When we are talking about training, parents are not given training on how to model good AAC use for children. It tends to be autistic adults or other parents volunteering their time to try to help other parents learn how to model. AAC users are more likely to be able to use it at a quicker rate when it is modelled correctly. There is often the misconception that it will prevent people from learning to talk. Studies have shown that is incorrect; it can actually help to promote users speaking. Even if somebody never speaks, it does not mean they should not be prevented from communicating.
