Looking for a vocational school in West Sussex orboarding school

[23to14]

My 14 yr old DD with learning difficulties is at a specialist dyslexic school. However she's not coping with the subjects and social aspects. Can anyone recommend a school in West Sussex/Surrey that does Btecs instead of GCSEs?

They’re 6th form courses, as far as I can tell.

There are level 2 (GCSE level) BTECs although I am afraid I only know state schools which do a few alongside GCSEs not a full sweep (nor even if that's possible - English and Maths aren't BTECs I don't think).
