Can moving India's biggest entrance examinations from pen and paper to computers finally break the country's seemingly endless cycle of exam question leaks?
asserted
moving → publish → leaks
The issue gained fresh urgency after weeks of protests over the National Eligibility cum Entrance Test (NEET) medical entrance exam forced the resignation of education minister Dharmendra Pradhan.
asserted
weeks → gain → Pradhan
Protesters say more than 20 students died by suicide, with their families blaming the exam scandal for their deaths.
asserted
families → say → deaths
Prime Minister Narendra Modi responded by appointing an expert task force headed by Nandan Nilekani of the Indian IT giant Infosys to overhaul the National Testing Agency (NTA), which runs the exam.
asserted
which → respond → exam
Modi recommends, external shifting the tests to computer-based testing (CBT) to make them more secure.
asserted
them → recommend → testing
Hearing petitions on the reforms, the Supreme Court welcomed the government's efforts but cautioned that computer-based testing (CBT) alone would not eliminate the risk of exam paper leaks.
asserted
testing → hear → leaks
That warning captures the challenge facing the task force: can technology fix what is ultimately a problem of trust, governance and incentives?
asserted
what → capture → trust
The contrasting NEET paper leaks of 2024 and 2026 illustrate why the answer is more complicated than simply digitising exams.
asserted
answer → contrast → exams
NEET uses four versions of the question paper, each containing 180 compulsory questions across physics, chemistry and biology.
asserted
each → use → physics
The leaks occurred at opposite ends of the exam process.
asserted
leaks → occur → process
In 2024, the paper was allegedly leaked after printing, when sealed trunks were opened during transit to exam centres.
uncertain
trunks → leak → centres
Investigators said the breach was limited, involving about 40-50 people, and the Supreme Court ruled the exam's overall integrity remained intact, rejecting calls for a re-test.
asserted
integrity → say → test
In 2026, the leak allegedly happened before the paper left the NTA, with teachers accused of leaking it from within the system.
uncertain
teachers → happen → system
Officials say the safeguards on printing, transport and distribution held up.
asserted
safeguards → say → printing
The vulnerability lay at the source, before the secure chain of custody even began.
asserted
chain → lie → custody
For Prof V Kamakoti, director of Indian Institute of Technology (IIT) Madras and a member of the task force, the two episodes expose where trust in an examination system ultimately resides.
asserted
trust → expose → system
"The roots of trust lie in two places: the teachers who set the question papers and the invigilators who supervise candidates.
asserted
who → lie → candidates
If either is compromised, the system is vulnerable," he told the BBC.
asserted
he → compromise → BBC
Officials have proposed extensive CCTV surveillance, with live feeds monitored from central control rooms.
asserted
feeds → propose → rooms
Kamakoti says AI could go further, automatically flagging suspicious behaviour - such as prolonged conversations between invigilators and candidates - so officials can intervene in real time.
uncertain
officials → say → time
"At least the invigilator part we can certainly handle.
asserted
we → handle → ?
But he argues that the bigger leap in security lies in moving exams online.
asserted
leap → argue → exams
Computer-based testing, he says, would make India's examinations far more secure.
asserted
examinations → base → ?
"Compromising the technology would be extremely difficult," he said, pointing to more than a decade of experience running large-scale computer-based examinations..
asserted
he → compromise → examinations
IIT Madras manages Swayam, the Indian government's online learning platform, and has extensive experience conducting large-scale computer-based examinations, including Graduate Aptitude Test in Engineering (GATE) and advanced Joint Entrance Examination (JEE), required for admission to the country's top engineering colleges.
asserted
Madras → manage → colleges
These systems, Kamakoti says, rely on "red teaming" - teams that constantly probe systems for weaknesses - and "air-gapped" networks physically isolated from the internet.
asserted
that → say → internet
"No one can hack into that network," he says.
"
asserted
he → hack → network
The systems are designed to withstand technical failures.
asserted
systems → design → failures
If a computer crashes or power fails, the timer pauses automatically and resumes on another machine."
But even the most secure technology cannot eliminate the human factor.
asserted
technology → crash → factor
For Kamakoti, that is where the examination system's "root of trust" lies.
asserted
root → lie → trust
"The biggest challenge is to get trusted question setters," he says.
asserted
he → trust → setters
Preparing a NEET paper is a complex exercise.
asserted
Preparing → prepare → paper
The exam is conducted in 13 languages, including English, making it one of the world's largest multilingual entrance examinations.
asserted
it → conduct → examinations
It requires subject experts, translators, reviewers and moderators.
asserted
It → require → experts
Kamakoti estimates that around 50 people may be involved in setting papers.
uncertain
people → estimate → papers
"If even one person in that entire set is compromised, we are gone," he said.
asserted
he → compromise → set
Computer-based testing removes one major vulnerability by eliminating the need to print, transport and store millions of question papers.
asserted
testing → base → papers
So why hasn't NEET already gone digital?
asserted
NEET → go → ?
Kamakoti says NEET has remained a paper-based exam, where answers are shaded on machine-readable answer sheets, because it is conducted in a single session for all candidates to ensure fairness.
asserted
it → say → fairness
India can currently accommodate only about 300,000 candidates in one computer-based testing session, far short of NEET's 2.2 million test-takers, he says.
asserted
he → accommodate → takers
…and 30 more, not listed.
