Bhatia's Battery of Performance Tests of Intelligence (Bhatia Battery)
A clinician's overview of Bhatia's Battery of Performance Tests of Intelligence, a non-verbal Indian intelligence battery. Its five subtests, what it measures, and where it fits in Indian practice.

What it is
The Bhatia Battery, developed by C.M. Bhatia in 1955, is a non-verbal, performance-based intelligence test standardised for the Indian population. It was designed so that a person's literacy and language would not limit the result, which made it well suited to a country with wide variation in schooling.
It is made up of five performance subtests and yields an estimate of intelligence based on time and accuracy.
What it covers
| Koh's Block Design Test | Reproducing geometric designs with coloured cubes; samples spatial and constructional reasoning |
|---|---|
| Alexander's Pass-Along Test | Sliding coloured blocks into a target arrangement within a frame; samples planning and problem-solving |
| Pattern Drawing Test | Copying patterns in one continuous line, without lifting the pen or retracing |
| Immediate Memory Test | Repeating sequences of digits forward and backward; samples short-term and working memory |
| Picture Construction Test | Assembling cut-up pictures into a whole; samples visual synthesis |
If this test was given to you or your child
If you or your child has been referred for the Bhatia Battery, this is what the session looks like. You sit with a psychologist and work through five practical tasks — arranging coloured blocks to match a design, sliding blocks into a pattern, copying drawings, repeating sequences of numbers, and putting cut-up pictures back together. It usually takes about 40 to 60 minutes.
The striking thing about this test is that there is almost no reading, writing or talking involved. It was built that way on purpose, in 1955, so that someone with little formal schooling would not be marked down for it. If you have been worried that a test would really be testing your English or your education rather than your ability, this is the test designed around exactly that concern.
You are timed on some tasks. That is normal and it is part of how the test works, not a sign that you are being rushed or judged.
Reading the results
The report gives an estimate of intelligence based on how accurately and how quickly the tasks were done. Because the tasks are practical rather than verbal, the result describes reasoning with shapes, patterns and sequences — not vocabulary, general knowledge or how well someone reads.
That makes it useful in a specific way and limited in another. A good result here says something real about problem-solving ability. It does not tell you how someone will cope with a heavily language-based school or job. A careful psychologist will say which of those questions was being asked, and will often use a second test alongside this one.
The norms behind this battery are old, dating from the 1950s. Clinicians take that into account when interpreting a score, and so should you when reading one.
What it cannot tell you
It does not diagnose anything on its own. It is one measure of one kind of ability, taken on one day.
It cannot tell you whether someone has a learning difficulty, autism or ADHD, though it is sometimes used as one part of assessing those. It does not measure memory for everyday life, emotional wellbeing, motivation or how someone copes under pressure.
And it does not measure potential. A low score on a timed block-design task on a difficult afternoon is a snapshot, not a ceiling. If the person was unwell, exhausted, anxious or unfamiliar with the examiner, say so — it belongs in the report.
Who can administer it in India
The Bhatia Battery is a published, restricted instrument. It should be administered and scored by a psychologist trained in it, working from the manual and the physical materials.
Timing and handling of the blocks are part of the standardisation, which is why it cannot be done informally or from a description. If you are unsure who assessed you or under whose supervision, it is reasonable to ask.
Where to get assessed
Government medical colleges, district hospitals with psychiatry or clinical psychology departments, and District Early Intervention Centres carry out assessments at low or no cost, with waiting times that vary by district. Private clinics and hospitals charge a fee that varies by city.
If the assessment is needed for disability certification, a school accommodation or a job requirement, check which route the receiving authority accepts before you book. Requirements differ, and a report from the wrong setting can mean doing the whole thing again.
Who it is for
It is used where a non-verbal, performance-based estimate of intelligence is helpful, including with clients who have limited literacy or formal education, and in settings where language-loaded tests would be unfair.
It is administered individually by a trained examiner, with careful timing.
For clinicians
How it is administered
The examiner administers the five subtests in order, recording time and accuracy, and converts performance to a mental age and IQ estimate using the battery's norms.
The materials are obtained through the publisher; the items are not circulated openly.
Use in India
The Bhatia Battery remains a staple in Indian clinical practice, particularly for assessing intelligence in people with low literacy, and is often used alongside verbal tests or as part of intellectual disability assessment. As with other older Indian tests, clinicians keep the age of the norms in mind.
In Hindi-medium teaching and practice it is often referred to as the Bhatia Battery Parikshan (भाटिया बैटरी परीक्षण), and it appears on the syllabus of most Indian psychology degrees, which is why so many students look it up by subtest name.

Frequently asked questions
Five performance subtests: Koh's Block Design, Alexander's Pass-Along, Pattern Drawing, Immediate Memory (digit span), and Picture Construction.
It is non-verbal and performance-based, so it does not depend on literacy or language. That makes it well suited to Indian clients with varied schooling.
A trained examiner, working individually with the client and timing each subtest. The materials are obtained through the publisher.
It measures non-verbal, performance-based intelligence — reasoning with blocks, patterns, digit sequences and pictures — and yields a mental age and an IQ estimate. It deliberately leaves out language and reading, so it reflects problem-solving ability rather than vocabulary, general knowledge or schooling.
It was standardised on individuals aged roughly 11 to 16 years. In Indian practice it is used more widely, including with adults, when a non-verbal estimate is needed, and results outside the standardised ages are read with added caution.
Performance on each subtest is scored from time and accuracy, and the subtest scores combine into a mental age and IQ estimate using the battery's norms. The detailed scoring tables are in the restricted manual.
The manual, blocks and scoring materials are restricted and are sold by psychological-test publishers in India (for example Prasad Psycho) to qualified professionals. ElloMind does not provide the manual, the items or the scoring keys; this page is an educational overview only.
When literacy, schooling or language would unfairly limit a verbal test result: clients with little formal education, a language barrier with the examiner, or hearing and speech difficulties. It is also used to complement a verbal test so both sides of ability are sampled.
It was standardised on school-age groups, but in practice it is used more widely, including with adults, especially where a non-verbal estimate is needed. Results outside the normed ages are interpreted with corresponding caution.
