When the 2026 gaokao began on June 7, China switched on the most elaborate exam-security apparatus in the world. Roughly 12.9 million candidates sat the national college entrance exam across 7,981 testing centers and some 348,000 exam rooms, according to China's Global Times. Inside and around those venues, authorities deployed signal jammers, AI-powered behavioral monitoring, upgraded security gates designed to detect concealed wearables, and a blanket ban on phones, smartwatches, smart bands, and smart glasses.
The lockdown landed the same month digital-rights groups escalated a global fight against exactly this category of intervention. Access Now's #NoExamShutdown campaign — run with the Internet Society and the Lebanese group SMEX — spent the spring documenting governments that cut national connectivity during school exams, and on May 12, 2026 the Electronic Frontier Foundation published "A Hackers Guide to Circumventing Internet Shutdowns." The juxtaposition is irresistible — but it conflates two very different things, and the difference is the whole argument.
Two kinds of exam-time blackout
The shutdowns Access Now tracks are blunt instruments. Sudan ran roughly ten nationwide blackouts over eleven days during its April secondary-school exams — a sixth consecutive year. Iraq suspended internet service for the entire country between 6:00 and 7:30 a.m. on June 2. These are population-wide kill switches: every hospital, bank, business, and family loses connectivity so that some teenagers cannot cheat. Access Now counted 313 shutdowns across 52 countries in 2025, the highest total since it began monitoring in 2016, and notes that exam-related orders are now a leading driver of the global trend.
China's gaokao regime is architecturally different. The signal jamming is geographically bounded to exam halls; the device screening happens at the door; the AI monitoring watches inside the room. The general public's mobile internet keeps working. A jammer that suppresses radio frequencies inside one building for a few hours is a narrow, time-and-place-limited measure. A nationwide internet order that darkens a country of 40 million is not. One can object to both, but only one of them imposes catastrophic collateral cost on people who have nothing to do with the exam.
The strongest case for the controls
The case for aggressive exam integrity deserves a fair hearing. The gaokao is close to a single-shot determinant of life outcomes for hundreds of millions of families, which makes the incentive to cheat — and the market for covert earpieces, camera-glasses, and AI answer services — enormous. In recent years major Chinese platforms including Alibaba, ByteDance, and Tencent temporarily disabled the photo-recognition and question-answering functions of chatbots like Qwen, Doubao, and Kimi during exam hours, as Interesting Engineering reported. When the stakes are that asymmetric and the cheating tools that sophisticated, a localized, scheduled suppression of wireless transmission inside the exam hall is a defensible response — far more so than a province-wide blackout, and arguably the most proportionate tool available for the actual threat.
Where China's version still overreaches
Proportionate in form does not mean proportionate in substance. Two features of the 2026 regime should worry anyone committed to the open internet.
First is the strict-liability framing. Provincial rules cited by Global Times state that "bringing mobile phones, smartwatches, smart bands, smart glasses, or other devices into gaokao exam rooms constitutes cheating, regardless of whether the devices are actually used" — possession alone cancels a score. Punishing a forgotten smartwatch as severely as an active cheating rig is the kind of zero-tolerance design that sacrifices fairness to administrative convenience.
Second is the normalization of pervasive behavioral surveillance. China's AI monitoring systems "automatically flag unusual behavior by test takers and generate video clips for further review" — whispering, irregular eye movement, fidgeting. Algorithmic suspicion-scoring of minors, even for a defensible purpose, builds infrastructure and habits that rarely stay confined to their original use. The pattern across surveillance technology is that capability built for an emergency becomes the everyday baseline.
Why the distinction matters for policy
The instinct to lump China's jammers in with Iraq's national blackout is understandable but counterproductive. A coherent free-expression position is not "no government may ever suppress a radio signal." It is that restrictions on connectivity must be necessary, proportionate, time-limited, and narrowly targeted — the standard international human-rights law already demands. By that test, a jammer running for three hours inside an exam hall can pass; cutting a whole nation's internet to police the same exam cannot. The EFF and Access Now toolkits — Meshtastic mesh radios, Briar's Bluetooth routing, satellite links — exist precisely because the population-wide variant is so destructive that citizens need offline fallbacks to function.
The better lesson from June 2026 is comparative. China demonstrates that a state determined to secure an exam has narrow, surgical options that leave the broader network intact. That removes the last excuse from governments in Khartoum, Baghdad, and Algiers, whose national blackouts are not the only way to stop cheating — merely the laziest and most rights-corrosive. The fight Access Now and EFF are waging is winnable not by banning every jammer, but by holding the line that scale and targeting are the whole question. China's gaokao, for all its excesses, makes that line easier to draw.
