Test Device Readiness

Assesment Devices

Pearson’s TestNav assessment engine is web based and does not require a client install on devices using Macintosh and Windows operating systems. TestNav does require Java environment 1.5 and above to provide security during the assessment on devices using Macintosh and Windows operating systems. There are also browser specifications related to the devices’ operating system. On iPads and Chromebooks Pearson has developed native applications that require installation and configuration to perform optimally.  


Identify Assessment Devices

Environment Security 

  • Make certain that the student have permissions to save the student response files (SRF) to the designated primary and secondary directories.
  • Ensure that any applications on testing workstations that could take over the computer thereby causing the testing application to close (i.e. screen savers, scheduled virus scans, operating system updates, etc.) are disabled.

Device Verification

  • Complete System Check for TestNav.
  • Verify that all workstations using Macintosh and Windows operating systems meet minimum requirements for test delivery and all third party software dependencies and updated versions of software have been installed. For proper functioning of the system, the following must be enabled:
    • Java runtime plugin version 1.5 and higher,
    • Browser window Pop-ups for Pearson sites,
    • Local File access to home directory.
  • Complete System Check verification on student computers used for assessment.
  • If the devices are similar, you may sample 2 to 3 devices in an assessment environment.

Windows XP Devices

Schools testing with XP devices must install HTML 5 compliant browser such as Firefox or Chrome to comply with TestNav 8 requirements.

Apple Devices

Setting Safari 6.1 to Allow TestNav 8

    • Safari for Mac OSX 10.7.5+ and Mac OSX 10.8,  In this version Apple has taken steps to protect users by limiting what applications/software can write to the hard drive. However, TestNav needs to be able to write to the hard drive in order to function. Safari security preferences must be configured to allow to write to the computer's hard drive.


Java Configuration Macintosh and Windows operating systems.

  • Java Enabled in Web Browser.
  • Java Security set to Don’t Block & Run for TN8.
  • Eliminate the Java prompt.

 1.       Find the Java Control Panel and open it.

§  In Windows, look for Java in the Control Panel.

§  In Mac OSX, look for Java in System Preferences.

2.       Select the Advanced tab.

3.       Change the setting shown to Enable - hide warning and run with protections.

Managing iPads for Secure Testing

There are several options for districts to manage multiple iPads for secure testing.

  • Manually configure iPads for single app mode via Guided Access (iOS 6 and above).
  • Enable/Disable single app mode with Apple Configurator via USB (iOS 6 and above).
  • Enable/Disable single app mode wirelessly via Apple Profile Manager or third party Mobile Device Manager (MDM) (iOS 6 and above).
  • Enable/Disable app requested single app mode via third party MDM (iOS 7 and above).

Chromebooks & Computer-Based Testing

Pearson has developed a Chromebook TestNav app available from the Chromebook app store

  • Chromebook app is available at no cost.
  • Encrypted Student Response Files (SRFs) are saved on the student device as the student tests.

LEAs must take steps to configure Chromebooks to deliver tests securely. 

  • Chromebooks must be configured for kiosk mode whenever TestNav is launched.
  • LEAs can configure Chromebooks via the Chrome Admin console.

Verify TestNav will Load on the Device

1.       Start a Browser or App.

2.       Go to this address: or http ://

3.       Enter the following credentials in the login screen:

·         Username: username

·         Password: password

4.       Choose "Sign In".

5.       Click the "Start Test Now" button.

6.       If you see the "Congratulations" screen then your computer is correctly configured to run TestNav.

Virtual Devices and Online Assessment

There are many different types of virtualization technologies in use in school environments, many of which have broadly different implications on both test security as well as the potential for performance impacts to a student experience. The DTC must ensure virtualization solutions for online testing can both ensure appropriate test security during the assessment as well as provide a comparable student experience in order to prevent performance issues from impacting student performance on the assessments.
