How the Duolingo English Test Ensures Secure Proctoring

How does Duolingo ensure security and prevent cheating? 🔒 The DET is a go-to option for proving English proficiency and since it’s taken entirely online, many test-takers have that very question!

Let’s break down the DET’s multi-tiered proctoring system, which blends human oversight and AI technology to maintain fairness and integrity.

What is Proctoring?

Proctoring is monitoring an exam to ensure rules are followed. Traditionally, this meant an in-person instructor overseeing students. But with online exams like the DET, a more advanced approach is needed.

How the DET Uses Digital Proctoring

Since the DET is fully digital, Duolingo created a multi-layered security system combining human reviewers and AI detection.

1. Test Recording 🎥

• Every test session is fully recorded on video, including screen activity.
• Multiple human proctors review each session within 48 hours to verify compliance.

2. Three Levels of Proctors 🕵️‍♂️

Duolingo’s three-tiered proctoring system ensures fairness:

• First-Tier Proctors – Verify IDs and look for any suspicious behaviors.
• Second-Tier Proctors – ESL experts analyze writing and speaking responses for authenticity.
• Third-Tier Proctors – Senior reviewers handle complex cases and ensure accuracy.

3. Human Review Supported by AI 🤖

• AI flags potential issues, like ID mismatches or unusual behavior.
• However, humans always make the final decision—AI is just an assistant.

Why This Proctoring System Works ✅

The DET’s approach is more secure than traditional testing methods:

• Higher Security – Multiple proctors review each test, reducing errors.
• Global Accessibility – Take the test anywhere, anytime, without compromising security.
• Anonymity – Proctors are anonymous to prevent bias.
• Recorded Evidence – If there’s any dispute, test sessions can be reviewed.

Why This Matters for Test-Takers 🎓

Every DET session is unique with varying questions, ensuring a fair experience. No two exams are the same, eliminating test-sharing concerns.

The Duolingo English Test proves that online testing can be both flexible and secure. Its combination of AI monitoring and human oversight ensures fairness and peace of mind for test-takers.
