ASD Assessments

Currently unavailable

Autism is a complex neurological disorder that affects individuals in unique and diverse ways. As such, it is important to properly assess and diagnose autism spectrum disorder (ASD) in order to provide appropriate support and intervention. Effective assessments are essential for understanding an individual's strengths, challenges, and needs, which can then guide the development of personalised treatment plans and accommodations.

Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a lifelong developmental disorder that affects how people behave and interact with the world around them. The symptoms of ASD typically appear during early childhood and can affect a person’s social skills, communication, and behaviours. The main characteristics related to ASD fall into two broad areas: difficulty with social interactions and communication and restricted and repetitive behaviours and interests. The common signs and traits of ASD in children include lack of social or emotional exchanges, difficulty developing and maintaining relationships appropriate to their age, delayed expressed speech and understanding of speech, and restricted or fixated interests. In adults, ASD traits may include difficulty with social interactions and communication and restricted and repetitive behaviours and interests.

What does an ASD assessment involve?

An ASD assessment is a comprehensive evaluation that aims to diagnose or identify any potential autism spectrum disorder in an individual. It involves a series of tests, interviews, and observations.The purpose of an ASD assessment is to assess the individual’s strengths and weaknesses, communication skills, social interactions, and behaviour patterns in order to determine if they meet the criteria for an autism spectrum disorder diagnosis. This process can also help determine the severity of the disorder and any co-occurring conditions.

Why are ASD assessments helpful?

ASD assessments are helpful because they can provide a formal diagnosis, which can aid individuals and their families in understanding and accessing appropriate interventions, support services, and educational resources tailored to specific needs. These assessments can also help determine an individual’s learning capability by identifying cognitive strengths and weaknesses and can assist with developing individualised support and learning plans.

How long does an assessment take and what do I need to bring?

An ASD assessment can be  divided into 2 days – one day for the ADOS test, and another one for questionnaires and diagnostic interviews. A typical assessment is as follows:
