Frequently Asked Questions

OPT & EOT Computing Requirements

What are the computer and internet bandwidth requirements for Online Proctored Testing (OPT) and Event Online Testing (EOT)?

The computer requirements for Online Proctored Testing (OPT) and Event Online Testing (EOT) are similar except for the bandwidth required. To enable multiple candidates to test simultaneously, EOT requires significantly more internet bandwidth than OPT.

For Online Proctored Testing (OPT):

The minimum and recommended computer specifications required for OPT workstations are:

TYPE MINIMUM RECOMMENDED
Internet Connection Wi-Fi connection Wired connection
PC Users Windows 10
  • Windows 10 S mode is not supported
  • Chromebooks are not supported
Windows 11
  • Windows 10 S mode is not supported
  • Chromebooks are not supported
Mac Users macOS 10.13 (oldest maintained version) macOS 10.15
Internet Browser
CPU
  • 2-core CPU
  • Less than 85% CPU usage
  • 4-core CPU
  • Less than 50% CPU usage

  • Less than 90% RAM usage
  • 16 GB
  • Less than 70% RAM usage
Connectivity Ports
1935, 843, 80, 443, 61613, UDP/TCP 1935, 843, 80, 443, 61613, UDP/TCP
Screen Size 15 in. 17 in. or larger (larger screens result in better candidate experience)
Screen Resolution 1366 × 768 1920 × 1080 and above
Accessories
 
  • Touchscreen monitor
  • Stylus
Internet Download Speed 1 Mbps 12 Mbps 
Internet Upload Speed
1 Mbps  3 Mbps 

For Event Online Testing (EOT):

  • When determining required internet speeds for EOT, count the maximum number of candidates (one device per candidate) and add an additional device for the Proctor.
    • For example, to determine the recommended internet download speed for an EOT test administration with 10 candidates, figure 10 candidates + 1 proctor = 11 devices × 12 Mbps per device = 132 Mbps total download speed.
    • Similarly, the recommended upload speed would be 11 devices × 3 Mbps = 33 Mbps total upload speed.
  • Computers used for Proctors must also use the Guardian browser to launch EOT exam(s) properly.

The minimum and recommended computer specifications required for EOT workstations are:

TYPE MINIMUM RECOMMENDED NOT SUPPORTED
Internet Service Source (ISP network) Non-cellular internet sources (Strong, stable, consistent, predictable internet source):
  • Broadband/Cable
  • Satellite

Cellular Internet Sources

  • Cellular/Mobile hot spots
  • MiFi devices
Internet Source Download Speed 2 Mbps (2048 Kbps) per device* 12 Mbps (12288 Kbps) per device*
<2Mbps (<2048 Kbps) per device
Internet Source Upload Speed  2 Mbps (2048 Kbps) per device*  12 Mbps (12288 Kbps) per device*   <2Mbps (<2048 Kbps) per device

*Use go.proctoru.com/testitout to perform a speed test.

Speed tests will provide an estimate of the available bandwidth for a single machine at a moment in time. Please note that other variables may impact the actual bandwidth during testing time, including but not limited to the physical network infrastructure in your testing room, other traffic on your network, etc. 
Internet Network

Wireless Local Area Network (WLAN)

  • Dedicated wireless internet network (wifi)
  • Private and password-protected access
  • Ensure only test takers are connecting on test day
  • Firewalls disabled

Local Area Network (LAN)

  • Dedicated hard-wired internet network (Ethernet)
  • Ensure only test takers are connecting on test day
  • Firewalls disabled
  • Access to network technical support professional on day of testing
