As classrooms and workplaces increasingly shift toward digital tools, ensuring academic integrity and focused participation has become a growing challenge. Google Forms, one of the most widely used tools for quizzes, surveys, and assessments, offers a feature designed specifically to address this issue: Locked Mode. While many educators use Google Forms daily, fewer fully understand what Locked Mode does, how it works, and when it should be used.

TL;DR: Google Forms Locked Mode is a feature that prevents students from leaving a quiz once they begin, helping reduce cheating and distractions. It works exclusively on managed Chromebooks through Google Workspace for Education and restricts access to other browser tabs, apps, and screenshots during an assessment. Teachers can enable it when creating quizzes in Google Forms. While highly useful for controlled testing environments, it has device and administrative limitations.

What Is Google Forms Locked Mode?

Google Forms Locked Mode is a setting available in Google Workspace for Education that restricts students from navigating away from a quiz while it is in progress. Once enabled, students cannot open new tabs, access other applications, copy or paste information, or use browser shortcuts during the assessment.

This feature is specifically designed to maintain academic honesty in digital testing environments. When activated, it essentially locks students into the quiz interface until they submit their responses.

Unlike third-party proctoring software, Locked Mode does not record students through webcams or track eye movement. Instead, it provides a controlled browsing experience by limiting access to other resources during the quiz session.

How Does Locked Mode Work?

Locked Mode works within a specific ecosystem. It is not universally available to all Google users. To function properly, it requires:

  • A Google Workspace for Education account
  • A school-managed Chromebook
  • The quiz to be assigned through Google Forms

When a teacher enables Locked Mode in quiz settings, students who meet the device and account requirements will automatically enter a restricted testing environment upon starting the quiz.

Here’s what happens once Locked Mode is active:

  • Students cannot open other browser tabs.
  • Students cannot switch to other applications.
  • Copy and paste functions are disabled.
  • Printing is blocked.
  • Screenshots are disabled (on managed Chromebooks).
  • If a student exits the quiz, the teacher is notified.

This creates a digital testing experience similar to being monitored in a physical classroom.

How Teachers Enable Locked Mode

Setting up Locked Mode is relatively simple for educators who have the appropriate administrative permissions.

  1. Create a quiz in Google Forms.
  2. Click on Settings.
  3. Navigate to the Quizzes tab.
  4. Turn on “Make this a quiz.”
  5. Enable “Locked mode on Chromebooks.”

Once activated, the form must be assigned to students using their school-managed accounts. Teachers commonly distribute such quizzes through Google Classroom.

It’s important to note that Locked Mode cannot be retroactively applied once students have begun a quiz. Teachers must enable it beforehand.

Why Is Locked Mode Important?

Digital assessments come with both convenience and vulnerability. Without restrictions, students can easily:

  • Open additional tabs to search for answers
  • Communicate with others during the assessment
  • Access saved notes or digital textbooks
  • Copy and paste content from other sources

Locked Mode helps reduce these behaviors by narrowing the digital environment down to a single task.

Key benefits include:

  • Integrity: Encourages honest work during online tests.
  • Focus: Minimizes digital distractions.
  • Simplicity: Easy to enable without additional software.
  • Cost efficiency: No need for paid third-party proctoring services.

For schools increasingly conducting exams online, this feature bridges the gap between convenience and control.

Limitations of Google Forms Locked Mode

While Locked Mode is helpful, it is not a universal solution. It comes with important limitations that educators and administrators should understand.

1. Device Restriction

Locked Mode works only on school-managed Chromebooks. Students using:

  • Personal laptops
  • Windows devices
  • MacBooks
  • Tablets

— will not experience the locked environment.

2. Account Requirement

Students must be signed in using their school-issued Google account. Personal Gmail accounts do not support Locked Mode functionality.

3. Not Foolproof

While it blocks digital navigation on the device itself, Locked Mode cannot prevent:

  • Use of external devices (phones, tablets, smartwatches)
  • Looking at physical notes
  • Communication outside the Chromebook

For high-stakes examinations, additional monitoring measures may still be necessary.

Locked Mode vs. Third-Party Proctoring

Many institutions compare Google Forms Locked Mode with dedicated proctoring software. Each approach has distinct differences.

Locked Mode:

  • Free with Workspace for Education
  • No webcam monitoring
  • Basic restriction of browser activity
  • Simple setup

Third-party proctoring tools:

  • Often paid services
  • May include webcam recording
  • AI behavior monitoring
  • Identity verification features

Locked Mode is ideal for everyday quizzes and in-class assessments, while specialized proctoring software might be better suited for standardized or certification exams.

Best Practices for Using Locked Mode

To get the most out of Google Forms Locked Mode, educators should adopt strategic practices.

Prepare Students in Advance

Conduct a practice quiz so students understand how Locked Mode behaves. This prevents confusion or panic during real assessments.

Provide Clear Instructions

Explain that:

  • Exiting the quiz notifies the teacher.
  • Screenshots are disabled.
  • Other tabs cannot be accessed.

When expectations are clearly communicated, compliance improves.

Combine With Thoughtful Question Design

Locked Mode reduces browsing, but strong test design further discourages cheating. Consider:

  • Using open-ended questions
  • Shuffling answer options
  • Creating question banks
  • Limiting response windows

When combined, these methods create a much more secure digital assessment environment.

Common Questions About Locked Mode

Can students exit Locked Mode once they start?

Students can exit, but doing so will submit or pause the quiz depending on settings, and the teacher will be alerted.

Does Locked Mode monitor students through webcams?

No. It does not use cameras, microphones, or facial recognition.

Can Locked Mode be used outside of school?

It works anywhere as long as the student is using a school-managed Chromebook and signed into their managed account.

Is Locked Mode available for universities?

Yes, if the institution uses Google Workspace for Education and deploys managed Chromebooks.

The Future of Digital Testing and Locked Mode

As education continues moving toward hybrid and fully digital systems, tools like Google Forms Locked Mode will likely play an increasingly significant role. Schools need balanced solutions—technologies that maintain fairness without creating overwhelming surveillance environments.

Locked Mode represents a middle ground. It does not intrude on student privacy with video monitoring, yet it still enforces meaningful restrictions during assessments.

With continued advancements in cloud-based education, we may see expanded cross-device compatibility or deeper integration with administrative controls. For now, however, Locked Mode remains a practical, streamlined solution for Chromebook-based classrooms.

Final Thoughts

Google Forms Locked Mode is more than just a checkbox in quiz settings—it is a thoughtful response to modern digital learning challenges. By restricting navigation, disabling shortcuts, and keeping students focused within a quiz interface, it helps educators preserve academic integrity without complicated software installations.

Though it has device and ecosystem limitations, its simplicity and accessibility make it highly valuable in schools already operating within Google’s educational framework. For teachers seeking an easy way to create a more controlled testing environment, Locked Mode offers a reliable and user-friendly option.

As digital assessments become the norm rather than the exception, understanding tools like Locked Mode is essential. When used wisely and combined with strong instructional design, it can transform the online testing experience into something secure, efficient, and fair.
