Our Autism Assessment Process
Our multidisciplinary autism assessments are comprehensive and tailored to each individual.
We use a range of tools to ensure high-quality, evidence-based assessment, including gold-standard instruments such as the Autism Diagnostic Interview–Revised (ADI-R) and the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2).
To build a full understanding of your child or young person’s profile, we may also use additional measures such as ADHD screeners, mental health and wellbeing questionnaires, and tools that explore masking (for example, the Camouflaging Autistic Traits Questionnaire, CAT-Q).
Where appropriate, we can offer preschool or school observations, as well as educational assessments with Dr. Rachel Gately, Chartered Educational Psychologist, for an additional fee.
Our work is grounded in a neuro-affirming approach. We use identity-first language (e.g., “autistic person”) in line with the preferences of many in the autistic community, and we focus on understanding each child’s strengths, differences, and support needs.
We are committed to a child- and family-centred approach, ensuring you feel informed, supported, and respected throughout the process.
What does a multidisciplinary autism assessment involve?
Step 1: Initial Contact
After you fill out our Contact Form, our Practice Manager will get in touch to gather some additional information. This helps us understand better your child's needs, and determine whether an autism assessment is appropriate for your child or young person.
Step 2: Assessment Paperwork
After an initial call with our Practice Manager, you'll be invited to complete some online forms. If your child attends a preschool or school, we will also request their input.
Depending on your child’s age and developmental stage, we may also ask that your child complete some short questionnaires to share their own perspective.
Step 3: ADI-R and ADOS-2 Appointments
You'll be offered two key appointments - the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule–Second Edition (ADOS-2). Please note that these tools are always used through an affirming lens.
The ADI-R is a structured interview carried out with parents/carergivers. It's designed to gather an in-depth developmental history and includes a strong focus on behaviours typically observed around the ages of 4–5.
-
Format: Usually conducted online or by phone
-
Duration: Approximately 120- 150 minutes
-
Purpose: To provide detailed background information on your child’s early development, communication, behaviour, and social interactions
You will receive preparation guidelines in advance to help you get the most from this appointment. Many families find this interview helpful, even if it does not lead to an autism confirmation, as it often provides a clearer picture of their child’s developmental profile and support needs.
The ADOS-2 is a structured, play- and activity-based assessment that involves direct interaction between a trained clinician and your child. It is widely regarded as the gold-standard tool for autism assessment.
-
Format: Usually conducted in person (can be offered online for teenagers)
-
Duration: Approximately 40- 60 minutes (age-dependent)
-
Activities: Includes interactive tasks using toys, games, or conversation, depending on your child’s age
If your child is younger, you may be asked to remain in the room during the session. Your role will be mainly observational, though the clinician may invite you to join in at certain points. For older children and young people, the assessment is typically carried out one-on-one with the clinician.
All ADOS-2 sessions are video recorded. These recordings are reviewed by a second clinician as part of our multidisciplinary (MDT) assessment process to ensure thorough, collaborative evaluation.
Step 4: Multidisciplinary Team (MDT) Review
The team meets to carefully review all of the information gathered during the assessment process. A well as results from the ADI-R and ADOS-2 appointments, this includes; input from parents/caregivers, the child/young person, and any educational staff. It also includes a review of any previous professional or school reports.
The team works together to determine whether the available evidence is sufficient to complete the assessment or if further assessment is needed. This might include; a preschool/school observation, or a cognitive/developmental assessment
If additional assessment is required, we'll contact you to discuss next steps and answer any questions.
Step 5: Feedback Session
If no further assessment is needed, you'll be invited to a dedicated feedback session with the Lead Clinician from the assessment. During this session, the clinician will clearly explain the outcome of the assessment and answer any of your questions.
You'll receive detailed recommendations tailored to your child or young person’s unique needs. These may relate to support at home, in school, or in accessing additional services.
This feedback session is designed to ensure that you leave with a clear understanding of the findings and next steps, and that you feel supported in moving forward.
Step 6: Assessment Report
You'll receive a full assessment report within 8-12 weeks from your first appointment date. We understand how important this information is - using a compassionate and supportive approach, our goal is to ensure that every family receives a clear plan of action and the support they need to help their child thrive. The report will include:
-
Comprehensive Summary:
A detailed summary of the assessment process and findings from the ADI-R, ADOS-2, and all other evidence gathered. -
Personalised Recommendations:
Regardless of the outcome, the report will include specific recommendations tailored to your child or young person’s unique needs. These recommendations may cover areas such as:-
Home and school support strategies
-
Access to services or therapies
-
Next steps in your child’s developmental journey
-
-
Next Steps:
Clear guidance on how to move forward with supports for your child. We aim to empower you with the knowledge to advocate for the best possible outcomes.
