A steady, relatively high-speed connection for the duration of your assessment will help prevent technical issues. To determine if your internet connection is generally reliable go to https://sourceforge.net/speedtest/ and check your results. Whether at home or at work, you should have:

Latency/Ping:< 25ms
Download Speed:> 15 Mbps
Upload Speed:> 2 Mbps
Packet Loss:0%

If your internet connection does not meet these requirements, we recommend that you use a different network or device.


If you are unable to access the platform or log in, forward these instructions to your IT Administrator at your workplace: “Please ensure that mycertlink.org is globally whitelisted, and that cookie and DOM storage are permitted for mycertlink.org”.

Check with your IT department to ask about the presence of a proxy server. While the presence of a proxy server is usually not a cause for concern, if you plan to answer questions in a workplace environment, you may also want to consider answering questions on a non-work network or computer to help ensure an optimal user experience.

If you encounter any technical issues, please navigate to the “Need Help” option on the CertLink dashboard to run a System Check. Contact your CertLink Board support agent if you have any questions or need further assistance.
