Summary

  • Autism is a difference in how your child's brain works, not an illness to fix.
  • A psychologist can assess your child, usually as part of a team.
  • Early, strengths-based support helps your child grow up confident in who they are.

If you have started wondering whether your child is autistic, you are probably feeling a mix of questions and worry. Here is a reassuring place to start. Autism is not a disease, and it is not the result of anything you did. It is a different way of experiencing the world. Understanding it early simply means you can support your child to thrive as themselves.

Early signs parents notice

Autism looks different in every child, and signs vary with age. Some parents notice differences in speech, eye contact or back-and-forth play. Others see a strong need for routine, intense interests, or sensitivity to noise, textures or light. None of these alone means a child is autistic. An assessment gives you the full picture.

How assessment works for children

Assessing a child for autism is usually a team effort. A psychologist may work with a paediatrician, a speech pathologist and others, drawing on your observations and how your child engages across settings. The aim is not a label for its own sake. It is an accurate understanding of your child's strengths and needs.

Support that fits your child

Good support is strengths-based. It builds on how your child is wired rather than trying to make them someone else. A psychologist helps with sensory needs, big feelings and self-understanding, and helps the whole family connect. See our guide to autism assessment and support for more.

At what age can autism be assessed?

It can often be identified in early childhood, and assessment is tailored to your child's age. If you have concerns, raise them early.

Will a diagnosis label my child?

Can assessment happen by telehealth?

Parts of assessment and family support can be done by video. Your clinician will advise what suits your child.
