ASD Behaviour Trait Checker

If you suspect that your child has ASD, or if you have concerns that your child may be Neurodivergent but you are unsure of the condition, here is a simple ASD behaviour trait checker to begin with.

If your child’s age is below three years, kindly refer to this symptom list, or if your child is three years or older, please check this symptom list instead.

Upon completing the checklist and if your child demonstrates a more significant number of symptoms identified by the ASD behavior trait checker, it is advisable to seek an official diagnosis from a medical specialist.
While awaiting an official diagnosis, we offer some suggestions to assist you in better supporting your child.

What is Autistic Syndrome Disorder (ASD)?

ASD is a complex neurodevelopmental disorder that affects behaviour, communication, and social interaction. It can be difficult to identify the signs of ASD in a child since they vary from person to person and can appear differently in different situations. There are several signs that may indicate your child has ASD.

What are the characteristics of ASD?

The National Institutes of Mental Health has created a list of behaviour traits that are often seen in autism. It’s important to bear in mind that none of these behaviours on their own is likely to indicate autism. Autism is a pervasive developmental disorder, which means that a child must display many of these behaviours in order to qualify for a diagnosis.
