Hi Arts mom,
I am a vision teacher and also has a daughter with albinism who is in college now (3.50 GPA without any help from the disabled students office), and she did not have a vision teacher, just accommodations. There is a shortage of vision teachers, mostly because it is a difficult job and the pay is not equal to the level of expertise needed, its much easier to be a classroom or subject teacher, so the shortage persists and they may never find a vision teacher for your son, so you need to be ready to get Art what he needs to succeed. I would say to focus on getting Art the accommodations he needs, he is entitled to them under section 504 of the IDEA. You and Art can figure out what accommodations are appropriate and call for a meeting with special ed to have them implemented.
First, are you sure he needs large print or a CCTV (I assume this is what you meant by a large monitor)? Not all visually impaired students benefit from large print, the books are large and heavy, the print takes longer to scan across thus slowing reading time, kids hate to be seen with them and they don't fit in backpacks. CCTV's are not readily portable and are difficult to use in middle and high school when students are constantly switching classes. Can he read regular size print? Have you tried glasses with high magnification? My daughter has used magnification glasses since third grade and can read newsprint with them. They are +14.00 and are pricey, especially with the featherweight lenses from Lens Crafters, but they are invaluable.
Can Art see the blackboard well enough to take notes, if not ask for an accommodation that states "print copy of all overheads and notes on blackboard". Does he have trouble with maps? Ask for "all maps enlarged". Get a copy of a scan-tron (the answer sheet they use for state tests where you fill in the bubbles for the correct answer) and see if Art can use it correctly. Sit with him and say #1 is D, #2 is A etc and see if he can use it accurately, if not ask for a testing modification of "no scan-trons, all answers written directly in testing booklet". Look at the PE curriculum and ask Art if he has difficulty with any of the activities, areas to look at are small ball sports and running speed requirements.
The WISC is an IQ test and it is generally given one-to-one. He does not need to take this and you can refuse to let him take it. It cannot be enlarged or the results will not be considered accurate compared to the norms. If you want him to take it, the verbal part only is used for visually impaired students, not the performance part, and the results will not be "full scale".
Hope this isn't too much info and that something I said will be of help to you.
