Creative Secondary School in Surrey

Hi, my son is in Year 5 and we are awaiting his EHCP result. He is really good at art and design and very creative. He has an Autism diagnosis with PDA and suspected ADHD and is a bright kid. I wondered if anyone has personal experience (for their child) of a (non-fee paying) specialist secondary which is good for creative kids? We’re near Godalming/Guildford. Many thanks Relaxed
