It gently explores your child's early development, communication, social relating and any repetitive behaviours or special interests. It is not a test *for* your child to sit — it draws on your everyday knowledge of them, and it is used as one part of a fuller assessment, never on its own.\n\n## What the ADI-R actually involves\n- **It's a conversation with you.** A trained interviewer asks open questions about your child's history and current behaviour — how they communicate, play, relate to others and respond to changes in routine.\n- **It covers key developmental areas.** Questions group around social interaction, language and communication, and repetitive or restricted behaviours and interests, including a look back at the early years.\n- **It is standardised.** Every family is asked in a consistent, research-validated way, so the picture that emerges is reliable and comparable.\n- **It pairs with direct observation.** Clinicians usually combine the ADI-R (your account) with a play-and-interaction observation of the child, plus developmental and medical history, to form a rounded understanding.\n- **It takes time — and that's a good thing.** A thorough interview honours the detail of your child's story rather than rushing to a label.\n\nThink of it as the clinician borrowing your years of close observation, and organising it into something clear and useful.\n\n## When it's used\nThe ADI-R supports the assessment of children where autism is being considered, alongside other tools. It is administered by clinicians with specific training. A diagnosis is never made from any single interview or questionnaire — it comes from a qualified clinician weighing the whole picture together.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment.
