What is contract cheating, and can AI proctoring detect exam-sitting services?
TL;DR: Contract cheating means paying a third party — a person, essay mill, or exam-sitting service — to do coursework or take an exam in your place. AI proctoring fights the exam-sitting version through continuous identity verification: matching the test taker's face against their ID and selfie not just at check-in, but repeatedly through the session, so a stand-in fails a mid-exam re-check even if they passed the initial one.
Why a one-time ID check isn't enough
Older proctoring only verified identity at login — good enough to stop a stand-in from starting the exam, but useless if the actual candidate logs in, then hands off the keyboard to someone else once the check-in screen closes. Continuous verification closes that specific gap.
Contract cheating types vs detection method
| Type | Example | Detection method |
|---|---|---|
| Exam-sitting service | A third party logs in and takes the exam | Continuous face verification through the session |
| Essay mill | A third party writes an assignment | Plagiarism/AI-text detection, not proctoring's job |
| Friend takes the exam | Informal, unpaid stand-in | Same continuous ID verification catches both cases |
| Live coaching off-camera | Someone feeding answers during the exam | Audio analysis, second-voice detection, gaze tracking |
How to build defenses against it
- Require ID + selfie match at check-in, not as a one-time formality.
- Run periodic face re-verification throughout the session, not just at the start.
- Use audio analysis to catch a second voice or live coaching.
- Flag any moment the candidate's face isn't consistently visible or matching.
- Keep the full violation timeline and trust score as evidence for any misconduct case.
FAQ
Is contract cheating illegal? In many countries and institutions, running or advertising an exam-sitting/essay-mill service is illegal or a specific violation subject to disciplinary or legal action.
Can a stand-in pass a proctored exam? It's much harder with continuous re-verification, since a one-time check at login won't cover a handoff partway through.
Does AI proctoring stop essay mills too? Not directly — that's a plagiarism/AI-text detection problem for take-home work, separate from live exam proctoring.
