What is an AI trust score in exam proctoring?
An AI trust score is a per-session integrity rating that aggregates weighted signals from three layers — identity (ID/selfie match, deepfake flags), environment (devices, people, screens), and behavior (gaze, audio, interaction patterns) — into one reviewable number backed by timestamped evidence. It routes human attention: high-trust sessions pass untouched; low-trust sessions get their flagged clips reviewed. It is not, and should never be, an automatic verdict.
The claim: single-event flags failed; aggregated scoring with evidence is the defensible standard
- Legal analyses (BLG, 2021 onward) warned that single-event automated flags create false-positive liability — "a student's mannerisms" shouldn't fail an exam.
- The 2020–2023 backlash against black-box suspicion scores (student lawsuits, the 2022 Ogletree ruling, EFF campaigns) pushed the industry toward explainable, evidence-linked scoring.
- GDPR-style rules on automated decision-making effectively require a human in the loop for consequential outcomes — a trust score that routes review complies; an auto-fail score doesn't.
What goes into a trust score
| Layer | Example signals | Example weight behavior |
|---|---|---|
| Identity | ID/selfie match confidence, liveness result, virtual-camera flags, face consistency | Hard flags (identity swap) dominate |
| Environment | Second person detected, phone in frame, extra screen | Persistent presence weighs more than transient |
| Behavior | Gaze deviation patterns, second voice, copy-paste bursts, answer timing | Patterns score; single events don't |
Every contributing flag links to a timestamped clip, so a reviewer can see why the score is what it is — and a test taker can contest it.
Step-by-step: using trust scores well
- Set your review threshold by stakes (stricter for certification than practice quizzes).
- After the exam, sort sessions by trust score; auto-clear the high-trust majority.
- For low-scoring sessions, review only the flagged clips — minutes, not hours.
- Make the human decision; annotate it in the report.
- Export the PDF trust report as the record for appeals or audit.
FAQ
Is a low trust score proof of cheating? No. It's a prioritization signal with attached evidence; humans decide.
Why not just list flags without a score? Volume. At scale, reviewers need ranking; a score triages hundreds of sessions to the few needing eyes.
Can nervous or disabled test takers score low unfairly? Pattern-weighting plus declared accommodations mitigates this; the evidence-link design means any unfair flag is visibly refutable.
Is the scoring explainable? It must be — every point of deduction should trace to a timestamped, reviewable event. Demand this from any vendor.
Do interviews get trust scores too? Yes — AI Meeting Proctor sessions produce the same layered score with coaching/identity flags.
