 * Due to the large number of manufacturers of these devices, NHA cannot fully guarantee compatibility with them and highly recommends that a test against the NHA system be performed prior to purchasing. Most of NHA’s content does not require a heavy amount of processing power and memory usage. NHA simulation experiences do require a substantial amount of both, which may occasionally cause issues loading simulation content.

** Due to the screen size and often running in a “mobile” mode, NHA does not recommend using mobile devices to access the NHA site or other content not offered through the NHA mobile application.

 Additional Configuration Notes

  • NHA recommends using wired network connections for proctored testing. Wireless/Wi-fi connections may be unreliable and could negatively affect testing.
  • NHA recommends a download speed of 10Mpbs or greater to consistently access all content. A network speed test can be found at http://www.speedtest.net if download speeds are unknown.
  • Android's default browser is not supported; download Chrome for a better experience.
  • Clear browsing history and exit the browser prior to any testing.
  • Depending on your institution’s setup, they may need to allow *.nhanow.com and *.kognito.com through all proxy/caching servers.
  • Satellite ISPs: NHA’s website functionality depends on direct connections to our website and databases to accurately display content. Because many ISPs cache webpages rather than allowing connection to the originating website, we are not able to guarantee performance of our website over a satellite connection.
  • NHA internally tests their products using JAWS and NVDA to promote WCAG 2.0 compliant operations for assistive reading.
