I read a lot of reports of eproctor'd tests being cancelled by rando e-proctors with zero recourse. There are three problems. The first is some of these tests cost hundreds of dollars, although I suppose getting kicked out of uni for cheating would be even more expensive, its just a huge risk to e-proctor compared to the human touch at my local test center. Secondly there is no feedback no oversight and no escalation procedure for most e-proctor systems that I'm aware of, some amazon turk nobody can cancel your test on you for any reason they feel like with zero recourse and you're out all the money and theres absolutely nothing you can do about it. Infinite power with no oversight will be infinitely abused. Thirdly the demands for a sterile test location were kind of a PITA. Honestly its easier to go to a test center than to provably and verifiably remove every book and piece of paper and anything with writing on it, from my office at home. I need to remove the kids from the house as any sight of another person is an instant disqualification and loss of my expensive test fee. I can't take it outside what if my neighbor starts mowing the lawn or it starts raining, instant fail when I leave the camera view. I have to silence every electronics device in the house because any interruption is again another forfeited expensive test.
(edited to add, I remember another complaint about e-proctor that to prevent brain dumps and copying questions out of their "secret test" any mumbling or even facial expressions were considered an autofail according to some online reports of people taking my test. I did the net+ and found it quite easy but sure enough I can't discuss for NDA reasons or whatever but I was eye rolling "you gotta be kidding" about one question and at a testing center locked in a room alone nobody cares when I roll my eyes but that would have cost me $350 if I did e-proctor testing.
also to prevent copying their top secret test they needed proof I had no electronics devices in sight, so it wasn't just removal of all paper products but anything electronic had to be removed from my office/lab it was just ridiculous)
Its just easier and faster and vastly less stressful to get out of the house and test onsite at the nearest Vue facility, which is a school I formerly attended LOL.
