Oh Pearson definitely does thst as well. But not everyone lives near or has reliable transit to a testing facility. Online testing is essentially a requirement for those people.

They actually already do that. Many schools will have dedicated exam rooms setup (some are even certified by Pearson) where you empty your pockets before entering, cameras are trained on you while you take the test, recorded for future review if needed, the computer is configured to be locked down to only the test site and there's a test proctor actively monitoring as well.

Honestly just give me a printed packet in a classroom with a teacher watching the test takers any day
