# How does the ISAA compare with the AbilityScore developmental assessment? Canonical: https://pinnacleblooms.org/ask/how-does-the-isaa-compare-with-the-abilityscore-developmental-assessment Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited The ISAA and the AbilityScore® answer different questions. The ISAA is a government-recognised tool used mainly to certify autism and assign a disability percentage for entitlements. The AbilityScore® is a clinician-administered structured assessment that maps abilities across developmental domains to build and track a personalised therapy plan. They complement rather than replace each other, and any diagnosis is confirmed only by a qualified Pinnacle clinician. *You may have heard of the ISAA at a government hospital and wondered how it sits alongside Pinnacle's AbilityScore® — here's a clear, gentle comparison.* ## In short The [Indian Scale for Assessment of Autism (ISAA)](/isaa) and the AbilityScore® serve two different purposes. The ISAA is a government-recognised tool used mainly to certify autism and decide disability percentage for entitlements; the AbilityScore® is a clinician-administered structured assessment that maps your child's abilities across many developmental areas to build a personalised therapy plan and track progress over time. They complement each other — one supports official certification, the other guides everyday growth. ## How the two compare Think of them as answering different questions about your child. - **What it's mainly for** — The ISAA was designed to assess severity of autism and assign a disability percentage, which is used for the official disability certificate and related benefits in India. The AbilityScore® is designed to understand *how your child is developing across domains* — communication, social skills, play, motor, daily living and more — so therapy can be tailored and measured. - **What it covers** — The ISAA focuses specifically on autism-related behaviours. The AbilityScore® looks broadly at strengths and emerging skills across development, whatever the underlying picture, so the plan fits the whole child. - **How often it's used** — An ISAA certification is typically a periodic, formal exercise. The AbilityScore® is repeated over a journey, giving a living baseline you can watch progress against session by session. - **Who administers it** — The ISAA is administered by authorised professionals at recognised centres for certification. The AbilityScore® is administered by qualified Pinnacle clinicians as part of a therapy pathway. Neither tool replaces the other. Many families use an ISAA-based certificate to access entitlements *and* an AbilityScore® to drive day-to-day therapy goals. ## When each one helps If you need an official disability certificate or access to government schemes and entitlements, the ISAA route at an authorised centre is the appropriate one. If you want a clear, ability-focused picture to start or fine-tune therapy and measure your child's growth, the AbilityScore® is built for that. Choosing one does not rule out the other. ## The Pinnacle way Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of a qualified clinician — never from an online figure or a form. The AbilityScore® is a clinician-administered structured assessment that measures your child against *their own* baseline, turning observation into a practical plan. Backed by 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, our clinicians pair assessment with focused support such as [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) and tailored learning goals.
