Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition characterized by challenges in social communication, restricted interests, and repetitive behaviors. Accurate and compassionate diagnosis is essential for early intervention and support, and two gold-standard tools are commonly used in clinical assessments: the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2; Lord et al., 2012), and the Autism Diagnostic Interview-Revised (ADI-R; Rutter, Le Couteur, & Lord, 2003).

The ADOS-2 is a structured, play-based assessment that allows clinicians to observe behaviours relevant to autism across age and developmental levels, while the ADI-R is a comprehensive, semi-structured interview conducted with caregivers to gather a detailed developmental history and symptom profile.

Research consistently supports the reliability and validity of these tools, with studies showing that using both in combination enhances diagnostic accuracy (Gotham et al., 2007; Zander, Sturm, & Bölte, 2015).

Additional assessments will be combined depending on the needs of the individual and their specific presentation. These assessments are available to toddlers, children, youth, and adults.
