Google Forms Locked Mode Explained: What It Does, Who Can Use It, and Its Limitations

Online quizzes are everywhere. Teachers use them. Schools depend on them. But one big question always pops up: How do you stop students from googling the answers? That’s where Google Forms Locked Mode comes in. It’s Google’s way of creating a safer testing space inside a digital world full of distractions.

TL;DR: Google Forms Locked Mode is a feature that prevents students from leaving a quiz while taking it. It only works on school-managed Chromebooks. Teachers can use it to reduce cheating and keep students focused. However, it has limits and does not completely prevent all forms of dishonesty.

What Is Google Forms Locked Mode?

Locked Mode is a special setting inside Google Forms. It is designed for quizzes. When turned on, it locks students into the quiz until they submit it.

That means students cannot:

• Open other browser tabs
• Switch to other apps
• Search Google for answers
• Copy and paste information

If they try to leave, the quiz is automatically submitted. Yes. Immediately.

It creates a controlled environment. Kind of like turning a Chromebook into a mini testing center.

Why Was Locked Mode Created?

Let’s be honest. Online testing can be messy.

Students have access to:

• Search engines
• Messaging apps
• AI tools
• Online notes
• Group chats

Without restrictions, it becomes very easy to cheat.

Google introduced Locked Mode to give teachers more control. The goal is simple:

Reduce distractions. Reduce cheating. Increase focus.

It is especially useful for:

• Midterms and finals
• Standardized practice tests
• Timed assessments
• In-class quizzes

Who Can Use Locked Mode?

Here’s where things get specific.

Locked Mode is not available to everyone.

It only works if:

• The school uses Google Workspace for Education
• The student is using a school-managed Chromebook
• The student is signed in with a school account

If a student is using:

• A personal laptop
• A MacBook
• A Windows PC
• An iPad
• A phone

Locked Mode will not work.

This is important. Very important.

Locked Mode depends on device control. Schools manage Chromebooks through the Google Admin console. That control allows Google to restrict system behavior during a quiz.

How Teachers Turn It On

The good news? It’s simple.

When creating a quiz in Google Forms:

1. Turn the form into a quiz under Settings.
2. Go to the Responses section.
3. Enable Locked Mode.

That’s it.

When students open the quiz on a managed Chromebook, the screen enters Locked Mode automatically.

What Happens During Locked Mode?

Here’s what students experience:

• The quiz opens full screen.
• They cannot open new tabs.
• They cannot minimize the window.
• Keyboard shortcuts are restricted.
• Right-click options may be disabled.

If they attempt to exit:

• The form is automatically submitted.
• The teacher can see that it was submitted early.

This creates accountability. Students know leaving ends the test. That alone reduces temptation.

What Locked Mode Does Well

Locked Mode shines in a few key areas.

1. Focus
Students stay on the test. No switching. No browsing.

2. Simplicity
There is no extra software to install.

3. Built-in to Google
It works seamlessly with Classroom and Forms.

4. Low stress for teachers
Setup takes seconds.

5. Cost effective
It is included in Google Workspace for Education.

For many classrooms, that’s enough.

But Here’s the Catch: The Limitations

Locked Mode is helpful. But it is not perfect.

1. Only Works on Managed Chromebooks

No Chromebook. No Locked Mode.

This limits flexibility. Schools that allow Bring Your Own Device (BYOD) cannot rely on it.

2. It Does Not Stop Physical Cheating

A student can still:

• Look at a notebook nearby
• Check a phone under the desk
• Whisper to a classmate
• Write answers on paper ahead of time

Locked Mode controls the screen. It does not control the room.

3. No Webcam Monitoring

Some testing platforms use cameras and AI monitoring. Google Forms does not.

Locked Mode does not:

• Record students
• Track eye movement
• Monitor surroundings

This is good for privacy. But it means less enforcement.

4. Limited Reporting

Teachers see when a quiz is submitted. But they do not get advanced cheating analytics.

No red flags. No suspicious behavior alerts.

5. Internet Required

Students need an internet connection. If Wi-Fi drops, things can get messy.

Is Locked Mode Cheating-Proof?

Short answer: No.

Long answer: It reduces opportunity, but it does not eliminate it.

Think of it like a seatbelt. It increases safety. But it does not guarantee perfection.

Students who are determined may still find ways around restrictions. Especially outside the device itself.

Locked Mode vs. Other Proctoring Tools

Some schools use dedicated proctoring software. These tools may include:

• Webcam monitoring
• Screen recording
• AI behavior tracking
• Browser lockdown across devices

Compared to those, Locked Mode is:

• Simpler
• Less invasive
• Easier to deploy
• Less powerful

It is designed for classrooms. Not for high-stakes national exams.

When Should Teachers Use Locked Mode?

It works best for:

• In-person classroom quizzes
• Short timed assessments
• Practice exams
• Situations where students use school Chromebooks

It may not be ideal for:

• Remote testing at home
• Mixed-device classrooms
• High-security certification exams

Teachers should think about context. What level of security is truly needed?

Tips for Using Locked Mode Effectively

Want better results? Try this:

• Combine Locked Mode with in-person supervision.
• Clearly explain rules before the test.
• Use question shuffling inside Google Forms.
• Limit response edits after submission.
• Set time limits for completion.

Layering strategies makes cheating harder.

Privacy and Student Trust

One of the biggest advantages of Locked Mode is privacy.

It does not:

• Spy on students
• Access personal files
• Track behavior outside the quiz

It simply locks the testing window.

This balance matters. Students feel less like they are under surveillance. Teachers maintain reasonable control.

The Big Picture

Education is changing fast.

AI tools exist. Search engines are powerful. Information is everywhere.

Locked Mode is one piece of the puzzle. It helps. But it is not the full solution.

Many educators are shifting toward:

• Open-book testing
• Project-based assessment
• Critical thinking questions
• Application-focused tasks

Why? Because memorization is no longer the only goal.

Sometimes the best defense against cheating is designing better questions.

Final Thoughts

Google Forms Locked Mode is a practical tool. It is easy to use. It increases focus. It reduces simple forms of cheating.

But it works only in specific conditions. It requires managed Chromebooks. And it does not monitor students beyond the screen.

Think of it as a classroom helper, not a digital police officer.

For many schools, that is more than enough.

The key is knowing what it can do. And what it cannot.

Use it wisely. Combine it with smart teaching strategies. And remember — the best assessments test thinking, not just searching.
