Can online assessments detect cheating?

Yes. While no method is 100% foolproof, many online assessment platforms use multiple security features to detect or deter cheating. Below are the primary ways they do it:

1. Proctoring Methods

1. Live Video Proctoring

   • A human proctor watches you via webcam in real time, noting suspicious movements or extra voices in the room.
   • Can require a 360° view of your environment before starting.

2. AI-Driven Monitoring

   • Artificial intelligence tracks head and eye movements, unusual background sounds, or additional faces.
   • Flags potential cheating for human review.

2. Lockdown Browser and System Checks

1. Browser Lockdown

   • Prevents opening new tabs, copying/pasting text, or accessing other programs.
   • Some also block screenshots or screen-sharing tools.

2. Tab-Switch Alerts

   • The platform may track each time you switch out of the test window.
   • Excessive switching can raise red flags, prompting a review.

3. Plagiarism Detection and Code Analysis

1. Automated Code Comparisons

   • Platforms like HackerRank or CodeSignal run similarity checks to spot copied code from other candidates or known repositories.
   • Checks structuring, variable naming, and logic patterns.

2. Statistical Analysis

   • Identical wrong answers, unusual speed, or matching “rare” solution methods can indicate collaboration or external help.

4. Identity Verification

1. Photo ID Checks
   • Test-takers may have to present a valid ID next to their face on camera to confirm identity.
2. Voice or Facial Recognition
   • In some cases, advanced biometric checks confirm that the same person remains at the computer throughout the test.

5. Question Variation and Randomization

1. Randomized Question Pools
   • Each candidate receives a different subset of questions or question order, discouraging answer sharing.
2. Adaptive or Personalized Tests
   • Adjusts difficulty and question flow based on performance, making it harder to rely on pre-prepared answer keys.

6. Practical Limitations

1. Secondary Devices or Offline Materials
   • Platforms can’t always detect if someone glances at hidden notes or a phone off-camera.
2. False Positives
   • AI-based systems might flag innocent behaviors (e.g., looking away to think) as potential cheating.
3. Legal and Privacy Concerns
   • Strict monitoring—like keylogging or recording entire screens—may conflict with local data protection laws, so not all companies use it.

Final Thoughts

Yes, online assessment platforms can detect cheating through webcam proctoring, AI monitoring, lockdown browsers, and plagiarism checks. Though not infallible, these methods significantly reduce the likelihood of dishonest behavior. For genuine test-takers, simply studying thoroughly and following exam guidelines is the safest path to success.
