Each test attempt has a maximum number of evidence files it can store. If some violations in a proctoring report are missing their evidence, the total number of violations exceeded this storage limit.

​
Understanding Violations vs. Evidence

Violation

An event that AutoProctor detects as anomalous. For example, no face detected on the camera feed, or the candidate switching to a different tab.

Evidence

Supporting documentation of the violation. For example, a photo of the camera feed when no face was detected, or a screenshot of the tab the candidate visited.
The Trust Score is calculated based on the type, frequency, and duration of violations. Evidence files are provided in the proctoring report so you can review what happened during the test.

​
Three Reasons for Missing Evidence

​
1. Storage Limit Reached (Most Common)

When a test starts, AutoProctor allocates a fixed number of storage URLs for evidence files. Once this capacity is reached, the system randomly decides whether to overwrite existing evidence or skip storing new evidence (50% probability each).
The Trust Score depends on violations, not on whether evidence is stored. All violations are tracked and affect the Trust Score even when evidence files are not available for viewing.

​
2. Device or Internet Issues

The candidate’s device or internet connection may have prevented the screenshot from being captured or transmitted to AutoProctor’s servers. This is common when candidates experience brief connectivity drops during the test.

​
3. Test Proctoring Settings

The test administrator may have disabled evidence storage through the test’s proctoring configuration. Check your proctoring settings to confirm that evidence recording is enabled.
