System Requirements for Mercer | Mettl Assessment Platform

Mettl assessment can either be

  1. Proctored- Using your live-video feed from your integrated webcam/USB webcam, you will be monitored by remote proctors or Mettl’s AI system.
  2. Non- Proctored- No-live video feed is streamed. Hence no monitoring by remote proctors.
Both proctored and non-proctored assessments can be run on simple browsers like Google Chrome/ Firefox/Safari etc( details given below) or a special screen lockdown browser called Mettl Secure Browser(MSB).

With the following basic system requirements checklist, you can ensure that you launch Mettl assessments without any difficulty.

  1. For webcam proctored assessment- 512 kbps
  2. For non-proctored assessment-256 kbps.
You can check your network speed using the following two websites:

  2. http://www.speedtest.net

If your network speed is above the advised speed, you should not a face a problem while attempting the assessment

3. Browser Settings: Once you have the latest supported browser versions, you may easily start the assessment. However, in a rare case you may face difficulty in starting the assessment, due to the pop-up blocker setting of your browser. Here is what you can do to fix this:


  1. Use the “allow once/always” pop-ups function from your browser settings to allow assessment window to open
  2. Optionally, you may disable the pop-up blocker for the duration of the assessment. Here is how you can do it:
    1. For Mozilla Firefox on Windows: Go to ‘Tools’ --> Select ‘Options’ --> Click ‘Content’ tab and then uncheck ‘Block Pop-up windows’  check box.
    2. For Google Chrome: Go to ‘chrome://settings/’ --> Click on 'Show advanced settings' (at the end of the page). Under 'Privacy', click on 'Content Settings' --> Under 'Pop-ups', select ‘Allow all sites to show pop-ups’ --> Click on Done.
After performing the above steps, please restart the browser.
