Meanwhile Billy, 23, who has cerebral palsy, had to fight two tribunals challenging his local authority to fund his place at National Star.
It is not cheap, with the average cost per student anywhere between £20,000 up to £300,000 a year depending on individual requirements on living, therapy and care.
It is funded in England through Education, Health and Care plans (EHCPs) but his family, say National Star was 100% the right place for Billy.
His mum Jeanette said: "He's a lot more mature since he's been here and his communication has got so much better."
Dad Rich says he's so friendly but his social skills have improved.
"At restaurants he used to spend most of the evening sitting with other people on their table and talking to them but he sits with us now! We've ended up in the kitchen with the chef before now," he added.
A lot of the work the team at National Star are doing now is starting to prepare students like Billy for leaving.
His family hope he'll win funding to live independently in supported accommodation.
Working with his personalised learning coordinator, Ruth, Billy is starting to understand that next July he'll have to leave.
He signs that he's sad, but using a communicator, he says he wants to work as a refuse collector.
