Autism Assessment Service

We provide an autism spectrum disorder assessment service for children.

This service is available to parents who are concerned that their child or young person has an autism spectrum disorder and are seeking advice on whether or not to pursue a diagnostic assessment now or in the future.

The assessment process complies with best practice as specified by the National Institute of Clinical Excellence (‘NICE’); guidance available here.


Very professional service with a friendly attitude towards young children. Thorough and concise reports and feedback after each session. Would highly recommend this service for anyone looking for help and support in this area.

Background information

Assessments are undertaken by a multi-disciplinary team comprising a chartered psychologist and a consultant speech and language therapist. All clinicians involved have extensive experience working with people with social communication difficulties and diagnosing ASD.

Before agreeing to undertake a full assessment, individuals are requested to complete a questionnaire providing information about their concerns, presentation and some background information. The information obtained will be used to decide whether there is sufficient evidence to warrant a full assessment.

Assessment Process

Full assessment, should it be carried out, is likely to entail a combination of the following, depending on the specific needs and presentation of the child:

  • Meeting with parents / carers to take a comprehensive developmental and medical history, based on the Diagnostic Interview for Social and Communication Disorders (‘DISCO’).
  • Child assessment using the Autism Diagnostic Observation Schedule (‘ADOS’) (play-based for younger children).
  • Detailed information from education staff.

In line with NICE guidelines, the assessment is carried out as part of a multidisciplinary team, joint with a psychologist, and detailed information is also gathered from the child’s school.

Additional assessments may be needed depending on the presenting needs and/or in order to guide appropriate support and intervention.

We also partner with professionals from the following organisations to complete child ASD assessments.

Please contact them directly for information on referral and costs.
