The acceptance of a private diagnosis is dependent on many factors and not just the robustness of the assessment and the experience of the assessor.

I have not had my assessments rejected by any service, that includes both NHS and local authority.

I always suggest that if you are looking for the diagnosis to be accepted by any service, GP, MH services psychology etc, that you discuss my credentials with them and ascertain if they will accept it before you commit to an assessment. For this purpose, I have added below information about my experience.

I was the clinical lead for 20 years with Scotland's largest Adult Autism Team Autism, my private assessments follow the same format as my NHS assessments.

I am an author of SIGN guidelines.

I sat on the national steering group at the Scottish Government where I have led a working group on increasing competencies across health to diagnose autism spectrum disorders.

My assessments are underpinned by the DISCO assessment (Diagnostic Interview for Social and Communication Disorders) and I was the Scottish trainer for DISCO up until 4 years ago when the license ceased after Lorna Wing's death. I have trained 300+ clinical psychologists, psychiatrists, and paediatricians to recognise and diagnose autism.
