Your child’s autism assessment: what to expect

Our Children’s Autism Assessment is for children aged between 2 – 18 years old. The assessment involves a series of assessments and collaboration between experts. This may include a Paediatrician, a Child Psychiatrist, a Speech and Language Therapist, an Occupational Therapist and a Psychologist.

The assessments include the use of gold-standard diagnostic tools, tailored around a child’s specific constellation of symptoms. Our assessment for autism starts at £1,650.

How to prepare for your child’s autism assessment

Prepare for the assessment by collating any previous medical documentation, assessments, school reports, and records detailing your child’s early developmental milestones. These can be beneficial to the assessment team and will be reviewed as part of a broader evaluation of your child.

It is recommended to bring any documentation along to the assessment. In some instances, our team may request these be sent in advance, especially for virtual appointments.

On assessment day

  • 1

    Part 1: an interview with parents/carers

    The first part of the assessment is a diagnostic interview with the parents/carers, usually in the form of the Autism Diagnostic Interview Revised (ADI-R) or another form of detailed neurodevelopmental history. Parental interviews may be conducted virtually, at your convenience.

    This ADI-R/ neurodevelopmental history assessment takes around 2 hours to complete and comprises a series of questions regarding your child’s development, social interaction, communication and language, and patterns of behaviour.

  • 2

    Part 2: an interview with your child

    The second part of the assessment is the Autism Diagnostic Observation Schedule (ADOS) which is conducted with your child.

    ADOS assesses your child’s social and communication behaviour using age-appropriate games, imaginary play, activities and conversations with the doctor. The assessment takes approximately 45 minutes to complete.

Report, diagnosis & recommendations

Within 2-4 weeks, a detailed report, specifically tailored to the educational, behavioural and developmental needs of your child is provided. This comes with a virtual follow-up appointment to discuss the diagnosis and further recommendations. The diagnosis is based on DSM-5 criteria (The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) and the ASD report and our recommendations are based on NICE Guidelines

Possible recommendations may include:

  • referrals for therapies
  • further testing options
  • Early Start Denver Model (ESDM)
  • parental support groups, courses, advice
  • useful information on autism and references

Diagnosing autism in children & treatment options

As with any developmental condition, it is ideal to get a diagnosis as early as possible. An early and accurate diagnosis is critical for early intervention to improve the management of symptoms in the short and long term.

The earlier the intervention, the greater chance of a successful outcome on the trajectory of a child’s future development. At an early age, our brains are actively developing, and are thus more malleable, enabling a faster acquisition of cognitive, motor and social skills.

There is no ‘cure’ for autism, however, there are a number of treatment options designed to improve symptoms.

What is autism?

Autism, also known as Autism Spectrum Disorder (ASD), is a neurodevelopmental condition that affects communication, social interaction, and behaviour. It is called a spectrum disorder because it affects individuals in different ways and to different degrees.

Autism affects over 1.7% of children in the UK

Latest research (2021) by Cambridge, Newcastle and Maastricht Universities has demonstrated a significant rise in autism amongst children in the UK.

An assessment of 7 million children (aged 2-21 years) found 1 in 57 (1.76%) were on the autism spectrum. Boys showed a higher prevalence of autism (2.8%) than girls (0.65%).

Symptoms of autism

Babies & toddlers

It is sometimes difficult to recognise the early symptoms of autism in babies and toddlers. However, possible signs of autism in babies and toddlers can include:


  • No words by 16 months

  • Lack of meaningful, two-word phrases (not including imitating or repeating) by 24 months
  • Limited back-and-forth gestures, such as pointing, showing, reaching or waving by 12 months

Possible signs of autism in a child can include:
