AI Overlay for Meazure Learning (Yardstick / Scantron) on Mac
Meazure Learning (formerly Yardstick Assessment Strategies and Scantron) administers professional licensure and credentialing exams across healthcare, finance, and HR. Its remote-proctoring app is ProctorU's Guardian Browser - a clue that Meazure relies on the same capture pipeline.
Meazure Learning brokers proctoring through partners; in 2025-2026 most Meazure deployments use Guardian Browser, the same Chromium fork ProctorU uses for its Live+ product. Guardian captures via ScreenCaptureKit on Mac, so the privacy flag works exactly as it does for ProctorU. The behavior detection, room scan, and ID check are unchanged from the ProctorU experience; only the branding (and the test sponsors) differ. LDBypass' overlay is invisible across the whole stack.
Key points
- Meazure Learning runs licensure exams for HR (SHRM-CP), nursing, and a number of medical specialties.
- Guardian Browser detects screen-recording apps by name; LDBypass uses a randomized innocuous bundle ID per build.
- A live proctor verifies your ID and watches your camera; the screen feed they see has already been filtered by ScreenCaptureKit.
- For some Meazure programs, you can choose a testing center instead of remote; that path is unrelated to the overlay.

Common questions
Is Meazure Learning the same as ProctorU?
They are separate companies but Meazure currently uses ProctorU's Guardian Browser as its remote-proctor client. The technical surface is the same.
Does the overlay support the SHRM-CP / SHRM-SCP exams?
It works alongside Guardian Browser, which is what SHRM uses. Whether AI use is allowed in your specific program is a policy question we do not answer.
Can I use the overlay if my exam uses Examity instead of Guardian?
Yes - Examity's capture path also honors window privacy. See our Examity guide for the specific setup notes.
