Why Families Choose a Private Assessment
Waiting times for autism assessment in Cardiff have grown considerably under NHS Wales. Children’s and adult pathways are managed by Cardiff and Vale University Health Board (Cardiff and Vale UHB), which serves a large population across Cardiff and the Vale of Glamorgan. For Cardiff families waiting years for a diagnosis under the NHS Wales pathway, a private assessment offers the same clinical standards — using ADOS-2 and ADI-R diagnostic tools — typically within four to eight weeks.
A private autism assessment in Cardiff gives your family access to the same diagnostic frameworks — including the ADOS-2 and ADI-R tools — conducted by a qualified clinician, typically within four to eight weeks of enquiry.
All providers on The SEND List have their professional registration checked before they appear in the directory. We verify HCPC registration for clinical psychologists and speech and language therapists, and BPS registration where relevant.
