It appears to be exposed properly in the accessibility tree from what I've seen using MSAA/UIA, and it's announced properly using JAWS, NVDA, and VoiceOver as the three primary screen readers. I'd be surprised if it didn't work using TalkBack as well on the Android, or in ChromeVox in Chrome.
I'm not sure about ZoomText since it's not something I use personally. It's worth verifying though if anybody has it running.

  Can you clarify what you mean by works?  Is it exposed through the accessibility API (MSAA, UIA, etc.) or detected by assistive technologies such as NVDA, JAWS, ZoomText, etc. when used with these browsers.  I think it's important to consider both scenarios.

    Hi Geri,

      Easiest way to make sure  screen reader users know a certain field is required, in my opinion, is to add aria-required="true" to the input tag.

    According to <http://www.html5accessibility.com/> HTML5's required attribute was already supported by Firefox 15 and Chrome 21 but not accessibility-supported by Internet Explorer 10. 
    Is aria-required better supported by assistive technologies? 

    Best regards,


    For example for a first name text field:

    <input id="first-name" type="text" maxlength="50" value="" name="rel_first" aria-required="true" ></input>

    I also recommended, here at MD Anderson, since most of our forms can get pretty lengthly, to add at the beginning of the form "All fields are required except those marked as optional.", and then only mark the optional fields with the word "Optional".  Makes it clearer and cleaner.

    If a required field symbol is on screen, immediately to the left of a form field, but outside the label tag, so that a screen reader user has to exit Form mode to see it, does that violate that a required field must be programmibly determined?
