How much internet bandwidth does AI proctoring need to work reliably?
TL;DR: Most browser-based AI proctoring — streaming or recording webcam, screen, and audio — runs comfortably on roughly 1-2 Mbps upload. Below about 0.5 Mbps, expect dropped video frames, audio stutter, or paused sessions. Because AI proctoring processes signals in the background rather than requiring a human to watch a live feed continuously, it tolerates variable connections better than live human-monitored proctoring does.
Why upload speed matters more than download
The test taker's device is constantly sending webcam video, screen capture, and audio to the proctoring system — that's an upload-heavy load, not a download-heavy one. A connection that streams video fine (good download) can still choke on a proctored exam if upload speed is poor, which is common on many home and mobile networks.
Connection speed vs experience
| Upload speed | Expected experience |
|---|---|
| 2+ Mbps | Smooth video/audio, no interruptions |
| 1-2 Mbps | Generally reliable, occasional minor lag |
| 0.5-1 Mbps | Noticeable lag, possible frame drops |
| Below 0.5 Mbps | Frequent disconnects, session may pause or fail |
What to do about a weak connection
- Run a bandwidth test (upload specifically) on the exam device before the actual test day.
- Move closer to the router or use a wired connection instead of Wi-Fi if possible.
- Close other bandwidth-heavy apps (streaming, video calls, large downloads) during the exam.
- Ask the exam provider about a low-bandwidth or offline-first mode if your connection is marginal.
- Have a documented fallback (test center, rescheduled slot) for candidates in areas with genuinely unreliable internet.
FAQ
What happens if my connection drops mid-exam? Most systems pause and flag the interruption for review rather than auto-failing the candidate — check your specific provider's policy in advance.
Does a slow connection get you flagged as suspicious? No — connection issues are typically treated as a technical event, separate from a behavior or integrity flag.
Is mobile data reliable enough for a proctored exam? It can work, but Wi-Fi or a wired connection is more stable for a long, high-stakes exam session.
