Testing Center vs Online Proctoring
7 minute read - Updated: November 2026
The testing center was the gold standard for exam integrity because it controlled the room. Online proctoring won on access and cost. For years the choice was a trade between the two. Device-level proctoring has narrowed the gap, because the thing a testing center controls best, the computer and what is running on it, can now be checked remotely. This guide compares the two settings on integrity, cost, access and the test-taker's experience, and sets out when each is the right call.
What a testing center controls
A testing center provides a locked-down computer, a proctor in the room, an identity check at the door and no personal devices. Its strength is physical: nothing runs on the machine that the center did not install, and nothing enters the room that the proctor did not allow. Its weaknesses are capacity, cost, geography and scheduling. It also does not scale to a course with hundreds of students or to a candidate pool spread across time zones.
What online proctoring controls
Online proctoring moves the exam to the test-taker's own computer and room. Live and recorded proctoring recreate the proctor through the webcam. Lockdown browsers recreate the locked-down computer inside the browser only. Device-level proctoring recreates it on the whole computer by checking what applications and windows are present, whether remote control or a virtual machine is in use, and whether a second device is nearby. What online proctoring cannot do is control the room physically; it can only see into it.
Side by side
| Factor | Testing center | Online proctoring with lockdown browser and webcam | Online proctoring with device-level checks |
|---|---|---|---|
| Controls what runs on the computer | Yes | Browser only | Yes |
| Sees desktop AI assistants and overlays | Yes (none installed) | No | Yes |
| Identity check | In person | Webcam or ID photo | Webcam or ID photo, optional |
| Second person or device in the room | Proctor | Camera frame only | Camera frame plus network and overlay checks |
| Capacity | Limited by seats | Unlimited | Unlimited |
| Cost per session | Highest | Low | Low to moderate |
| Scheduling | Fixed slots | Flexible | Flexible |
| Accessibility accommodations | On site | Configured in software | Configured in software |
| Evidence for an appeal | Proctor's statement | Recording and flags | Recording, flags and device events with timestamps |
When the testing center still wins
Licensure and certification exams with regulatory requirements for in-person administration. Exams where the test-taker population cannot be assumed to have a suitable computer or connection. Situations where the organization needs physical control of exam content, such as paper-based components or secure item banks.
When online proctoring wins
Any exam where access, capacity or cost matters more than physical control, which is most course exams, hiring assessments and professional training exams. Any exam where the primary threat is AI assistance on the test-taker's own device, because that threat is invisible to a testing center's proctor too unless the center controls the machine, and device-level proctoring controls the machine remotely.
The hybrid most institutions land on
In-person exams on student laptops in a classroom, with device-level proctoring running, give the instructor the room and the computer at once. Remote exams use the same configuration without the room. The policy, the student notice and the reports are identical, which is simpler for the integrity office and fairer for students.
Frequently asked questions
Is a testing center more secure than online proctoring?
For physical control of the room, yes. For what runs on the computer, device-level online proctoring matches it, and it produces a timestamped record a proctor's memory cannot.
Can online proctoring be used for in-person exams?
Yes. Device-level proctoring runs on student laptops in a classroom with the same settings as a remote exam.
Which costs less?
Online proctoring, by a wide margin per session, once staffing, space and scheduling are counted.
What about students without a suitable computer?
Institutions typically keep a small testing-center or loaner-laptop option for those students; the policy should state it.
Do accreditors accept online proctoring?
Most do for course exams. Licensure bodies set their own rules; check the specific requirement.
