The assessment tools used for identifying Autistic Spectrum Conditions are the ADOS-2 (used with the individual) and ADI-R (used with parents/carers). These are considered the ‘Gold Standard’ tools for a diagnosis of Autism. 

Other autism-specific tools will be used for pre-screening questionnaires and for gathering information from other settings: school, work, family life.

ADOS-2 Autism Diagnostic Observation Schedule 2nd Version

The ADOS-2 assessment is a behavioural assessment which involves (and is structured around) social interaction between the assessor and the individual. It consists of a series of table top tasks that take between 30 and 60 minutes. There are no invasive procedures involved.

ADI-R Autism Diagnostic Interview Revised

The ADI-R is a structured interview conducted with someone who has known the individual closely since early childhood. In the case of a child being assessed, this will be the parent or caregiver. For adults being assessed this will preferably be a parent /caregiver, but it may be possible to carry this out with an older sibling or other relative. The ADI-R takes between 2 and 3 hours to complete. The interview covers the referred individual’s full developmental history.
