Issues and Workaround for Assistive Technologies

Below is information on known issues and workarounds for specific types of assistive technologies. We will add to and update this list as more information becomes available. To report additional issues and workarounds, please email

Screen Readers (Updated 3/1/2019)

The following accessibility issues are still outstanding:

Known Issues Applying to All Screen Readers

  • Issue: If using Month or Week views in the Calendar, screen reader users will experience difficulties accessing information. (Reported: 5/4/2016)
    Workaround: Switch to Agenda view for the most accessible experience. After switching to the Calendar, select Agenda view by moving to the Calendar heading on the page.
    • If Agenda view is not currently selected, the first button past this heading will be called Warning: For improved accessibility, please use the "Agenda view."
    • Select this button to switch the calendar into Agenda view.
    • Agenda view provides the same functionality of other views, except the option to drag calendar events to different dates and times
  • Issue: In the Calendar, there are numerous actions which can cause a mini calendar to appear for screen reader users. This calendar is inaccessible. (Reported: 5/30/2016)
    Workaround: Ignore the Mini Calendar which appears in the Complementary landmark on the page and can be identified by a group of unlabeled buttons and a table.
    • Jump focus over the calendar by pressing the b key when on the unlabeled buttons which will move focus to the widget that allows showing and hiding calendars. This is the first element past the inaccessible calendar.

Issues Specific to Voice Over

  • Issue: When navigating over the file upload button in the Assignment Submission screen, VoiceOver does not always announce the correct description of the button.
    Workaround: To ensure VoiceOver reads all text relevant to buttons, set the speech verbosity to High. This can be done via the VoiceOver utility (Command+Option+F8). When using a laptop, it may be necessary to use the FN key as a part of this keystroke. This setting is located in the General category of the Verbosity options.

How To: Rearrange items in the navigation section of a course

Although Drag and Drop is not accessible, an alternative mode was implemented for screen reader users:

  • From the landing page for a course, select Course Settings.
  • Press Tab to reach the Settings button past the item you want to move.
  • Press Enter to select the Settings button and open a pop-up menu.
  • Use the Down arrow to place focus on the Move option and press Enter.
  • Focus will land in a dialog that contains a list of the course categories in a combo box and a group of radio buttons that allows you to select whether the item should be placed before or after the item selected in the combo box.
  • Press Tab to land on the group of radio buttons. Use the Up and Down arrows to select the desired option.
  • Press Tab again to move focus to the combo box where the course section is selected that the moved item will be placed adjacent to.
  • The last two items in the dialog that are accessible by pressing Tab are Cancel and Move buttons. Selecting these options closes the dialog and either performs the action or cancels changes.

How To: Change times of Calendar events in agenda view as an alternative to drag and drop.

  • Each Calendar Event is marked by a button.
  • If using NVDA or JAWS on the Calendar page, use H to move to the calendar heading and then B to move to each event which is marked as a button.
    • Select the Edit button in the pop-up by pressing B again to move to that button.
    • Once this button is selected, two of the items on the pages are edit boxes for setting the date and time of the event.
    • Move to these using E in NVDA and JAWS.
  • When using VoiceOver, once on the Calendar page, press Control+OPT+u to open the Web Item Rotor.
    • Use the Left and Right arrows to select Form Controls and then use the Up and Down arrows to select the event of interest.
    • Use these same instructions to select the Edit button in the pop-up.
    • Once on the page for editing an event, use the Web Item Rotor again in forms mode to select the edit boxes for changing the date and time of an event.
