Getting Started Testing with JAWS

Basics of the Screen Reader

Testing screen reader accessibility is an essential step in reviewing your content. JAWS is a screen reader available for purchase for Windows that reads aloud page content and relevant semantic info (such as headings, lists, and links). Use the following guidance to get started testing with JAWS, and to get a more comprehensive picture of accessibility.

How to Get JAWS:  JAWS® Screen Reader

Browser Choice:
Screen readers work best with certain browser combinations. For JAWS the recommended browser is Chrome.

The JAWS key:

JAWS uses a modifier key, called JAWS key, that is combined with other keys for commands. It can be set by the user to be the either the CAPS LOCK, INSERT, or NUMPAD 0 key.

We'll use CAPS LOCK as our JAWS key, but use whatever JAWS key you prefer.

Upcoming Testing Training

Let's Start Testing

When testing, try not to use your mouse. Instead use keyboard controls for navigation. Throughout your assessment, consider:

  • Is any content being skipped that should be read?
  • Is any content being read that's not visible?
  • Are headings, links, and buttons announced?

ON:  Open JAWS from your list of programs.

OFF:  INSERT + F4

Note: Once JAWS is turned on, the behavior of your keyboard keys will change. For example, you won't be able to use CAPS LOCK to capitalize text while JAWS is on.

Change How Fast JAWS Talks

Using a slower speaking rate can help with comprehension as you listen during testing.

  1. In JAWS  menu select Options
  2. Then Voices, then Voice Adjustment
  3. In Voice section, adjust the Rate slower.

Add the Speech Viewer

This is a text box that shows what is being read by the screen reader. It can be helpful if you want to view text as you test rather than just listen.

  1. In JAWS menu go to Utilities
  2. Select Braille and Text Viewer and then Show Text Viewer

Read All Content

Use CAPS LOCK + DOWN ARROW to start reading all page content.

  • Is all content read aloud?
  • Is it read in a logical order that follows the visible page structure?
  • Do the names of items that you hear match the names you see?
  • Are images read with their alt text or skipped if decorative?

Navigate Interactive Elements

Interactive elements are things like buttons, links, and form fields. Use TAB to go forward through interactive elements. Use SHIFT + TAB to go backwards.

  • Can you navigate to all interactive elements?
  • As you tab, does the name of elements that you hear matches the name you see?

Select Links or Buttons

Use ENTER to select or activate certain elements.

  • Can you access (TAB) and activate (ENTER) these elements?
  • Does the visible name on the button match the name that you hear? Is it announced as a button?
  • Is the link text descriptive instead of vague, like "click here" or "read more"?

Navigate with Arrow Keys

Use ARROW KEYS to navigate options or maneuver content.

  • Can you go backwards and forwards through radio buttons?
  • Can you select and then navigate down through drop-down menus?
  • Can you navigate between tab panels or tree menus?
  • Can you maneuver sliders or select options for auto-complete?

Open Elements List

Use CAPS LOCK + F3 to open a list of page elements such as headings, links, and landmarks. Use the ESC key to close the elements list, if needed.
  • Are headings and links descriptive?
  • Are landmarks present, unique and being used correctly?
  • Review buttons and form fields, if any.
