Secondary school suggestions for high functioning asd in Somerset

[TheOakWillowTree]

I’ve got a high functioning autistic child/teen who I feel will struggle in most mainstream, but I think in the right learning environment (e.g. smaller class sizes, accepting/supporting) they will thrive and get a normal number of GCSEs.
We're looking for Yr 9. Can anyone recommend any independent schools in Bath or Bristol, or Somerset overall, that should be considered?

If DC is a DD, Royal High can be supportive depending on how DD’s ASD presents and how much support she needs. Some find Taunton nurturing, but, again, it depends on the presentation/level of support needed.
