Canvas Quiz Logs Explained: What Professors Can Actually See

The short answer: yes, your professor can open the Canvas quiz log for any attempt, and yes, it shows when you switched tabs. No, it does not show keystrokes, browser history, or what you were doing in another window. The log is a list of timestamped events about what happened inside the Canvas quiz page itself.

Below is the full breakdown so you do not have to guess what is in there.

What the Canvas quiz log actually is

Canvas records a per-attempt event log for every quiz a student takes. Instructors open it from SpeedGrader by clicking the attempt and selecting "View Log." The log was added so professors can investigate suspicious attempts. Most professors never look at it. Some look at every attempt. You usually find out which kind of professor yours is only after you are accused of something.

The log is built from events the Canvas quiz page can observe. That is a smaller set than people assume.

Every event the Canvas quiz log records

For one quiz attempt, the log can show:

• Question viewed. The question now showing on screen plus the timestamp.
• Answered. When you typed or selected an answer, and what the answer was.
• Answer changed. Each time you change an answer, the previous and new value are both saved.
• Question unanswered. When you cleared an answer.
• Stopped viewing the Canvas exam page. When the Canvas tab loses focus. This includes switching tabs, opening a new window, clicking on a different application, or letting the screen sleep.
• Resumed viewing the Canvas exam page. When focus returned.
• Submitted. Final submission with timestamp.

Each of these events has a timestamp accurate to the second.

What the Canvas quiz log does not record

This is the part most Reddit threads get wrong:

• It does not record keystrokes outside the Canvas page.
• It does not record clipboard activity. Canvas cannot tell when you copy or paste.
• It does not record mouse movement.
• It does not log what you opened in another tab. It only knows that focus left the page.
• It does not record extension activity that happens inside the page itself. If a Chrome extension fills a form field, Canvas sees the field change, just like it would for a typing student.
• It does not have access to your operating system, your camera, your microphone, or your other apps. That is what proctoring tools (Respondus, Honorlock, Proctorio) do, and they are separate from Canvas.

How long is "stopped viewing" before it gets flagged

There is no fixed threshold. The log records every focus loss with the exact duration. A 2 second focus loss is in the log just like a 5 minute one is. What matters is how a human reading the log interprets it.

A few harmless cases that still create entries:

• Clicking on a non Canvas browser tab to check the time.
• Opening a popup blocker prompt.
• Right clicking inside the page in some browsers.
• Switching to your password manager.
• Scrolling on a touch device that fires a focus shift.

A 4 minute gap in the middle of question 7 looks very different from a 3 second gap when you tabbed to your music player. Professors know this. The log itself does not.

What professors actually look for when they open the log

Three patterns get attention:

1. Long stopped viewing gaps inside a question. Especially if the answer is suddenly correct after a 3 minute gap.
2. Suspicious answer change patterns. Answer A, see question 8, come back, change to C. That suggests external lookup.
3. Impossible speed. Submitting 30 questions in 90 seconds when the quiz is supposed to take 30 minutes.

A clean log looks like a steady rhythm of view, answer, view, answer, submit. That is what an honest student attempt also looks like.

Common myths about the Canvas quiz log

Myth: The log proves cheating. Reality: The log shows behavior that may be consistent with cheating. It is evidence, not proof. Many false positives exist (focus loss from notifications, browser glitches, accidental key presses). A professor who treats the log as proof is misusing it.

Myth: Canvas knows which tab I switched to. Reality: It does not. It only knows you left the page.

Myth: The log records what I typed in ChatGPT. Reality: Canvas has no visibility outside its own page. It cannot see your other tabs or your applications.

Myth: If I never tab switched, the log will be empty. Reality: The log will still have view, answer, and submission events. "Empty" is not the goal. A clean rhythm is.

Myth: Refreshing the page hides the log. Reality: Refreshing creates its own events and does not erase prior ones. Avoid it during a quiz.

Myth: Students can see their own quiz log. Reality: No. Only instructors can. The closest you can do is take a practice quiz and ask a TA to show you the log afterward.

What if my log already has a stopped viewing event I cannot explain

It happens. Common harmless reasons:

• A system notification took focus.
• Your laptop briefly slept and woke up.
• A browser extension prompt appeared.
• You moved between two monitors.
• You accidentally pressed Cmd or Ctrl combined with a tab key.

If a professor questions a flag, calmly explain what you remember. If your school requires it, request a meeting before any decision is made. Keep your tone respectful and ask what other evidence supports their concern. The log alone is rarely enough to act on without other context.

Things you can do to keep your log clean

You do not need any tools for this. A few habits help:

• Close other tabs before you start the quiz.
• Turn off notifications and Do Not Disturb mode.
• Plug in your laptop so it does not sleep.
• Disable your password manager popup if it auto fires.
• Avoid right clicking inside the quiz.
• Avoid Cmd Tab or Alt Tab during the attempt.

FAQ

Can my professor see my log in real time during the exam? No. The log updates as you take the quiz, but professors typically open it only after the attempt is submitted.

Does the log get deleted after the semester ends? The log persists as long as the course exists. Schools have their own retention policies, but you should assume the log stays accessible.

Will using a Chrome extension show in the log? If the extension operates inside the Canvas page (modifying form fields, clicking radios), the log shows the field changes but not the extension itself. If the extension opens a new tab or window, that focus loss is logged. See our post on Chrome extensions and the Canvas quiz log for the long version.

What if I lost internet during the quiz? The log records the events that did make it to Canvas. Submissions or answer changes that did not transmit may not appear. Email your professor right away with the timestamp and a screenshot of any error you saw.

Does the log work on Canvas mobile? Yes. The same events fire from the mobile web. The native Canvas iOS and Android apps record similar engagement events, though the granularity is slightly different.

Can the log distinguish between two devices logged into the same account? No. The log only sees the page that submitted the events.
