I homeschool two children with autism, we have for the past two years. To be quite honest, it has been much better than the five horrendous years we spent in public school trying to get therapy services and trying to get appropriate curriculum much less teachers trained to teach children with autism.
One poster was right in that your child needs specialized teaching, one which most schools will not be able to provide based on their needs to teach 20 other children. You are going to be able to teach one-on-one, in a style that suits him best.
Another poster mentioned that the child will need natural settings for learning, how much more natural is the real world, rather than in a classroom setting and then trying to generalize to the real world?
We have worked quite hard to provide fair and appropriate education for our children. We consult with a specialist once a month to discuss behavioral and academic developments. At the young age you describe, we had an ABA trainer at our house once a week to help us with our homeprogram. That would help with the stubborn attitude, a good program with rewards will help tremendously.
It would be helpful to sit down and write what he does know, and then what logically comes next. Then you need all the small increments that come in between, and that's where an ABA or psych will come in handy, they often know those tiny steps (and I can tell you that the teachers never knew) It IS easier to just sign your child over to 'professionals', but it doesn't guarantee that it's the right thing to do. Some kids do very well in public school setting, but those kids would thrive just as much in a structured home setting.
Kids with autism often learn to write long after reading, and they usually learn to read with a whole word approach, phonetics does not make sense. My daughter was low-functioning and once she hit about 300 hundred sight words, the phonics just kind of kicked in. I think she was about eight. I would label everything in your house. Go to www.trainland.tripod.com and download the pecs pictures there. USE USE USE those and use the sign language, it will kick start vocalizations.
this is a lot of work, but it is so rewarding, without all the frustrations of IEP's and legalities and fighting for services. i can assure you that in my experience with friends across the country, there are very few schools that provide enough speech, OT and physical therapy to make it worth enrolling your child just for those services. There are even less that provide ABA or other specialized teachings.
Only you can make the choice, but you are welcome to email me anytime. You might also search yahoo groups for homeschooling special needs groups. For homeschooling laws, check out www.hslda.com. It's much easier than you think, many states don't require any kind of notification, much less testing.
