The autism diagnostic assessment is a highly specialist assessment. There are no short-cuts. A less robust assessment, either online or with a sole professional, is more likely to result in mis-diagnoses or an incorrect diagnosis.


Whether the outcome is you, or your child, receiving a diagnosis of an autism spectrum disorder or confirmation that you, or your child, do not meet diagnostic criteria for ASD, we aim to help you develop a better understanding for you, or your child.
