Accuracy depends on the tool, the child's age and the setting, so a positive screen always leads to a clinician-led assessment. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.","answer_md":"*Screening tools are clever signposts, not crystal balls — they tell us when to look closer, not what the answer is.*\n\n## In short\nGood autism and developmental screening tools are reasonably accurate at flagging children who *may* benefit from a closer look, but no screen is a diagnosis. The best-known tools catch a large share of children who genuinely need support, while also raising some false alarms — which is exactly why a positive screen leads to a proper assessment, never a label. Think of a screen as a smart first filter: useful, quick and worth doing, but always followed by a clinician's judgement.\n\n## What \"accurate\" really means\nNo screening tool is perfect, and accuracy has two sides parents find useful to understand:\n- **Sensitivity** — how well a tool *catches* children who truly need support. Higher sensitivity means fewer children slip through.\n- **Specificity** — how well it correctly *clears* children who are developing typically, avoiding needless worry.\n\nWidely used tools generally perform well but trade these off: a screen tuned to miss very few children will, in turn, flag some who turn out to be developing typically. That is by design — in young children it is safer to look closely and reassure than to wait. Accuracy also shifts with a child's age, the setting, and whether a parent-report tool is completed thoughtfully. This is why a screen is a starting point, not a verdict.\n\n## When a screen says \"look closer\"\nA \"positive\" or \"at-risk\" screen does **not** mean your child has autism or any condition. It means a structured, clinician-led assessment is the right next step to understand the full picture. Equally, a \"low-risk\" screen is reassuring but not a guarantee — if you still have concerns about how your child communicates, plays, moves or connects, trust your instinct and ask for a developmental review. You know your child best.\n\n## The Pinnacle way\nA screening result is only ever the beginning.
