Canvas can detect when you leave the test window, but what it records depends on your instructor's settings
Canvas (the learning platform used by most colleges and universities) has built-in tools that track when a student switches away from a test tab. Whether your instructor actually sees this information, and what they do with it, depends on how they configured the test when they created it. Canvas does not automatically flag or fail you for switching tabs — the instructor chooses whether to enable monitoring, what to monitor, and how to respond.
If your instructor enabled Respondus LockDown Browser or Proctorio (third-party proctoring tools that work with Canvas), those tools are much more aggressive. They lock your screen, prevent tab switching, and record video. But most Canvas tests do not use these tools. Most use Canvas's built-in monitoring, which is less restrictive and depends entirely on instructor choice.
Key Takeaways
- Canvas can log when you switch tabs or minimize the test window, but only if your instructor turned on that monitoring when building the test.
- Most instructors do not enable tab-switching detection, and even those who do usually do not penalize a single switch.
- Respondus LockDown Browser and Proctorio are different tools that actively prevent tab switching and record your screen — Canvas itself does not do this unless your instructor adds those tools.
- The safest approach is to assume your instructor can see tab switches and to avoid them during a test, regardless of whether monitoring is actually on.
How Canvas monitoring actually works
Canvas has a feature called Quiz Log that records timestamps for when a student opens the test, submits answers, and leaves the page. If your instructor enabled the setting called "Lock questions after answering," Canvas will also note if you try to go back and change an answer. But the basic Canvas system does not automatically detect tab switches — your instructor has to turn on a specific setting to log that behavior.
When an instructor creates a test in Canvas, they can choose to enable various quiz restrictions, but tab-switching detection is not a standard Canvas feature. What Canvas does track by default is the time you spend on the test and when you submit it. If you take an unusually long time or submit at an odd hour, that shows up in the log, but a tab switch does not unless the instructor has added extra monitoring. The confusion usually comes from the fact that Canvas shows instructors a lot of data about student behavior — time on page, number of attempts, IP address — and students assume all of it is being collected. In reality, instructors see only what they chose to enable when they built the test.
When Canvas does track tab switches
If your instructor is using Respondus LockDown Browser, tab switching is actively prevented, not just monitored. LockDown Browser locks your entire screen while you take the test. You cannot switch to another browser tab, open another program, or even see your desktop. If you try, the browser will not let you. The instructor sees an alert that you attempted to leave the test environment.
Proctorio works similarly but adds video recording and AI monitoring. It watches your face, your eye movements, and your screen. It flags suspicious behavior like looking away from the screen, multiple people in the room, or a second monitor. Proctorio is much more invasive than Canvas's built-in tools, and it is usually used for high-stakes exams like finals or placement tests. If your test does not mention LockDown Browser or Proctorio in the instructions, your instructor is probably using Canvas's basic monitoring or no monitoring at all. You can usually tell by looking at the test page itself — if it says "This test is proctored" or "You must use LockDown Browser," you will know before you start.
What happens if you switch tabs
If your instructor has enabled Canvas's basic tab-switch logging, switching tabs will be recorded in the Quiz Log. However, most instructors do not penalize a single tab switch. They use the log to catch patterns — a student who switches tabs 20 times, or who leaves the test window open while clearly doing something else, or who submits answers in a way that suggests they were copying from another source.
If you switch tabs once to check a spelling or look up a formula that was supposed to be provided in the test, most instructors will not care. If you switch tabs repeatedly or for long periods, or if you switch to a search engine or another student's screen, that is when instructors start to investigate. The log gives them evidence to support a conversation with you or a report to academic integrity. The safest approach is to treat every test as if monitoring is on, even if you think it is not. Assume your instructor can see tab switches. Do not switch tabs during the test. If you need to reference something, ask your instructor before the test whether you can use notes, a calculator, or the textbook. That way you have permission and do not have to guess whether a tab switch will be flagged.
How to check if your test has monitoring enabled
Before you start a test, look at the test instructions page. If monitoring is enabled, the instructions will usually say something like "This test is monitored" or "You must use LockDown Browser" or "Proctorio is required." If you do not see any warning, monitoring may still be on, but it is less likely to be the aggressive kind.
You can also ask your instructor directly. Send an email and ask: "Does this test use LockDown Browser or Proctorio? Can I use my notes or the textbook?" This is a normal question and instructors expect it. They will tell you what is allowed and what is monitored. That way you know exactly what to expect and can plan accordingly. If you are taking the test and you accidentally switch tabs, do not panic. One switch is not going to trigger an academic integrity investigation. Finish the test, submit it, and move on. If you are worried, you can email your instructor after and mention that you accidentally switched tabs and ask if that is a problem. Most instructors will tell you it is fine.
The difference between Canvas monitoring and third-party proctoring
| Feature | Canvas Built-In | LockDown Browser | Proctorio |
|---|---|---|---|
| Prevents tab switching | No | Yes | Yes |
| Records video | No | No | Yes |
| Monitors eye movement | No | No | Yes |
| Logs time spent on test | Yes | Yes | Yes |
| Requires read | No | Yes | Yes |
| Instructor sees tab switches | Only if enabled | Yes, if attempted | Yes, if attempted |
Canvas's built-in tools are the least invasive. They log behavior but do not prevent it. LockDown Browser and Proctorio are much stricter. They physically prevent you from leaving the test window and record evidence if you try. If your instructor is using one of these tools, you will know it before the test starts because you will have to read the software and install it on your computer.
The key difference is that Canvas gives your instructor visibility into what happened, but does not stop you from doing it. LockDown Browser and Proctorio stop you from doing it in the first place. This means that with Canvas alone, you could theoretically switch tabs and your instructor might not care. With LockDown Browser or Proctorio, you cannot switch tabs at all, so the question becomes moot.
What to do if you are worried about monitoring
If you are concerned that monitoring is on and you are not sure what is allowed, the best move is to ask your instructor before the test. Tell them you want to make sure you follow the rules and ask what you can and cannot do. Can you use your textbook? Can you have notes? Can you look something up if you get stuck? Most instructors will give you clear answers.
If you are taking the test and you realize you need to switch tabs to look something up, stop and think about whether you have permission. If you do not, do not switch. If you do, go ahead. If you are not sure, finish the test without switching and then email your instructor to ask if that would have been allowed. It is better to ask after than to risk a flag during. If you have already switched tabs during a test and you are worried about it, you can email your instructor and explain what happened. Say something like: "I accidentally switched tabs during the test to check [whatever]. I know that might be monitored. I wanted to let you know in case you see it in the log." Most instructors will appreciate the honesty and will not penalize you for an accidental switch.
Frequently Asked Questions
Can Canvas see my screen if I minimize the test window?
Canvas can log that you minimized the window if your instructor enabled that monitoring, but Canvas cannot see what is on your screen when you minimize it. LockDown Browser and Proctorio can see your entire screen and will flag a minimize as a violation. With Canvas alone, minimizing is logged but usually not penalized unless it happens repeatedly.
Does Canvas know if I open a second monitor?
Canvas itself cannot detect a second monitor. Proctorio can, because it records your screen and can see if you are looking at something off to the side. LockDown Browser cannot detect a second monitor either, but it will prevent you from switching to it. If you are using Canvas's basic monitoring, a second monitor is not detected unless your instructor is watching you in real time through a live proctoring session.
What if I switch tabs to check my email by accident?
If you switch tabs once by accident, most instructors will not care. Canvas logs it, but one switch is not suspicious. If you switch multiple times or stay on another tab for a long time, that is when it looks intentional. If you are worried, you can email your instructor after the test and explain it was accidental.
Can my instructor tell if I copied answers from another student?
Canvas cannot automatically detect copying. However, if two students submit nearly identical answers, or if answers are submitted in an unusual order, or if a student's answers suddenly improve dramatically, instructors will investigate. They may ask you to retake the test, or they may report it to academic integrity. The Canvas log can show whether you were looking at the test for a reasonable amount of time or whether you submitted answers too quickly.
Do I need to close other browser tabs before starting a Canvas test?
You do not have to close other tabs if you are using Canvas's basic monitoring. However, it is a good idea to close them anyway so you are not tempted to switch. If you are using LockDown Browser or Proctorio, those tools will close other tabs for you or prevent you from accessing them. The safest approach is to close everything except Canvas before you start.
