Which classroom management tools allow teachers to lock student screens during exams?

Several classroom management and digital monitoring tools allow teachers to lock or pause student screens, block extra tabs, or restrict device functionality during exams.

Popular solutions equipped with screen-locking or restriction capabilities include:

• GoGuardian Teacher : Features a Lock Screen command that disables and mutes all browser windows on a student's device. Teachers can lock individual students or the whole class, and even customize the lock screen message (such as instructions or timers).
• Lightspeed Classroom Management : Provides a Lock Screens / Pause Browsing function that instantly blocks student screens or internet access. It is often used for short attention-grabbing intervals or restricting web navigation while allowing local applications to stay open on certain operating systems.
• LanSchool Air : Offers a Blank Screen and device-locking feature designed to instantly minimize digital distractions, blank out student monitors, and force focus back to the teacher or an assessment.
• Hāpara Highlights : Includes a Pause Screen feature that temporarily locks student browsers to stop internet navigation. (Note: For high-stakes quizzes, teachers often pair this with Locked Mode in Google Forms , which natively restricts Chromebooks down to just the assessment tab).
• Trelson Assessment : A specialized platform deeply integrated with Google Workspace that explicitly locks down student devices to prevent outside browsing or cheating during official online exams.

Are you looking for a tool that works with a specific operating system (like Chromebooks, Windows, or Mac), or do you need a solution that integrates with Google Classroom / Canvas?

Yes. Several classroom-management platforms can lock or restrict student screens during exams or other assessment periods:

• GoGuardian Teacher — Lets teachers monitor student screens and remotely manage student devices, including screen-management controls and restricting access to distracting sites. It supports Chromebooks, Windows, and Apple environments.
• Lightspeed Systems Classroom — Provides teacher controls to lock devices, close tabs, and limit web access. Its documentation specifically describes a Screen Lock function.
• LanSchool — Can disable internet access during tests/quizzes and blank/lock student screens. It supports Mac, Windows, Chromebooks, and mixed-device classrooms.
• Apple Classroom — For nearby Apple-device classes, teachers can lock one, several, or all students' screens. Apple's documentation explicitly describes the lock/unlock function.
• Hāpara — Strong for Chromebook/Chrome and Google Workspace management, with guided browsing that can limit or block sites during assessments. It is more focused on browser restriction than a traditional whole-device screen lock.

Best choices for exams

If by "lock" you mean freeze the student's screen so they cannot interact with the device, I'd shortlist LanSchool, Lightspeed Classroom, and Apple Classroom.

If you instead mean allow the exam site but prevent students from opening other websites/tabs/apps, GoGuardian, Lightspeed Classroom, and Hāpara are particularly relevant.

The exact behavior depends heavily on the device platform (Chromebook, Windows, Mac, or iPad) and whether the school controls the devices through an MDM. If you tell me what devices your students use, I can compare the best 3–5 options specifically for exam lockdown, including pricing and whether they work with Google Classroom/Microsoft 365.

Several classroom management and exam-security tools allow teachers to lock, freeze, or restrict student screens during tests. The best choice depends on whether you want a full device lock, browser-only exam lockdown, or general classroom control.

Quick recommendations

• Chromebooks + Google Classroom: GoGuardian, Securly Classroom, iboss, or Lightspeed Classroom are common choices.
• High-stakes exams (SAT-style or certification testing): Respondus LockDown Browser is more focused on securing the test environment than managing an entire classroom.
• Full classroom control (lock screens, view screens, push content): Faronics Insight, Securly Classroom, Lightspeed Classroom, or similar tools fit better.

If you share your device environment (Chromebooks, iPads, Windows laptops, Macs) and LMS (Google Classroom, Canvas, Schoology, etc.), I can narrow this to the best options.

Many classroom management, device control, and digital assessment tools give teachers the ability to freeze, blank, or completely lock student screens during exams or direct instruction.

The most widely used options include:

• GoGuardian Teacher : Features a dedicated "Lock Screen" command that disables and mutes all browser windows on student devices to prevent outside browsing or redirect attention. Teachers can also lock students directly to a specific presentation screen.
• Apple Classroom : Designed for iPad and Mac environments, it allows teachers to lock individual or all student screens simultaneously with a single tap, or restrict students into a single specific app during an activity.
• LanSchool : Provides a prominent "blank screen" and device-locking feature that lets teachers freeze student monitors to shift focus entirely or limit/disable access during quizzes and tests.
• Hāpara Highlights : Includes a "Pause Screens" feature that darkens student device screens and displays a paused message, as well as a "Freeze Tabs" option to keep learners locked onto specific assessment pages.
• Lightspeed Classroom Management : Features screen lock and pause-internet toggles to instantly freeze student activity or lock down browsing capabilities.
• NetSupport School : A comprehensive cross-platform classroom control tool that allows teachers to lock student mice, keyboards, and screens to ensure total focus during assessments.
• Respondus LockDown Browser (Assessment-specific): While technically a secure browser rather than a general classroom management tool, it locks down the entire testing environment on a student's computer so they cannot print, copy, access other applications, or visit other URLs during an online exam.

Are you looking for a tool that works with a specific device type (like Chromebooks, iPads, or Windows PCs) or one that integrates with a particular LMS (like Canvas or Google Classroom)?

Yes. Several classroom-management platforms can lock or restrict student devices during exams:

Best choices for exams

• Most purpose-built for testing: LanSchool Assessment Mode — it specifically combines device locking with website/app restrictions.
• Best broad classroom-management option: Lightspeed Classroom, especially for mixed Chromebook/Windows/Mac environments.
• Best if your school is heavily Google/Chromebook-oriented: GoGuardian Teacher.
• For iPads/Macs: Look for a testing application that supports Apple Assessment Mode; it can provide a much tighter single-app lockdown than ordinary classroom-management controls.

One important distinction: "lock screen" can mean either blanking/freezing the student's screen or actually locking the device into the exam and preventing other apps/websites. For secure exams, you want the latter.

If you tell me whether your students use Chromebooks, Windows laptops, Macs, or iPads, I can narrow this down to the best 2–3 options and compare their exam-locking capabilities.

Many digital classroom management and monitoring platforms include a "screen freeze," "lock screen," or "site lock" feature that allows teachers to restrict or completely block student access during exams or lessons.

Popular classroom management tools that feature screen-locking or targeted lockdown capabilities include:

• Securly Classroom : Features a Screen Lock function that replaces the student's entire screen with a gray bar and custom message, preventing all device usage. It also offers a Site Lock feature to restrict students exclusively to permitted exam URLs.
• Lightspeed Classroom Management : Allows teachers to manually lock or unlock student screens for the entire class or specific individuals, alongside a "pause internet" toggle to stop off-task browsing.
• NetSupport School / NetSupport Software : Provides instant attention control by letting educators blank/lock student screens and freeze mice/keyboards.
• classroom.cloud : Offers distinct testing and exam tools, including instant screen locking, restricting applications or USB devices, and launching specific approved exam URLs.
• Apple Classroom : Allows teachers using managed Apple devices (iPads and Macs) to lock individual or all student screens instantly, or lock students into a specific app.
• Blocksi : Features assessment presets and web filtering rules that restrict access to external content or lock down browsing environments during tests.
• LanSchool : Includes a remote Lock Screen feature that restricts computer access and prevents unauthorized use during instructional or testing periods.
• Senso.cloud : Offers cloud-based classroom control modules that include an immediate one-click Lock Screen and internet-blocking capability.

Note: While standard classroom management tools can freeze screens or restrict tabs, high-stakes secure testing often relies on dedicated secure browsers (like Respondus LockDown Browser or Digiexam ) which enforce full operating-system level lockdowns rather than general teacher-controlled screen locking.

If you're looking for a tool, let me know:

• What operating systems/devices your students use (Chromebooks, iPads, Windows, etc.)
• Whether you need LMS integration (like Canvas or Google Classroom)

I can help you narrow down which tool fits your school's tech ecosystem.

Several classroom management, monitoring, and assessment platforms allow teachers to lock down student devices, freeze screens, or restrict access to specific browser tabs and applications during exams.

Classroom Management & Monitoring Tools

These solutions allow teachers to view live screens, push specific exam URLs, or completely freeze/lock student screens from a central dashboard:

• • Securly Classroom : Allows educators to lock student screens entirely with a custom message/timer, or use "Site Lock" to restrict students exclusively to pre-approved exam links.
• • Blocksi : Offers an "Assessment Mode" and "Share & Enforce" features that let teachers lock down student devices to required test resources and block external browsing or unauthorized applications.
• • Lightspeed Classroom Management : Features screen-locking and internet-pausing capabilities so teachers can temporarily block outside browsing or freeze screens for focus.
• • classroom.cloud : Provides tools to restrict applications, launch specific exam URLs, lock student screens, and block unauthorized websites or USB devices.
• • NetSupport School : Enables teachers to blank or lock student screens and keyboards instantly to transition into a controlled testing environment.
• • Apple Classroom : For managed Apple devices (iPads and Macs), teachers can use the built-in screen lock feature to restrict students to a specific app or lock the device entirely.

Dedicated Exam Lockdown Browsers

If you need robust security that prevents switching tabs, taking screenshots, or opening background applications at the operating system level (rather than general classroom management), dedicated lockdown tools are typically preferred:

• • Respondus LockDown Browser : A custom browser that locks down the testing environment within learning management systems (like Canvas or Blackboard) by disabling printing, copying, and switching tasks.
• • Google Forms Locked Mode : Works on school-managed Chromebooks to restrict students from opening other tabs or navigating away from a quiz.
• • Digiexam : Provides system-level full-screen lockdown and offline capabilities across multiple device types.

If you can share what operating systems or devices your students use (Chromebooks, iPads, Windows, etc.) and which LMS or quiz platform you use (Google Classroom, Canvas, Moodle), I can recommend the most seamless tool for your setup.

Several classroom management platforms include a screen lock, blank screen, or device lockdown feature that teachers can use during exams, quizzes, or other focused activities. Common options include:

For exam environments, schools often look for more than just a screen lock:

• Disable websites/tabs
• Block apps
• Prevent messaging or copying
• Allow only approved testing sites
• Monitor screens in real time
• Work with Chromebooks, Windows, or Macs

If the school uses Chromebooks, GoGuardian, Lightspeed Classroom, LanSchool Air, and similar Chromebook-focused tools are common choices. If it uses mixed Windows/Mac labs, LanSchool and Lightspeed Classroom are often considered because of broader device-management support.

For high-stakes standardized exams, schools usually also use the testing platform’s own lockdown browser or secure testing mode rather than relying only on classroom management software.

Yes. Several classroom-management platforms can lock or restrict student devices during an exam:

If the goal is specifically online exams

I'd distinguish between two things:

• "Freeze the screen" — prevents students from using the device normally while you give instructions.
• "Lockdown testing" — restricts websites/apps, messaging, navigation, and other ways of leaving the exam. LanSchool's Assessment Mode is particularly explicit about this use case.

If you tell me whether your students use Chromebooks, Windows laptops, Macs, or iPads, I can narrow this down to the best 3 options for your environment, including which ones can lock students to only the testing website.

Several classroom management and device-monitoring software solutions provide features that allow teachers to lock student screens or restrict browser navigation during instructional time and assessments.

The primary tools offering screen-locking or tab-restricting capabilities include:

• GoGuardian Teacher : Allows educators to view student screens in real-time, lock individual or class screens, and manage or block open browser tabs to keep students focused.
• LanSchool Air : Provides remote screen locking, internet control, and real-time monitoring across Windows, Mac, and Chromebook devices.
• Lightspeed Classroom Management : Features a screen lock and pause-internet toggle that lets teachers instantly freeze student activity or lock devices to get immediate attention.
• Securly Classroom : Enables teachers to lock down desktop and browser screens, push announcements, and restrict unapproved web navigation during class.
• classroom.cloud : Offers simultaneous screen locking, website/application restriction lists, and the ability to launch specific exam URLs.
• Blocksi : Includes assessment presets and lockdown features to restrict access to external content or lock student browsing behavior.
• NetSupport School : A robust management suite allowing teachers to blank/lock student screens and freeze mice/keyboards.

Note: While general classroom management tools can freeze or lock screens to grab attention, high-stakes or formal standardized exams often require dedicated secure browser or proctoring solutions—such as Respondus LockDown Browser or Digiexam —which enforce complete kiosk mode and prevent operating system-level workarounds.

If you have a specific operating system or device type (such as Chromebooks, iPads, or Windows laptops) or an LMS (like Canvas or Google Classroom) that you need to integrate with, let me know and I can help you find the best fit!
