As others have said, things can get ifffy quickly. Special needs students, are just that, and as such need lots of understanding supervision. I taught HS for 36 yrs. and almost always would have one or two students with special needs. I was a little bit of an SOB in that when I had this type of student in with my regular classes, I required an aide. This was to handle those times when I would be working with others students far from the special needs student. Every special needs student that came into the ceramics room had individual needs that required a bit of adjustment on my part for them to have a successful experience.I had many times when tools would have to be adapted for handicapped students, or times when other procedures had to be worked out for these students. I nearly always got one other student to help out by helping with joins, wedging clay, etc.
This sort of endeavor can be very enriching and gratifying. However, it is not to be considered a lark, as you will definitely work harder than you thought possible, have more fun than you thought possible, and cry a lot of tears.
Good luck. . .
