Indian Scale for Assessment of Autism
What is the Indian Scale for Assessment of Autism (ISAA)?
The Indian Scale for Assessment of Autism (ISAA) is a clinician-administered, India-standardised tool used to assess and describe autism, and is the instrument used officially in India for autism disability certification. It rates a child across domains including social relationships, emotional responses, speech and communication, behaviour patterns, sensory aspects and cognitive components. ISAA is a structured, descriptive map of a child's profile, not a verdict on potential, and is always used by a trained professional as part of a wider developmental evaluation.
A made-in-India tool that helps clinicians describe autism in a structured, culturally-grounded way — that is the ISAA.
In short
The Indian Scale for Assessment of Autism (ISAA) is a clinician-administered instrument developed in India to help assess and describe autism in children and adults. It was created by the National Institute for the Mentally Handicapped (now NIEPID) and is the tool officially used in India for certifying autism for disability benefits. ISAA does not replace a clinician's judgement — it gives a structured, observation-based way to record the pattern and degree of autism-related traits across several areas of behaviour.What the ISAA assesses
ISAA looks at a child across several domains of everyday behaviour rather than a single skill. These cover social relationships and reciprocity, emotional responses, speech, language and communication, behaviour patterns (such as repetitive actions, routines or unusual interests), sensory aspects (how a child responds to sound, touch, light or movement), and cognitive components (attention, memory and thinking). A trained professional observes and rates each item, building a profile that reflects how strongly these traits are present and how much they affect daily life.Because it was standardised on Indian children, ISAA uses examples and expectations suited to Indian family and cultural contexts — one reason it sits at the centre of India's autism certification process. It is best understood as a descriptive, supportive map of a child's profile, not a verdict on potential. Every child it describes is a child who can grow with the right, individualised support.
When it is used
ISAA is administered by a qualified clinician or psychologist, usually as part of a wider developmental evaluation that also draws on parent history, direct observation and other assessments. Families often encounter it when seeking a formal autism assessment or a disability certificate. If you have noticed differences in your child's communication, play, social connection or responses to the world, the right next step is a developmental review with a clinician — who will choose the most appropriate tools for your child.The Pinnacle way
This is general information, not a diagnosis — a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form. Our clinicians understand instruments like the ISAA and weave assessment into a warm, whole-child picture, then build an individualised plan that may draw on speech therapy and other supports.Trusted sources

What to watch
Differences in social connection and eye contact, delayed or unusual speech and communication, repetitive behaviours or strong routines, and unusual responses to sounds, touch or light — these are the kinds of areas a clinician explores, not items for parents to score at home.
Try this at home
You don't need to assess your child yourself — instead, jot down everyday observations about how your child communicates, plays and responds to the world, and share these notes with your clinician to make any assessment richer and more accurate.

Frequently asked
Who can administer the ISAA?
ISAA is administered by a qualified clinician or psychologist trained in its use, usually as part of a broader developmental evaluation that also includes parent history and direct observation. It is not a self-test for parents to complete at home.
Is the ISAA used for autism certification in India?
Yes — ISAA was developed and standardised in India and is the instrument used officially in the Indian disability-certification process for autism. A clinician interprets the results within a wider clinical picture.
What areas does the ISAA cover?
It covers social relationships and reciprocity, emotional responses, speech and communication, behaviour patterns such as repetition and routines, sensory responses, and cognitive components like attention and memory.
Does an ISAA result decide my child's future?
No. ISAA is a descriptive map of a child's current profile, not a verdict on potential. Every child it describes can grow with the right, individualised support.
