It took 8 months to teach one student how to perform his job functions at a local chain restaurant - selecting a knife, a large fork, a salad fork and a spoon and then rolling them into a cloth napkin. But at the end of that 8 months, he knew how to do his job with perfection and worked there for almost 10 years instead of spending his days in a group home or a bedroom in his parent's home. His IQ was around 65. Other students were taught to peel and core apples at a bakery, detail cars at an auto dealer, and bag groceries at a grocery store. I taught them how to ride the bus, clock in and out, and manage specific behaviors that were a problem in the work place.
This training does work for low-IQ people. Once they (finally) get the hang of it, they are quite able to do it.
It just takes a lot of time to get them to that point and it is better than a group home or in the parents' home.
