I'm trying to help a 29 year old male find employment in the painting & decorating field

I am a support worker within supported housing and am looking for information to help a 29year old male find employment in the painting & decorating field. He recently failed a test at the Skills Company as he could not complete the questions in the time allowed. He has the practical skills but needs extra time for written work. I know help /aids are available for people with dyslexia so surely there is help somewhere for people with cerebal palsy. I just don't know where to look. Any suggestions will be greatly appreciated.
