Assessment Technology Guide
Use this guide to prepare your devices, network, and browser for Avant testing. Before testing begins, run the Technology Check on each device you plan to use.
Network Requirements
Firewall Access
- Allow inbound and outbound HTTP/HTTPS traffic to *.avantassessment.com over TCP ports 80 and 443.

iPad Audio Issue 
NOTE: Apple iPads currently have a known issue with audio recording and playback. This issue occurs when test takers play back recorded audio. During playback, the volume is very low and may not be audible to the test taker. The audio is being recorded at its proper volume and is only reduced during playback on the test taker device. Administrators can check the recording quality by accessing the speaking samples via the Teacher/Administrator report access.
Suggested Strategy: Having test takers complete the Speaking section on a different device is the best option. If that is not possible, direct the test taker to speak loudly during the recording using an attached microphone and then turn the volume up to high during playback of the audio. Remind test takers to turn the volume down, once they have completed the speaking section of the test.
Browser Permissions and Settings
Before testing, make sure:
- Cookies and JavaScript: Confirm that they have not been disabled.
- Managed devices: IT staff should confirm that browser or device policies do not block microphone or camera access.
- Browser window: Open the assessment in a regular browser window. Incognito and Private Browsing modes are not supported.
Security Preparation
Virus Check
Before completing an Avant Assessment on a personal device, we suggest completing a virus check on the operating system on that device. This is to ensure that there is no malware present on the device that could compromise the testing data.
Browser Extensions
We recommend disabling the Grammarly browser extension during testing as it interferes with virtual keyboards. There may also be other extensions which could cause interference and disabling all extensions may be helpful.
