What should I expect from a 'Sensory Support Team'

[Katymac]

How can they help?

what should I be asking for?

It's for sight problems

My ds wears a hearing aid, and a lady from sensory support came to see me. They go into schools/nurserys and give advice, for e.g they said about where in the class my ds should sit, that they should always face him when speaking to him, that kind of thing. She checked his hearing aid, and changed the tube on it.
