My ds suffers from migraines. He misses 20-25 days of school a year because of migraines (well, he may miss 1-2 of those days for other things like strep throat). In elementary school, a child may be retained if he/she misses more than 30 days of school. In high school, he may not get credit for a semester-long class where he misses more than 15 days of school or a year-long AP class where he misses more than 18 days. Any of those rules can be appealed; however, there's no appeal until the credit is denied originally.

I asked to have an accomodation added to ds's IEP that would allow missed days without penalty, and I was told that missed days are not an IEP issue but an attendance issue. The principal said it cannot be included in his IEP. I can find info on the internet that seems to support my side, but it's not from reliable (that I can tell) sources. Is the school right? Can you help me find reliable information to prove them wrong?
