Our child autism assessments are available online across the UK or in person at our Kent and Cheltenham clinics, adhering to NHS and NICE guidelines. Our assessors are experienced in recognising how autism presents across different ages and developmental stages, ensuring assessments are sensitive, thorough, and supportive. Combining specialist knowledge, evidence-based tools, and a compassionate approach, we provide clear, comprehensive assessments that help families understand and support their child’s unique needs.

Autism presents differently in every individual. While many autistic children share common traits, these experiences vary widely and are often shaped by environment, gender, and life stage. Recognising these patterns can help people better understand themselves and access the right support.

What Happens in a Child Autism Assessment?

1

Before Your Child’s Diagnostic Interview

To ensure we’re the right service for your child, we’ll begin with a brief triage process. You (parent/guardian), your child’s school and your child (where appropriate) will be asked to complete a series of questionnaires about them. This will help us to build a comprehensive understanding of experiences and behaviours.
2

Your Child’s Diagnostic Interviews

Your child’s assessment is completed across two online appointments.The first is an ADOS assessment with your child (up to 60 minutes), a gold-standard tool used to evaluate social communication, interaction, and behavioural patterns associated with autism.The second is a detailed parent/carer interview (up to 3 hours), exploring your child’s developmental history, communication, social interactions, and behaviours.
3

Your Child’s Outcome & Report

Following the assessments, our multidisciplinary team carefully reviews the findings against recognised diagnostic criteria. A feedback appointment will then be held to discuss the outcome and answer any questions. Your child’s comprehensive clinical report will be provided within 10 working days and, with your consent, shared with your GP.

Child Autism Assessment FAQs

Who are child autism assessments for?
Our assessments are suitable for children aged six and above who may show signs of autism, such as differences in communication, social interaction, or behaviour. Assessments are designed to provide clarity for families seeking understanding and support.
Are appointments available online or in person?
Private assessments can take place online or in person at our Kent and Cheltenham clinics, depending on what works best for your family.
What happens during a child autism assessment?
Assessments are carried out by experienced Neurodevelopmental Assessors using gold-standard tools, including structured observations and interviews with parents or caregivers. The process is child-centred, ensuring each child feels comfortable, supported, and understood.
How do you adapt assessments for girls and children who mask their traits?
Our experts receive ongoing training to recognise the full spectrum of autism presentations. We understand that autistic girls and children who mask may show subtler traits or use coping strategies that differ from traditional diagnostic patterns. RTN’s approach looks beyond surface behaviours to understand each child’s strengths, challenges, and support needs.
How long does the assessment process take?
We don’t commit to exact timeframes, as every family’s journey is unique. However, once a private assessment is booked, your process can begin within 24 hours.
What does it mean that RTN adheres to NICE guidelines?
It means our experts follow the standards recommended by the National Institute for Health and Care Excellence (NICE) for autism diagnosis in children. This ensures your child’s assessment meets nationally recognised standards of quality and care.
What happens after my child’s assessment?
You’ll receive a detailed report with recommendations for next steps, including support strategies at home, in school, or through therapy.
Can I pay for my child’s assessment in installments?
Yes. Flexible payment options are available to help spread the cost.
