Can Moodle Detect Switching Tabs? Logs, SEB, and What Teachers See

Updated July 2026

The tab question, answered precisely

“Can Moodle detect switching tabs” is really three different questions, and they have three different answers:

• Can it see what’s in your other tabs? No — browsers don’t allow any website to read other tabs. Not Moodle, not anything.
• Can it know you LEFT the quiz tab? Sometimes. A browser page can tell when it loses focus, and some Moodle configurations and proctoring plugins record those focus-loss events with timestamps. Plain, unmodified Moodle quizzes generally don’t — but you can’t tell from your seat which setup you’re in.
• Can it stop you from switching at all? Yes, when the quiz requires Safe Exam Browser — Moodle’s supported lockdown tool, which locks the machine to the exam until it’s submitted.

So the honest operating assumption: leaving the quiz page may be recorded, and on an SEB exam it’s simply impossible. The gray zone in between is not knowable from the student side.

What Moodle’s logs actually show teachers

Moodle is famously log-heavy — close to every click in a course is recorded. For a quiz, an instructor can typically see:

None of this is tab detection — it’s timing forensics. A student who vanishes for four minutes mid-quiz and returns to nail three hard questions has told the log a story, no proctoring required. It’s the same quiz-log dynamic as Canvas, with Moodle logging even more of it.

The add-on layers: SEB, proctoring plugins, and plagiarism scanners

Because Moodle is open-source, institutions customize it heavily, and the detection posture varies more than on any other LMS:

• Safe Exam Browser — the lockdown standard. Blocks tabs, apps, and copy-paste outright. If your exam page tells you to download SEB, that exam is locked.
• Proctoring plugins — webcam snapshots, screen recording, identity checks, and focus-loss tracking exist as installable plugins. They announce themselves (camera permission prompts, consent screens) — proctoring is never invisible.
• Plagiarism and AI plugins — Turnitin and similar services integrate into Moodle assignments. Where installed, essay submissions get similarity and AI-writing scores; where not, no scan happens. Moodle ships neither natively.

If you’re unsure what your course runs, the exam instructions and the assignment’s submission screen tell you most of it — required software, camera prompts, or a Turnitin agreement are all explicit.

How to tell what YOUR exam is running

Moodle setups differ so much that the only reliable answer comes from the exam itself. Four honest tells, all visible before you start:

• An SEB download link or “requires Safe Exam Browser” note on the quiz page → the exam is locked; other tabs are impossible, not just risky.
• A camera or microphone permission prompt → a proctoring plugin is active and recording is part of the deal. Proctoring always announces itself; it can’t run without permissions.
• A Turnitin (or similar) agreement on the submission screen → essays on this assignment get similarity and possibly AI scores.
• A plain quiz page with none of the above → you’re on standard Moodle: interaction logs and timing only. That’s not an invitation — the timing forensics above still apply — but it defines what exists.

When it matters and the page doesn’t say, asking the instructor what monitoring the exam uses is a legitimate question — schools are generally required to be transparent about recording.

What Moodle genuinely cannot do

For completeness, the boundary on the other side — none of these are possible for Moodle or any website, on any setup:

• Read the contents of other tabs, apps, or your clipboard.
• See your screen, camera, or microphone without an explicit permission prompt.
• Watch your phone or a second device sitting next to your keyboard — which is exactly why high-stakes exams add webcam proctoring or in-person invigilation rather than trusting any browser-side control.
• Retroactively discover what you did during a logged gap. The log shows silence; it can never show what filled it.

Schools know these limits, which is why the serious detection on Moodle has always lived in the add-on layers — and why a plain unproctored quiz relies, in the end, on the same thing take-home work always has: whether the submitted answers plausibly belong to you.

Frequently asked questions

Can Moodle see what’s in your other tabs?

No. No website can read the contents of other tabs — that’s a browser security boundary. The most any Moodle setup can know is whether the quiz window lost focus, and only when the site or a plugin is configured to track it.

Can teachers see how long you spent on each quiz question?

Often, yes. Moodle’s quiz reports and logs show when the attempt started, when answers were saved, and when it was submitted — which reveals per-question pacing and long gaps with no interaction.

Does Moodle have AI detection?

Not natively. Moodle can integrate plagiarism and AI-detection services (including Turnitin) as plugins, so whether your work is scanned depends entirely on what your institution installed and enabled on that assignment.

What is Safe Exam Browser on Moodle?

Safe Exam Browser (SEB) is Moodle’s supported lockdown option: a special browser that locks your computer to the exam — no tabs, no apps, no copy-paste — until you’re done. If a quiz requires SEB, tab-switching isn’t detected; it’s impossible.

Can Moodle detect cheating on regular (non-quiz) assignments?

Only through what’s attached: a plagiarism/AI plugin if installed, submission timestamps, and the teacher’s read on your work. Uploaded-file assignments carry no activity monitoring at all.
