The Indian Scale for Assessment of Autism (ISAA) is a 40-item clinician-rated assessment tool developed in India to evaluate the severity of autism and determine disability in children and young adults.
It uses structured observation and caregiver interviews across six developmental domains:
ISAA scores range from 40 to 200.
Not Autism
Mild Autism
Moderate Autism
Severe Autism
The assessment usually takes 15 to 20 minutes, requires minimal specialized training, and is available free of cost in multiple Indian languages.
Studies have shown excellent reliability and validity with high internal consistency (Cronbach’s Alpha approximately 0.93 to 0.97). However, it is less accurate for children below five years of age and may not clearly distinguish autism from other neurodevelopmental disorders such as ADHD or intellectual disability.
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by:
Early assessment is essential for timely intervention.
The Indian Scale for Assessment of Autism (ISAA) was developed by the National Institute for the Empowerment of Persons with Intellectual Disabilities (formerly NIMH) specifically for Indian populations.
Unlike many international assessments, ISAA is:
The assessment combines:
Each of the 40 items is scored on a scale of 1 to 5, producing a total score between 40 and 200.
The ISAA was designed to:
Under the Rights of Persons with Disabilities (RPWD) Act, autism is recognized as a disability.
ISAA scores are also converted into disability percentages for government certification.
ISAA has been validated for individuals aged 3 to 20 years.
It can be used across varying intellectual abilities, including children with coexisting intellectual disability.
However, research suggests:
Therefore, clinicians interpret results cautiously in younger children.
The assessment is conducted by trained professionals such as:
The clinician observes the child’s:
Parents answer questions regarding their child’s:
Each of the 40 items receives a score from:
1 = Rarely or Never
5 = Always
The complete assessment generally requires 15 to 20 minutes.
The total score ranges from 40 to 200.
Does not meet autism criteria.
Mild Autism.
Moderate Autism.
Severe Autism.
Higher scores indicate greater severity.
ISAA results should always be interpreted alongside clinical judgment and additional assessments.
Research has demonstrated strong psychometric performance.
Studies report:
ISAA has shown:
Receiver Operating Characteristic (ROC) analysis has demonstrated excellent diagnostic accuracy.
Despite being developed specifically for the Indian population, ISAA offers several advantages.
Developed specifically for Indian children and available in multiple regional languages.
Usually completed within 15 to 20 minutes.
Available without licensing fees through the National Trust.
ISAA evaluates:
Validated across Indian clinical populations.
Officially accepted for disability certification.
Despite its advantages, ISAA has several limitations.
Less effective for toddlers and preschool children below five years.
Children with:
may receive elevated scores despite not having autism.
Children with subtle social communication difficulties may receive lower scores than expected.
Internationally, assessments such as ADOS-2 and ADI-R remain the gold standard for autism diagnosis.
ISAA should always be used alongside a comprehensive clinical evaluation.
ISAA was designed specifically for Indian healthcare settings.
Its advantages include:
Many government hospitals and autism centers use ISAA for official assessments.
ISAA helps clinicians:
Families can use ISAA reports for:
Parent notices developmental concerns.
⬇️
Primary evaluation by a Pediatrician or General Practitioner.
⬇️
Referral to a Developmental Pediatrician, Psychiatrist, or Child Psychologist.
⬇️

Approximately 15 to 20 minutes.
The ISAA itself is free.
Families only pay the consultation fee charged by the evaluating professional.
Children may benefit from periodic reassessment to monitor progress.
Approximately 3 to 20 years, although caution is advised for children younger than five years.
