Why Families Choose a Private Assessment
NHS waiting times for autism assessment in Southampton have grown considerably in recent years. Pathways for both children and adults are managed primarily through Southern Health NHS Foundation Trust, which covers Southampton and the wider Hampshire area and faces significant referral pressure. For Southampton families waiting years for a diagnosis, a private assessment provides access to the same clinical standards — ADOS-2 and ADI-R diagnostic tools — typically within four to eight weeks of enquiry.
A private autism assessment in Southampton gives your family access to the same diagnostic frameworks used by the NHS — 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.
