If he doesn't have it written down, that teacher should walk him back to those classes to write them down! Betcha it happens once, and he'll start to do it on his own (I'm guessing that there is an aide or something in the social skills class along with his teacher, no?)
Is it Marc CHOOSING not to write the assignments, or is it part of his disability? Another idea is that class teachers have to provide his assignments written on sticky notes for him to put into his agenda each day...or he can go to all of his classes and just fill in his agenda before school starts each morning.
