About Autism in Children

Autism (Autism Spectrum Disorder, ASD) is a neurodevelopmental condition that affects communication, behaviour, sensory processing and how a child experiences the world.

Autistic children may communicate, learn or interact differently, and many also have real strengths, such as attention to detail, memory, creativity, honesty and strong interests.

A high-quality assessment can help families better understand their child’s needs, access the right support, and feel confident about the future.

Signs your child may have autism

Parents often contact us after noticing patterns such as:

Differences in communication (for example, late speech, limited gestures, unusual language, or difficulty with conversation)

Challenges with social interaction or making friends

Sensory sensitivities (noise, textures, clothing, food preferences)

Repetitive movements, routines or strong need for predictability

Very focused interests

Play differences (for example, lining toys up or preferring adults to children)

Emotional regulation challenges or frequent meltdowns

Difficulty with transitions or unexpected changes

School concerns relating to behaviour, attention, routines or social skills

How our autism assessment works

We use a staged approach, which means you can start with an initial assessment first. A full autism diagnostic stage is only recommended if needed.

This staged pathway helps make sure families receive the right assessment and avoids unnecessary appointments.

Stage One: Initial Neurodevelopmental Assessment (required)

Stage One provides a baseline understanding of your child’s development, strengths and challenges. It helps us decide whether a full autism assessment is recommended. Stage One typically includes:

A detailed parent/carer interview

Captures information from the people who know your child best.

Child observation (and brief interview where appropriate)

To see how your child presents in a calm setting.

Review of any relevant medical and school information

Review of any relevant medical and school information

Initial recommendations and agreed next steps

We aim to send a detailed written report with our recommendations within two weeks.

Stage Two: Autism diagnostic assessment, feedback and report (if recommended)

If a full autism assessment is recommended, Stage Two involves a structured evaluation using internationally recognised diagnostic standards and validated assessment tools. Stage Two may include:

Autism-specific questionnaires and interview

Helps explore social communication, behaviour and everyday needs.

School liaison/teacher feedback (with your consent)

Adds valuable insight from the classroom setting.

ADOS (Autism Diagnostic Observation Schedule)

A structured play and conversation-based assessment used to better understand communication and behaviour (completed by a second clinician)

A full autism diagnostic report and a feedback appointment

Clear findings and diagnosis with tailored recommendations. Recommendations may include parent training, additional assessments, or psychological support.

A few things to note

– Payment must be made upfront before each stage to confirm the appointment.

– Some parts of the assessment can be completed online. However, we usually recommend the initial parent appointment and child observation take place in the clinic where possible.

– Before booking Stage One, we may ask you to complete a short form or schedule a brief call so our clinicians can ensure this service is the right fit for your requirements. 

– Assessments typically take place on Thursdays or Fridays. If we are fully booked, we may offer a waiting list.

– In some cases, after the initial assessment we may recommend an ADHD assessment instead of, or alongside, an autism assessment, depending on your child’s presentation and needs. Find out more here.
