The machine itself had become part of the test
In late January, Brazil took its first step toward a fully digital national university entrance exam, gathering 93,000 students across 104 cities in a pilot that revealed both the promise and the fragility of that ambition. The screen, it turns out, is not a neutral surface — it carries the weight of infrastructure inequality, bodily fatigue, and the quiet anxiety of a nation still navigating a pandemic. What the pilot confirmed is not simply that the digital format can work, but that making it work equitably will demand far more than a change in medium.
- Ninety-three thousand students sat for Brazil's first digital Enem, but the experience split sharply between those who found the screen liberating and those who found it an obstacle in itself.
- Older, sluggish computers at some testing sites turned the exam into an endurance test of a different kind — not of knowledge, but of patience and physical strain.
- The pandemic quietly shaped the experience too, with reduced room capacity offering an unexpected sense of safety, even as some regions suspended testing entirely due to local outbreaks.
- Small interface failures — accidental logouts, unfamiliar navigation — cost students time and confidence, exposing how even well-designed systems can falter under real-world pressure.
- Brazil's goal of a fully digital Enem by 2026 now rests on a clearer, harder truth: standardizing equipment and refining usability are not technical footnotes, but prerequisites for fairness.
Brazil held its first pilot digital Enem on a Sunday in late January, with 93,000 students sitting for the exam across 104 cities — a small but telling fraction of the 2.5 million who had taken the traditional paper version in previous weekends. The impressions they carried out were sharply divided.
For some, the digital format was a genuine improvement. An eighteen-year-old from Rio de Janeiro found that navigating on screen helped him hold his place in ways paper never had. A classmate described the experience as almost enjoyable, and both noted an unexpected benefit of the pilot's lower turnout: fewer bodies in the room meant a safer, calmer space during the pandemic.
But the experience fractured along infrastructure lines. A nineteen-year-old in São Bernardo do Campo sat at an old, sluggish machine where pages loaded slowly and hours of screen reading left him drained. He saw potential in the format — but only if the equipment improved. Teachers who administered or took the exam echoed this. One education director in Fortaleza accidentally logged himself out mid-test despite having watched the tutorial. A history teacher from Niterói found the system stable but felt the screen wear on him; he recovered only when he reached the essay, still written by hand on paper, though the computer left barely enough desk space to do it.
The digital and paper versions used different questions, but were statistically calibrated to the same difficulty so students could compete fairly for the same university seats. The government's target is one hundred percent digital by 2026. The pilot made clear what that will require: not just more computers, but better ones — and interfaces that hold up under the pressure of a high-stakes exam and a tired human body.
The exam proceeded under pandemic protocols, with masks, reduced capacity, and hand sanitizer at every site. Some regions suspended testing due to local outbreaks, and roughly twenty lawsuits had challenged whether the exam should proceed at all. It did. And now Brazil has something more valuable than a plan — it has evidence of where the plan must grow.
Brazil held its first pilot version of the digital Enem—the national university entrance exam—on a Sunday in late January, and the students who took it came away with sharply divided impressions. Some found the experience liberating, even pleasant. Others left exhausted, frustrated by the weight of staring at a screen for hours, or hampered by machines so old and slow that the test itself became an obstacle course. Ninety-three thousand people sat for the digital version across 104 cities, competing for university spots alongside 2.5 million others who had taken the traditional paper exam the previous weekends.
Francisco Erick Lima, eighteen, walked out of his testing center in Rio de Janeiro convinced that the computer had been the right choice. He had worried the system would crash—a reasonable fear for a pilot program—but it held steady. On paper, he said, he lost his place constantly, scanning back and forth through the pages. On screen, he found his bearings. He moved through the test with confidence, and he was not alone in that feeling. Anna Marya Freitas, also eighteen and also from Rio, described the experience as almost enjoyable. She stood up once to wash her face, felt alert throughout, and found the exam itself manageable. Both students had been nervous about the pandemic—Lima lived with people in high-risk groups, Freitas was herself at risk—but the digital format had brought an unexpected benefit: fewer bodies in the room. Where twenty students had been expected at Lima's site, only eight showed up. The emptiness made the space feel safer.
But the experience fractured along a fault line of infrastructure. Kleverton Launé, nineteen, a veteran test-taker who sat for the Enem annually to track his own progress, chose the digital version this year to see what it was like. He took it at a school in São Bernardo do Campo, outside São Paulo, on a computer that was old and sluggish. Pages took forever to load. Reading from the screen for hours left him drained. He wore glasses; he imagined the strain would be worse for those who did not. The machine itself had become part of the test, and not in a good way. He saw potential in the digital format, but only if the equipment improved.
Teachers who administered or took the exam reported similar mixed reactions. Ademar Celedônio, an education director who sat for the test in Fortaleza, praised the structure—it matched the Enem standard, nothing jarring or unfamiliar. But the interface tripped him up. He had watched the tutorial. Still, when he sat down, muscle memory failed him. He hit the wrong button, logged out by accident, had to log back in. It was not catastrophic, but it cost him time and focus. After two hours, he closed his eyes and rested. His head barely moved during the first day of testing—just eyes scanning, hand reaching for the mouse to scroll. The screen itself was the fatigue.
Rômulo Braga, a history teacher from Niterói, found the system intuitive enough, and it did not freeze or lag. But the screen wore on him too. He recovered by writing the essay—the one part of the exam still done by hand, on paper, just as it had always been. The essay topic that year was the challenge of reducing inequality between Brazil's regions, and Braga thought it was excellent: broad, critical, rich with possibility for a student who knew some geopolitics. Writing it felt the same as the paper version, same scratch paper, same process. What threw him off was the desk itself. With the computer taking up space, there was barely room to write.
The digital Enem used different questions than the paper version, but calibrated them to the same difficulty level using a statistical method called item response theory, so that students taking either format would compete fairly for the same university seats. The government's plan is ambitious: one hundred percent digital by 2026. But the pilot revealed what would have to change. Equipment matters. Older machines slow the test down and drain the tester. Usability matters—even small interface confusions cost time and confidence. And the human body matters. Hours at a screen is not the same as hours with paper, no matter how well the test is designed.
The exam went forward despite the pandemic, with masks required, reduced capacity in each room, and hand sanitizer at every site. Students showing symptoms were told to stay home and could retake the test in late February. Some regions—parts of Amazonas, Rondônia—suspended testing altogether due to local pandemic impacts. About twenty lawsuits had been filed across the country challenging whether the exam should happen at all. But it did, and now Brazil knows what works and what does not. The next step is scaling up, and that will require not just more computers, but better ones.
Citas Notables
On paper I lose my place constantly. On the computer I found my bearings and didn't get lost in anything.— Francisco Erick Lima, 18-year-old test-taker
The computer was old and slow, the page transitions were slow. It was tiring to read from the screen. I think there's a lot that needs to improve.— Kleverton Launé, 19-year-old test-taker
La Conversación del Hearth Otra perspectiva de la historia
What surprised you most about how students reacted to the digital format?
That it split so cleanly along one line: the quality of the machine they used. The students who took it on decent equipment felt liberated. The ones on old, slow computers felt trapped. It wasn't about digital versus paper—it was about whether the technology got out of the way or became the test itself.
Did anyone actually prefer it to paper?
Yes, genuinely. The students who said they usually lose their place on paper found the screen easier to navigate. And there was something else: the lower turnout meant less crowding, which mattered a lot to people worried about the pandemic. Fewer bodies in the room felt safer.
What about the fatigue issue? Is that just a matter of getting used to it?
Maybe partly. But even the teachers who administered it—people used to screens—felt it. Your eyes and neck work differently when you're reading from a monitor for hours. One teacher said he had to close his eyes and rest after two hours. That's real, not just adjustment.
The government wants this fully digital by 2026. Is that realistic?
Only if they solve the equipment problem first. You can't scale this up with old machines. And the interface needs work—even trained educators hit the wrong buttons and lost time. Those are solvable problems, but they have to be solved before you push this to millions of students.
What did the essay portion tell you?
That some things shouldn't change. Writing by hand on paper felt natural to everyone. The moment they had to do it at a desk with a computer taking up half the space, it became awkward. Sometimes the old way works.
So what's the real story here?
It's about infrastructure meeting ambition. Brazil has a good idea—digital testing can be fairer, more accessible eventually. But you can't get there with the equipment they have now. The pilot showed them exactly what they need to fix.
