What to Expect from a Child Autism Assessment in East Dulwich & Ealing
Navigating the world of autism assessments can feel overwhelming, especially when you’re trying to make the right decision for your child’s future. If you’re a parent in London and you’re exploring whether your child may be autistic, understanding the assessment process is an important first step.
At ASD Child Ltd, we support families through every stage of their neurodevelopmental journey. This guide will walk you through what an autism assessment involves, why early diagnosis matters, and how you can access trusted support with confidence.
The Importance of Early Autism Diagnosis for Children
Early identification of autism is often the key to unlocking the right support at home, in education, and across healthcare services.
Many families in the UK are facing long waiting times through NHS or school-based referral routes. A private autism assessment can offer a faster path to clarity — reducing uncertainty, relieving stress, and enabling timely interventions that match your child’s needs.
Parents typically consider an autism assessment when they notice signs such as:
- Delays in speech or communication
- Avoidance of eye contact or social interaction
- Sensitivity to sensory input
- Repetitive behaviours or narrow interests
- Resistance to change or routine disruption
ASD Child provides clear, NICE-compliant evaluations that help families access the right support as early as possible.

The Autism Assessment Process – Step by Step
Our assessment process is structured and supportive, designed to provide a full picture of your child’s developmental profile.
1. Free Initial Telephone Consultation
Start with a no-pressure conversation. You’ll speak with a specialist to discuss your concerns, ask questions, and find out whether an assessment is appropriate for your child.
2. Parent Interview (ADI-R)
Conducted remotely, this detailed consultation covers developmental history and behaviours. It uses the ADI-R (Autism Diagnostic Interview-Revised), a trusted tool led by a clinical psychologist.
3. Child Observation (ADOS-2)
Your child is seen in-person for a structured, play-based session using the ADOS-2. This session takes place at one of our two clinics — in East Dulwich or Ealing — and helps assess social communication, interaction, and behavioural patterns.
4. Clinical Review & Diagnosis
Our multidisciplinary team reviews all findings against NICE and DSM-5 criteria. If your child meets the threshold for autism, we provide a clear, helpful explanation and next-step guidance.
5. Feedback & Written Report
A detailed diagnostic report is prepared for you, suitable for EHCP applications, school support, or healthcare providers. We also offer a follow-up call to explain everything in plain English and answer any questions.
