom setting is limiting your son's ability to successfully utilize his education. Have him suggest the online courses; even if they are offered at the school.

Regardless of whether or not they offer the same classes in person - if he is unable to participate in them at his grade level ability then alternative placement and accomodations are legally required to be made. To put it bluntly, it doesn't make a dang bit of difference if they do not normally allow a child to take an online class that is offered at the school because every child is entitled, as dictated by federal law, to a free and appropriate education. A classroom that he cannot succeed in is not appropriate, and you having to pay for alternative placements is not free. Therefore - the school, reguardless of their "normal" protocol, would have to allow an alternate placement.

Step 2: Type up a letter requesting a meeting, and put it in the letter that you have requested this meeting several times in person, and site the date (or approximate date) as well as the person's name you were speaking with. Put in the letter a summary of what you would like discussed, and request that any documentation that will need to be signed be immediatly forwarded to you so as not to delay things once the meeting is scheduled. (This gives you a chance to contact your advocate and have them explain any paperwork the school will send you)

Step 3: Contact:

You are actually quite lucky to be living there! Your state dedicates quite a bit of funding towards non profit org.'s for people with mental disabilities. Call the above numbers tomorrow and explain your situation. I spoke with Michigan Protection & Advocacy Services today (number above) and he was chomping at the bit to talk to you!

Hope this helps a bit. Let me know if you need anything.
