🔐 A Test Center Could Never Make Cheating This Difficult

For decades, test centers have been the go-to option for administering high-stakes English proficiency exams. But despite their reputation, traditional testing centers often fall short when it comes to real security. From inattentive proctors to tech loopholes, cheating in test centers is far more common—and easier—than most people realize.

That’s why the Duolingo English Test (DET) was built differently. From the ground up, DET integrates AI, multi-camera monitoring, and secure automation to eliminate the weaknesses of in-person testing environments. In this guide, we break down the limitations of test center security and how DET is setting a new standard for fairness and trust.

🎭 The Hidden Risks of Test Centers

While test centers may appear controlled and secure, the reality is often very different. Here are common vulnerabilities:

• Fake IDs used to impersonate other test takers
• Hidden notes under clothing or desks
• Smartwatches, invisible earpieces, or tech-enhanced glasses
• Leaked questions and answers passed between sessions
• Corrupt staff offering test assistance or altering results

Even with trained proctors, one person watching a room of 30+ test takers can’t catch everything. And in some documented cases, proctors themselves were the source of the misconduct.

🛡️ How the DET Closes Every Security Gap

Unlike test centers, DET is designed with digital-first precision and security. Here's how the system works to block cheating at every level:

🎥 1. Dual-Camera Monitoring

DET uses a two-camera system:

• Primary webcam: Captures your face and upper body.
• Smartphone camera: Gives a side view of your hands, screen, and surrounding space.

Together, they eliminate blind spots—making it impossible to hide notes, get help, or use devices without being detected.

🤖 2. AI-Powered Real-Time Analysis

During the test, AI monitors:

• Typing patterns to flag unnatural input or copy-pasting
• Screen activity to block unauthorized programs or tabs
• Sudden behavior shifts that may indicate cheating

The AI flags these events for human review after the test, creating a layered, unbiased evaluation process.

👀 3. Anonymous Human Proctor Review

Unlike test centers, where test takers can see and interact with proctors, DET proctors remain anonymous and only review sessions after the fact:

• Proctors cannot be bribed or influenced
• They follow strict protocols
• Reviews are triggered by AI flagging—not assumptions

This keeps everything consistent, impartial, and corruption-proof.
