Autism spectrum disorder (ASD) diagnosis

Autism diagnostic observation schedule (ADOS) test

ASD assessment service for children and families

About

Our ASD assessment service provides support for children and their families who are looking for an autism diagnosis. If your child is experiencing difficulties, an assessment may lead to an explanation and help you plan for the most appropriate care, education and support.

Need to know

  • What happens icon plus

    If your consultant suspects autism spectrum disorder (ASD), your child will be referred for a semi-structured assessment of communication, social interaction, and play (or imaginative use of materials) using the autism diagnostic observation schedule (ADOS) test. This test involves your consultant neurodevelopmental paediatrician and our multidisciplinary team which may include psychologists, speech and language therapists and physiotherapists.
  • How to prepare icon plus

    The symptoms of autism spectrum disorder (ASD) can often be seen between one and three years of age. While your child may have a a developmental evaluation before they turn two, a definitive diagnosis may not be made until a later stage. An initial assessment for your child involves a consultation with one of our consultant neurodevelopmental paediatricians. They specialise in the diagnosis and management of children with developmental difficulties and disabilities.
  • Afterwards icon plus

    Following the assessment, you will have an appointment with your consultant neurodevelopmental paediatrician who will provide formal feedback and a plan of care.
