Exclusion criteria

A request for service will not be accepted if there is not clear evidence that the child or young person has signs or symptoms that are expected for ASD or when a Paediatrician or Psychiatrist does not support the request.

Diagnostic Assessment

The diagnostic assessment will be performed. This contains:

  • Detailed Paediatric and or Psychiatric assessment (including physical and medical investigations)
  • Developmental, Diagnostic and Dimensional Interview (3di) .A detailed structured interview with parents focusing on the CYP current presentation and developmental history .
  • Autism Diagnostic Observation Schedule (ADOS) usually done by two clinicians working with the child in a series of guided play, storytelling activities. The actual activities vary according to the age of the child.

Further Assessments

The following assessments may be used if more information is required and will depend on individual needs of the child/young person:

  • Individual speech and language profile/assessment
  • Individual cognitive assessment
  • Educational Psychology assessment
  • Observation of CYP across different settings, including school, home and clinic settings
  • More detailed developmental/ social history.
  • Review of information across health, education and social care
  • Consideration of sensory processing needs

Formulation of the diagnosis is done at a multi-disciplinary team meeting where all aspects of the assessment process are considered before an outcome is agreed.  The outcome is then discussed with the family and also with the child/young person where appropriate.  It is usual that a school meeting is arranged to discuss the outcome of the assessment and recommendations for support.  The assessment aims to comply with NICE Guidance.
