A rather late reply but we are now in y8 at Charter ND. Not been a straightforward journey and still trying to best navigate the system in order to best support our son in mainstream. FYI Charter ED is only now about to open the Autism Unit but the experience at Charter ND means that we are unlikely to move him as the disruption would probably out weigh any benefits, or so we have been lead to believe by the support staff we speak to.
