How to Proctor Google Forms Exams: 5 Methods That Actually Work

⚡ Quick Answer The 5 most used methods to proctor Google Forms exams are: ExtendedForms add-on, Google Meet manual monitoring, lockdown browsers, third-party AI proctoring (like MonitorExam), and Google Workspace Locked Mode. For small classes, ExtendedForms works. For anything high-stakes or large-scale, MonitorExam is the strongest option.

Google Forms is the go-to tool for millions of teachers running online exams. It's free, familiar, and requires zero setup. But it has one critical gap: no built-in proctoring.

So what do teachers actually do?

We scoured Reddit's r/Teachers, r/EdTech, and r/GoogleWorkspaceEdu to find the most recommended methods — then added honest pros, cons, and scale ratings for each.

Why Proctoring Google Forms Is Harder Than It Looks

Before diving in, it's worth understanding what you're actually trying to prevent:

• Tab switching — opening Google, ChatGPT, or notes in another tab
• Identity fraud — a different person taking the exam
• Screen sharing — sharing the screen with someone off-camera
• Copy-paste — copying questions into AI tools
• Collaboration — two students working together remotely

Google Forms alone catches none of these. Here's what actually helps.

Method 1 — ExtendedForms Add-on

ExtendedForms is a Google Workspace Marketplace add-on that plugs directly into Google Forms and adds a lightweight proctoring layer.

What it adds:

• Countdown timer with auto-submit when time runs out
• Restricts to one attempt per respondent
• Welcome screen with instructions before the exam begins
• Basic tab switch detection (limited)
• Live response monitoring dashboard

What it doesn't do:

• No webcam or face tracking
• No identity verification
• No AI anomaly detection
• No detailed integrity report per student

Best for: Class quizzes, homework checks, low-stakes tests where you just need a timer and one-attempt restriction.

Reddit verdict: "ExtendedForms is the easiest way to add basic proctoring to Google Forms — takes 5 minutes to set up."

Method 2 — Google Meet + Manual Monitoring

A widely used DIY approach: run the exam in Google Forms while supervising students live on Google Meet.

How it works:

1. Students open the Google Forms exam link
2. Students join a Google Meet session simultaneously
3. Teacher watches camera feeds while students complete the exam
4. Students are asked to keep cameras on and screens visible

What it catches:

• Students looking away or leaving the room
• Obvious phone or notes use
• Someone else in the room

What it misses:

• Tab switching (teacher can't see the browser)
• Screen sharing or second devices
• Students whispering or texting

Best for: Small classes (under 20 students) where the teacher can actively watch each feed.

Reddit verdict: "Works fine for 15 students. Completely unmanageable for 60."

Method 3 — Safe Exam Browser (Lockdown Browser)

Safe Exam Browser (SEB) is a free open-source lockdown browser that restricts students to a single exam window — no tabs, no apps, no copy-paste.

What it does:

• Locks the device to a single browser window
• Disables keyboard shortcuts, right-click, and screen capture
• Prevents switching to other applications
• Works with Google Forms via a direct URL

Limitations:

• Requires installation on every student device — a major barrier
• Doesn't work on iOS or Chromebooks without workarounds
• No webcam monitoring or identity verification
• Students on personal devices can simply use a different browser

Best for: Computer labs where the school controls device configuration.

Reddit verdict: "Great in theory, nightmare to deploy on personal devices. Half my students couldn't get it running."

Method 4 — Google Workspace Locked Mode (Chromebook Only)

Google Workspace for Education includes a Locked Mode for Google Forms that restricts students to a single tab during the exam.

What it does:

• Prevents tab switching during the exam
• Blocks access to other apps and websites
• Works natively with Google Forms — no add-on needed

Critical limitation:

• Only works on school-managed Chromebooks
• Does not work on personal laptops, phones, tablets, or Windows/Mac devices
• No webcam monitoring or identity verification

Best for: Schools with a full managed Chromebook fleet.

Reddit verdict: "Perfect if your school is 1:1 Chromebook. Completely useless otherwise."

Method 5 — MonitorExam (AI Proctoring)

MonitorExam is a dedicated AI proctoring platform that works alongside Google Forms. Teachers paste their Google Forms link into MonitorExam — students go through a proctored session before accessing the form.

What it does:

• Browser lockdown — blocks tab switching, copy-paste, screen sharing
• Webcam monitoring — face tracking, presence detection, multiple people detection
• Identity verification — ID upload before exam begins
• AI anomaly detection — flags unusual behaviour patterns automatically
• Real-time teacher alerts — instant notifications even when teacher is offline
• CredScore report — integrity score + full audit trail per student
• Works on any device — no installation required
• Google Forms compatible — paste any Forms link

What makes it different from the others: Unlike add-ons or DIY methods, MonitorExam combines all security layers in one place — and works at scale. Whether you have 10 students or 10,000, the setup is identical.

Reddit verdict: "Combine Google Meet + MonitorExam for strongest proctoring. MonitorExam handles the tech, Meet gives you a visual on the room."

Side-by-Side Comparison

Which Method Should You Use?

The Reddit Consensus

After reading hundreds of threads, the pattern is clear:

• For lightweight quizzes: ExtendedForms is the community favourite — fast to set up, no cost, good enough for most classroom use
• For anything high-stakes: Teachers consistently recommend a dedicated proctoring tool, with MonitorExam and similar platforms cited for their AI monitoring and scalability
• The hybrid approach: Many teachers combine Google Meet (for visual presence) with MonitorExam (for technical security) — this covers both the human and AI angles simultaneously

The biggest frustration teachers express is discovering too late that their chosen method has a gap — a student found a workaround, or the tool didn't work on half the class's devices.

Frequently Asked Questions

Can Google Forms detect cheating without any add-on? No — Google Forms records responses and timestamps only. It cannot detect tab switching, identity fraud, screen sharing, or external help without a proctoring tool.

Is ExtendedForms enough for a school exam? For low-stakes class tests, yes. For entrance exams, certifications, or any exam where results matter significantly, it lacks webcam monitoring and identity verification.

Does MonitorExam work with Google Forms? Yes — paste your Google Forms link into MonitorExam and students go through the proctored session automatically before accessing the form.

Can students cheat on Google Meet supervision? Yes — teachers on Google Meet cannot see what's on the student's screen, only their face and room. Tab switching and off-screen devices go undetected.

What is the easiest proctoring setup for Google Forms? ExtendedForms for basic use, MonitorExam for secure use. Both require no student installation and work in under 5 minutes.
