Does Mercer Mettl Detect Cheating?

2026-09-12

Mercer Mettl is built for proctored exams, and it shows. Camera, microphone, locked browser. It is normal to feel watched before you even start.

Here is what Mettl says on its own proctoring pages.

Yes, Mettl detects cheating signals when proctoring is turned on. It markets AI flags for faces, voices, phones and distraction, plus browser lockdown and human review. Mettl also admits its monitoring "does not have the capability to detect other devices directly."

What Mettl says its AI flags

Mettl's SecureProctor page lists "AI-based Proctoring through auto-generated flags for:"

• Facial detection
• Voice detection
• Mobile phone detection
• Distraction detection

Audio is watched too. Mettl lists "Automatic tracking of students muting their microphones" and says its SpeechSense feature "Accurately Identifies Count Of Unique Speakers In The Vicinity."

What the locked browser blocks

On the same page, Mettl says:

• "The Test Is Launched in Kiosk/ Lockdown Mode, Wherein Additional Tabs Are Disabled and Navigation Is Restricted."
• It "Restricts the Candidates from Using Cut/copy/paste During the Test."
• "Attempts to Navigate Away from the Test Window Are Notified in the Report."

Mettl also offers "mobile cameras as secondary devices" for a wider view of the room.

Who watches, and when

Mettl describes three types of proctored exam:

• Live online proctoring, "with a human invigilator monitoring candidates' screens in real-time."
• Recorded online proctoring, "with AI monitoring, later reviewed by human proctors."
• Advanced online proctoring, "without any human intervention, where advanced AI monitors and flags suspicious activities."

Which one you get depends on the organization running the test. Mettl does not publish which setup a given employer uses.

What the hiring team sees

Flags roll up into a "'Credibility Index' report to capture flagged instances and duration." Reviewers can "Review recorded footage to verify AI flags."

On screens, Mettl's FAQ says "online proctoring often involves recording the screen to monitor exam activity and reduce instances of cheating." It does not say which Mettl tests do this.

Staying steady under proctoring

StealthCoder is a desktop app that runs separately from the browser. It is an AI overlay that stays invisible during screen share, and it reads the problem on screen to help you work through it.
