Pearson supports only managed Chromebooks for secure testing. Both before you install TestNav AND prior to each testing session, you should check each device to ensure it is in managed status. 

During BOTH the infrastructure trial and the actual test, note which specific device each student uses during each test. The TestNav app saves SRFs to only one designated place on the testing device. If an error occurs, you can locate files only on that specific device.

Install TestNav

To install TestNav, first ensure each device's settings are set to keep local data to avoid accidentally deleting the SRF and log files. Then, you add TestNav as a kiosk app. 

Content filters and TestNav...

If your content filters are activated when a student signs in to the Chrome device, contact Pearson Support for additional URLs to add to your kiosk settings for URL blocking. TestNav does not require that the student sign in to the Chrome device. As a result, these content filters do not filter as intended during a TestNav test.


  1. Sign in to the Google Admin console for your domain, using your administrator account (does not end in
  2. From the Google Admin console home page, go to Devices > Chrome > Apps & extensions > Kiosks.

  3. Under Organizational Units, select the top-level organization that you want to apply these settings to. Then, select a child organization, if necessary. In the example below, Pearson is selected to give all Chromebooks within the Pearson organization access to TestNav. 
  4. Hover over the Add icon () and select Add from Chrome Web StoreDo not add TestNav from Google Play. Google Play contains TestNav for Android and not for ChromeOS.

  5. Search for TestNav and click Select.

  6. If prompted, accept the app permissions.
  7. In the panel on the right, set the app and extension policies.

  8. Click Save.

Note on accessibility tools/accommodations...

Students with accommodations or accessibility features enabled through their PNP or test form access those features within TestNav. ChromeOS has native accessibility features that might appear within a kiosk floating accessibility menu during testing. Technology personnel can disable this menu before testing to avoid it interfering with the student’s test.

Find and Set Up Response File Backups

TestNav has a default primary SRF save location for all computers and devices. For detailed information on saved response files (SRFs) and log files, see Understand SRFs and Log Files.

SFTP configuration is not supported by all assessment management systems. Consult your assessment management system user guide to determine whether the SFTP option is available.

Prior to testing, complete the following steps:
  1. Familiarize yourself with the default primary save location.

  2. Configure the secondary save location through your assessment management system. 
    The same secondary save location applies to all computers and devices. You only need to set this configuration one time.  

  3. Communicate SRF and log file locations/procedures to proctors (see Primary Save Location below).

  4. Note which student tests on which device during infrastructure trials and on test days.

Primary Save Location

On Chrome OS, the SRF default primary save location is not customizable. 

To find files on Chrome OS:

  1. Launch the TestNav app.
  2. Focus your cursor in the username or password field.
  3. Press <ctrl><shft>z, and the File Viewer box appears.
    If the File Viewer does not display, click on the window and then press <ctrl><shft>z again.
  4. Plug in a USB memory stick.
  5. Click the download button next to the srf and log file(s) you want to download.
  6. When the window opens, select the USB memory stick, and click Save.

ADAM users...

Do not continue on this page. For additional instructions on tests managed in ADAM, see Log in to a Test using TestNav.

Run App Check

To run App Check:
  1. Click or tap the appropriate icon for your test from the home page to go to the Sign In page.
  2. Click or tap the user drop-down menu, and select App Check.

App Check (without optional Configuration Identifier)

On the App Check page:

  1. Leave the configuration identifier field blank.
  2. Click Run App Check.

You see green checkboxes for Kiosk Mode Readiness and connectivity to TestNav, if the system passes. If one of these fails, you will see a Fail message and must check your connection and settings before running App Check again.

App Check (with optional Configuration Identifier)

If you have obtained a Configuration Identifier from your assessment management system:

  1. Enter it in the Configuration Identifier field. 

    The configuration identifier allows TestNav to also check connection to ProctorCache computers.

  2. Click Run App Check. 

  3. If ProctorCache connectivity fails, TestNav provides information for possible resolutions. Use this information to troubleshoot, and run App Check again.

Run Network Check

On the App Check page,

  1. Click Run Network Check.

  2. Estimate the number of devices that will connect to your network during testing, and enter it into the Number of devices field.

  3. Click Start Diagnostics Test.
  4. See your Test Results under Network Diagnostics to determine whether your network has sufficient bandwidth to test without ProctorCache.

Sign in to TestNav

  1. Power on the device, but do not log in. If before a secure testing session, check the device's managed status.
  2. In the lower left of the screen, select Apps > TestNav to launch TestNav.
    A message appears, informing you that you can use <ctrl><alt>s to exit Chrome OS when you first launch TestNav. This works only while the message displays.
  3. If you have not already done so, choose the appropriate icon for your test on the home page. If your test was selected before the test session, you see the Sign In page, rather than the home page.  

    1. If you need to select a different test, click the user drop-down menu at the upper-right of the page, and click Choose a different customer.

    2. Click the appropriate icon for your test.

  4. Start a test to ensure that you can do so without error.
    • If you see a Practice Tests link on the Sign in page, click Practice Tests and start a test.
    • If you do not see a Practice Tests link, use an authorization ticket from your student management system and start a test.

      Install TestNav

      TestNav program files are saved in Applications/TestNav.

      1. Download TestNav.

      2. Double-click the .dmg file (for example, testnav-1.4.1.dmg) that you downloaded. The TestNav install window appears.

      3. Drag the TestNav icon into the Applications folder.
      4. Eject the TestNav installer from Devices in the Finder sidebar. You can also eject it from the Desktop.

      You can copy the TestNav application and push it to student computers for mass installation.

      For macOS 10.14+, you must grant TestNav full privacy & accessibility control to administer secure tests. Click or tap System Preferences > Security & Privacy > Privacy. Scroll to Accessibility, and add or select TestNav.

      • Disable Siri and/or Dictation services before attempting to sign in to TestNav.

      • If you use computer restoration or imaging software (for example, Deep Freeze), exclude the Pearson directory and the logs directory, as these contain student backup files and logs for troubleshooting.

      TestNav App Updates

      TestNav program file updates are saved in {user_home}/Library/Application Support/Pearson. You must give students write access to the update directory.


      • Any necessary patch updates automatically install whenever TestNav starts or when a student attempts to log in. This ensures the update is implemented even if schools leave TestNav running over the course of a few days. 
        You can also push the latest TestNav update, rather than waiting until each student opens TestNav. To push an update, take a snapshot of the Pearson folder, and push that folder to all student computers.
      • Updates that require reinstallation are scheduled for winter and summer breaks.
      • Pearson will communicate all updates with instructions in advance.

      When you install TestNav, it creates the TestNav folder within the Pearson folder shown in the path above. The TestNav folder contains the following:

      • The update file folder, named with the update version number (for example, 1.4.1)
      • The default file, which stores the customer login preference for the next login 

      The login preference stored in the default file can change if you select a different customer from the Sign In page. You can set the default file to read-only to prevent students from overwriting it after you set your test preference.

      If you encounter any issues during an update, you can find the errorlog folder within the update folder (for example: 1.4.1 > update > errorlog). The errorlog folder logs any issues TestNav may encounter when it attempts an update. You can also delete the Pearson folder to reset TestNav, clearing out any updates stored in that directory.

      Set Up Response File Backups

      TestNav has a default primary SRF save location for all computers and devices. For detailed information on saved response files (SRFs) and log files, see Understand SRFs and Log Files.

      SFTP configuration is not supported by all assessment management systems. Consult your assessment management system user guide to determine whether the SFTP option is available.

      Before testing, refer to your assessment management system user guide to configure TestNav and complete the following steps. 
      1. Configure primary and a secondary save location through your assessment management system.

      2. Configure student accounts to have complete read, write, and delete access in these save locations.

      3. Communicate SRF and log file locations to test proctors.

      4. Give proctors access to SRF and log files by either of the following:

        • Grant admin rights to proctors on each testing computer.

        • Instruct proctors to access these files while the student is logged in to the testing computer.

      Default Primary Save Location 

      Operating SystemSRF LocationLog File Location
      OS X



      Pearson strongly recommends that you configure a network drive as a secondary save location to ensure that you do not lose responses, even if a student cannot continue to test on the same computer. 

  5. To shut down and exit kiosk mode after the app launches, hold down the Power button.

Run an Infrastructure Trial

Pearson strongly recommends running an infrastructure trial to verify the technology setup is complete and to familiarize teachers and students with the test. Use your training site through your assessment management system to complete the trial before the actual test day.
