The NEET-UG 2026 controversy has become one of the biggest education scandals in recent years. More than 22 lakh students appeared for the National Eligibility cum Entrance Test (NEET-UG) on May 3, 2026, hoping to secure admission to medical colleges across India. However, just nine days later, the National Testing Agency (NTA) cancelled the exam after investigators found evidence that the question paper had been leaked.
This was the first time in NEET’s history that the examination was cancelled due to a paper leak. Following the decision, the NTA announced a re-examination on June 21, 2026. The incident has raised serious questions about exam security and the functioning of the country’s testing system.
Multi-State Network Behind the Paper Leak
Investigations revealed that the leak was not limited to one state. Authorities found evidence of a large network operating across Rajasthan, Maharashtra, Haryana, Kerala, and Bihar.
According to investigators, leaked question papers were allegedly sold to students for amounts ranging from ₹2 lakh to ₹25 lakh. In Rajasthan, a chemistry teacher from Sikar alerted authorities after noticing that a “guess paper” circulating before the exam looked very similar to the actual question paper. The investigation later found that around 120 to 140 questions matched the real paper exactly.
The Central Bureau of Investigation (CBI) arrested several people in connection with the case. Among them was Manisha Sanjay Havaldar, a Pune school principal and an NTA-appointed Physics expert. Investigators alleged that she reconstructed exam questions from memory and shared them with students. Another accused, botany lecturer Manisha Gurunath Mandhare, was also linked to the operation.
In Maharashtra’s Latur district, coaching institute owner Shivaraj Motegaonkar was arrested for his alleged involvement in the leak. The CBI also arrested chemistry professor P.V. Kulkarni, who is accused of conducting special sessions where exact exam questions were reportedly shared with selected students.
In Bihar, police uncovered another part of the network. Investigators found that several students had been gathered in a rented house before the exam, where they were allegedly given leaked questions to memorise. Statements from the accused helped investigators understand how the leaked paper was distributed before the examination.
Telegram Comes Under Government Action
The controversy also brought Telegram into the spotlight. Investigators claimed that scammers were misusing Telegram’s message-editing feature to create fake proof of question paper leaks.
According to officials, fraudsters would post messages before the exam and later edit them to attach fake question papers after the test was over. Since the original timestamp remained unchanged, it created the false impression that the paper had been leaked earlier. These scams reportedly convinced many students and parents to pay large amounts of money for fake papers.
To prevent further misuse, the Ministry of Electronics and Information Technology (MeitY) reportedly ordered a temporary block on Telegram in India from June 16 to June 22, covering the period before the NEET re-exam. The government also directed Telegram to disable its message-editing feature for Indian users until June 30.
The decision sparked debate. Digital rights groups argued that restricting the platform affected millions of genuine users while failing to address the real issue of exam leaks. Telegram also criticised the move, saying that those involved in illegal activities could simply switch to other apps.
At the same time, students faced problems related to fee refunds after the exam cancellation. Some candidates claimed they missed refund deadlines because the verification process was linked to downloading re-exam admit cards. The issue led to criticism from political leaders and student groups, prompting the NTA to reopen the correction and verification process.
Supreme Court Criticism and Future Changes
The NEET-UG 2026 leak has attracted even more attention because similar concerns were raised during previous examination cycles. Many critics questioned why earlier recommendations to improve security were not fully implemented.
During hearings on the matter, the Supreme Court reportedly criticised the handling of examination security and expressed concern that lessons from past controversies had not been properly applied. A Parliamentary Standing Committee also highlighted repeated problems in several NTA-conducted examinations and called for urgent reforms.
In response, the government has moved ahead with stricter measures to prevent future leaks. The Public Examinations (Prevention of Unfair Means) Act, 2024, has now been notified, allowing authorities to impose tougher punishments on organised exam fraud. Under the law, offenders can face up to 10 years in prison and fines of up to ₹1 crore.
The government has also announced that NEET will shift completely to a Computer-Based Test (CBT) format from 2027. Experts believe this change could significantly reduce the chances of question paper leaks.
Other proposed reforms include biometric verification of candidates, GPS tracking of examination materials, and conducting exams in multiple shifts to improve security.
As students prepare for the NEET-UG 2026 re-examination, the controversy has once again highlighted the need for a fair, transparent, and secure examination system. The results of the ongoing investigation and the success of upcoming reforms will be closely watched by millions of students, parents, and educators across the country.
