Peacetrain, I guess I am old enough to remember
not to second guess all the research you did for your child, however, being a residential grad myself, I'd like to introduce you to about 17 of the 20-odd deaf students in my graduating class. unfortunately I can't because they only have a 4th grade English literacy level (or LESS!!) and are unable to partipicate in forums like these.
however, since you are actively involved in your child's education, I suspect he/she will do very well. unfortunately most parents don't give a damn so there is a pretty good reason why 70-80% of res. school grads just end up on SSD/SSI.
If you haven't been here:

I'd suggest doing so and take the precautions you need. good luck.
And yeah, Vote for DEAN!
