Autism guidance for parents
Autism assessment for children
Understand assessment options, prepare useful information and feel clearer about the next steps for your child.
An assessment explores whether your child is autistic, alongside their strengths, experiences and support needs.
Understanding your child
When might an assessment be helpful?
If you are wondering whether your child may be autistic, discuss your concerns with a GP, health visitor or relevant professional.
You may have noticed differences in communication, social interaction, routines, interests or sensory experiences. Explain their effect on daily life and what helps your child feel comfortable.
Recognition at different ages
Some children are assessed in early childhood. Others are identified later, when changing demands make their needs more apparent.
You do not need to wait for every possible sign before seeking advice.
A fuller developmental picture
Assessment considers whether diagnostic criteria are met, alongside other possible explanations and additional needs. A list of signs alone cannot establish a diagnosis.

NHS and private autism assessments
NHS pathways
Ask how referrals work locally. Depending on the service, a GP, school or health visitor may be involved. Check eligibility, the information required and current waiting arrangements.
Ask what support is available while waiting.
Private pathways
Check the provider’s suitability for your child’s age and needs, professional qualifications, assessment approach and full fee.
Ask what the report, feedback and follow-up arrangements include, and whether additional appointments cost extra.
What to expect
What does an autism assessment involve?
The format varies, but the aim is to understand your child over time and across relevant situations.
Developmental history
Conversations about early development, health and everyday experiences, including your child’s strengths and interests.
Meeting your child
Age-appropriate interaction, conversation or activities to explore communication and play, with suitable adjustments.
Information from others
Relevant reports and observations from nursery, school or people who know your child well.
Who is involved?
Assessment may involve professionals such as psychologists, paediatricians and speech and language therapists. Ask how the service brings together the appropriate expertise for your child.
Tools should contribute to the wider clinical assessment. Ask how findings are interpreted and what happens if further information is needed.

What can you prepare?
A few clear examples can be more helpful than trying to remember everything during the appointment.
Information to gather
- Relevant developmental and health information.
- School or nursery feedback and support plans.
- Everyday examples of difficulties and what helps.
- Your child’s strengths, interests and views.
- Questions you want the clinician to answer.
Helping your child prepare
- Ask who they will meet and what may happen.
- Use a simple explanation suited to your child.
- Share communication, sensory or accessibility needs in advance.
- Ask about breaks and familiar items.
- Check whether you can stay with your child.
Understanding the outcome
What happens after assessment?
Ask for an explanation of the findings and how they relate to your child’s everyday experiences.
Feedback and report
Confirm when feedback and a written report will be available. Ask about strengths, identified needs and any uncertainty.
Practical recommendations
Clarify which recommendations apply at home or school and who can help put them into practice.
Further support
Ask about follow-up, other assessments or advice, and support for your child and family.
What if autism is not diagnosed?
Ask why the conclusion was reached and what the findings suggest. Your child’s needs still matter. Discuss appropriate support, further advice or a review where uncertainty remains.
Support alongside assessment
Keep school support moving
Discuss current needs with your child’s teacher or SENCO while assessment is being considered or awaited. Agree practical support, responsibility and a review date.
An assessment report may contribute evidence for an EHC needs assessment or EHCP in England. An autism diagnosis does not automatically lead to a plan. Education systems differ elsewhere in the UK.
Common questions
Before you take the next step
What age can children be assessed?
Some children are assessed in early childhood and others later. Ask the service about its age range and suitability for your child.
How many appointments will there be?
This depends on the service and your child’s needs. Ask about expected appointments, time to feedback and arrangements if more information is needed.
Can school make a referral?
In some local pathways, school may need to refer. Ask your GP or local assessment service how the process works in your area.
Does recognising autism traits guarantee a diagnosis?
No. The clinician considers the full developmental picture and whether diagnostic criteria are met.
How much does private assessment cost?
Fees vary by provider and the assessment required. Request an itemised quote covering appointments, report, feedback and any additional costs.
Does a diagnosis automatically mean an EHCP is needed?
No. In England, EHCP decisions depend on special educational needs and required provision. Continue discussing support based on your child’s needs.
