I have an adult, autistic student who I have tutored weekly in programming since about November. His parents would like this tutoring to result in him being able to work as an entry-level programmer, but I have been slowly coming to the conclusion that this may never be viable.
We have reached summer break in the schools, and I would like to have a meeting with the parents and discuss options with them. However, I am unsure how to approach such a meeting. They are already more than aware of his challenges, broadly speaking, and I don't relish the opportunity to close yet another door. They seem, to me, desperate to find somewhere that he can become productively employed. They have been unable to turn him into a highly productive worker at their own restaurant.
He is very affable, however, and highly social. He is also pretty good at calculating in his head. (Don't read too much into this. He is not a savant, he is just a little faster than I am.)
I suspect that he would be better suited to a more hands-on task, such as bagging groceries or stocking shelves. Partly, I believe this because it focuses on his interests directly. He has an acute memory for prices and locations of items in stores. He will regularly come in and tell me about an item that has been moved to a store that I've never gone to, or the name of the night manager (who he has never met, but has been named on a sign), a change in the open hours of a local pharmacy, or the price of gas at the different stations in town.
I have worked very hard this year to make progress with the student, but at this point, I do not think they should waste further money on my tutoring services because I do not think he is being well served by these lessons. How can I approach the parents in a way that would be productive and kind, and how can I prevent offense?
