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. 

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.

Step-by-Step

  1. Sign in to the Google Admin console for your domain, using your administrator account (does not end in @gmail.com).

  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 app or extension by ID.
  5. Enter the Extension ID: mdmkkicfmmkgmpkmkdikhlbggogpicma
  6. If prompted, accept the app permissions.

  7. In the panel on the right, set the app and extension policies.

  8. Click Save.


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 should disable this menu before testing to avoid it interfering with the student’s test.

Find and Set Up Response File Backups

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.
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

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