Leaked, but at what stage? Analysis maps India's exam security weak links

Among the 17 documented paper leak cases analysed by India Today, five were traced to the printing stage, the single most common breach point. The remaining cases revealed distinct vulnerabilities across state and national examination systems.Representative image generated using AIWhen a paper leaks, the first casualty is trust. The second is time. Lakhs of candidates who spend months, and often years, preparing for competitive examinations are left waiting once again for a re-examination, a court verdict, or the outcome of an investigation. Every cancelled examination brings arrests, political blame, and promises of reform. Yet one question often remains unanswered: Where did the system actually fail?To answer that question, India Today's Open Source Intelligence (OSINT) team reviewed hundreds of reported examination integrity breaches over the past decade. Of those, 17 cases met a strict evidentiary threshold: courts or investigating agencies had officially established how and where the confidentiality of the question paper had been compromised. The dataset covers major examination integrity breaches between 2015 and 2026 that resulted in judicial intervention or official investigations and contained sufficient documentary evidence to identify the point of compromise Each of the 17 cases was mapped to the stage at which the breach occurred, from question setting and printing to packaging, transportation, district strong rooms, examination centres and computer-based testing (CBT) systems.LEAKED, BUT AT WHAT STAGE?Of the 17 examined documented paper leak cases that went till the prosecution stage, examined by India Today OSINT team, five involve national-level examinations: AIPMT (2015), SSC CGL (2017–18), CBSE Class XII Economics (2018), NEET UG (2024) and NEET UG (2026). The remaining 12 span major recruitment and entrance examinations across Bihar, Uttar Pradesh, Rajasthan, Gujarat, Uttarakhand and Jharkhand. Together, they show that vulnerabilities have emerged at nearly every stage of the examination lifecycle. Among the 17 documented paper leak cases analysed by India Today, five were traced to the printing stage, the single most common breach point The All India Pre-Medical Test (AIPMT), 2015 demonstrated that even after question papers had reached candidates, an examination could still be compromised inside the examination hall itself. In Tanvi Sarwal v. Central Board of Secondary Education & Ors. (2015), the Supreme Court reproduced the Special Investigation Team's findings that answer keys were transmitted using a "Bluetooth device to facilitate transmission of answer keys through such appliances to the users thereof," with concealed electronic devices hidden beneath clothing. Holding that the integrity of the examination had been irreparably compromised, the Court observed that "the examination has become suspect" and ordered a nationwide re-test.In the case of SSC CGL Tier II Examination (2017–18), the CBI charge sheet stated that "the computers of some candidates were remotely accessed by unknown persons with the help of software which was not supposed to be installed in the PCs of the candidates." The compromise lay within the computer-based testing infrastructure itself. Investigators also found that screenshots of examination questions had circulated on social media, exposing weaknesses in vendor oversight and CBT security. The CBSE Class XII Economics Examination (2018) highlighted another weak link: the custody of confidential question papers after they had reached the examination centre but before the test began. In Smt. Khazani Devi Educational Society v. Central Board of Secondary Education & Ors. (2019), the Delhi High Court reproduced the Deputy Commissioner of Police's investigation, which stated that the "printed question paper of Economics of XII class was leaked 1 hour before commencement of exam from Mother Khazani School, Bawana, Delhi." The investigation further recorded that teachers Rohit and Rishabh "managed to take photographs of the question paper through their mobile, prior to the start of the examination" and sent them to Md. Tauqueer. While stopping short of determining criminal guilt, the Court held that "the possibility of the examination paper having been leaked, from within the premises of the petitioner-school, cannot be irrevocably foreclosed." Major exam reform push by Judiciary, Executive and Legislative In NEET UG 2024, 2024, the Supreme Court noted that the leak at Hazaribagh and Patna was "not in dispute" and reproduced the CBI's finding that about 155 students from centres in the two cities appeared to be beneficiaries. However, after examining the movement of question papers, investigation findings and data analysis, the Court held that "there is an absence of material on the record to lead to the conclusion that the entire result of the examination stands vitiated or that there was a systemic breach in the sanctity of the examination." It therefore treated the breach as localised rather than one warranting cancellation of the examination nationwide.The NEET UG 2026 investigation gave another point of failure: authorised insider access before the paper entered the secure distribution chain. In a statement, the CBI announced that it had "identified and arrested the kingpin who was the source of the NEET UG 2026 Examination paper leak." The agency stated that PV Kulkarni, a chemistry lecturer associated with the examination process on behalf of the National Testing Agency (NTA), had access to the Chemistry paper before the examination and dictated questions, options and answers during special coaching classes.Across the 12 state-level examinations analysed, the printing stage emerged as the most common point of compromise. Official investigations traced breaches in the Bihar SSC Inter Level Examination (2017), Gujarat Head Clerk Recruitment (2020), UKPSC Recruitment (2022) and UPPSC RO/ARO Examination (2024) to printing facilities, where confidential question papers were accessed before distribution.The UP Police Constable Recruitment Examination (2024) exposed another vulnerability after printing. Investigators found that the question papers were stored at a Transport Corporation of India warehouse before dispatch, while the Enforcement Directorate alleged that the accused had entered into a criminal conspiracy to leak the papers.Insider access also emerged as a recurring vulnerability. The REET Examination (2021), described by the Supreme Court as "pertaining to leakage of the question paper and use of unfair means," exposed failures in district-level custody before the examination. Meanwhile, the Rajasthan Public Service Commission Senior Teacher Recruitment Examination (2022) revealed insider access during paper preparation within the commission.Examination centre failures surfaced in the BPSC 67th Preliminary Examination (2022), where the centre principal allegedly scanned and circulated the paper after opening the sealed packet. Logistics failures were documented in the Bihar Police Constable Recruitment Examination (2023), where confidential courier movement data was copied and supplied to the leak network before the papers reached examination centres.INDIA'S RESPONSE TO PAPER LEAKS "No encryption can stop a question paper setter from leaking the paper," V. Kamakoti, IIT Madras Director and a member of the Nandan Nilekani-led High-Powered Committee on examination reforms, told India Today while reflecting on the NEET UG 2026 controversy.The latest measures being taken towards examination reforms follow the NEET UG 2026 paper leak, which triggered weeks of protests by students and the Cockroach Janta Party (CJP), while Opposition parties demanded accountability, culminating in the resignation of Union Education Minister Dharmendra Pradhan.The government's response builds on more than a decade of institutional reforms. Since the Supreme Court's intervention in the AIPMT paper leak case in 2015, India's approach has evolved across all three branches of governance. The judiciary laid down key legal principles on examination integrity through its landmark rulings in the AIPMT (2015) and NEET UG (2024) cases. The executive established the National Testing Agency, constituted the Dr K Radhakrishnan High-Level Committee in 2024 and, more recently, the Nandan Nilekani-led High-Powered Committee in 2026. Parliament enacted the Public Examinations (Prevention of Unfair Means) Act, 2024 and has since introduced an Amendment Bill to strengthen penalties, investigations and trials.Many of the Dr K. Radhakrishnan Committee's 101 recommendations align with the vulnerabilities identified in the India Today analysis, calling for stronger safeguards across every stage of the examination lifecycle – from question paper setting and printing to transportation, computer-based testing, vendor oversight and institutional governance. While several recommendations have been implemented, others remain a work in progress.- EndsPublished By: bidisha sahaPublished On: Jul 28, 2026 16:42 IST
