How Do I Know If My Child Needs an ASD Assessment?

Many parents start wondering about an autism assessment when they notice their child experiences the world a little differently.

This may include differences in social communication, play, flexibility, sensory preferences, friendships, emotional regulation or everyday routines. Some children may avoid eye contact, prefer playing alone, become very focused on certain interests, or feel overwhelmed by noise, clothing, food textures or changes in plans. Other children may be very social but still find conversations, friendships or understanding social rules difficult.

Autism can look different from child to child. It can also look different in girls, who may be more likely to mask or copy social behaviours, which can sometimes delay diagnosis. Research has found that autistic girls are often diagnosed later than boys, partly because their early signs may be less obvious or may be misunderstood.

An ASD assessment helps build a clearer picture of your child’s strengths, differences and support needs. It usually includes parent information, developmental history, questionnaires, direct assessment and clinical observation. Tools such as the ADOS-2 and ADI-R are commonly used in autism assessments, although research also notes that no single tool should be relied on by itself. A good assessment considers the whole child, not just a score.

Seeking an assessment does not mean something is “wrong” with your child. It can help families better understand how their child communicates, learns, plays and copes with the world around them.

A good time to consider an assessment is when your child’s differences are affecting daily life, learning, friendships, behaviour, confidence or family routines.
