Chromebook Magnifier is a basic magnification tool built into the Chromebook operating system. Other accessibility features that may be useful for students with visual impairments are Larger Mouse and High Contrast view. Chromebooks also come with a native screen reader program called ChromeVox. This program is not supported for testing at this time.

Although the native screen magnifier in the Chrome OS will work with MAP Growth assessments, there are some limitations. Most notably, the student may need to decrease the magnification level in order to complete drag and drop questions as you can only drag items within the zoomed screen. For this reason, students who need magnification may have a better testing experience on another supported device. See Testing visually impaired students in MAP Growth.

Additionally, the Chromebook Magnifier does not work in the Chromebook Kiosk App at this time.

If you would still like to use Chromebook Magnifier please follow the steps below:

Enable screen magnifier for user accounts:

  1. Log into the Chromebook.
  2. Click on the account picture in the lower right corner to access the system menu.
  3. Select Settings > Show Advanced Settings.
  4. Select Accessibility.
  5. Under the Accessibility section, select Enable Screen Magnifier or High Contrast.
  6. Close the Settings window.
  7. Open Chrome and go to
: The steps above assume that Accessibility is not an option on the system menu by default. If there is an Accessibility option when you click on the account picture in step 2, you can skip step 3. If you are configured for public sessions, step 7 is not necessary.

After you've enabled the screen magnifier, you can adjust it from your keyboard by pressing Ctrl + Alt + Brightness up or Brightness down. To pan the view around, move your cursor past the edge of the screen.

You can also enlarge the cursor to make it easier for the student to see. Select Settings > Show Advanced Settings > Accessibility and choose Show large mouse cursor.

Zoom in and out without Magnifier

When testing in the Chrome browser or the app, you can use the Ctrl + and Ctrl - keybindings to zoom in and out, without using Chromebook Magnifier. This is a good option if you just need to make the text or font size larger. However, in the Chrome app, you may need to zoom out (Ctrl -) to click on the Next button or see the full item.
