This post is part of the accessibility series I am running. We will look at using media and images in questions and how to ensure these are accessible.
A number of media files can be included in a question/assessment. However, if you are interested in producing accessible assessments you should consider the following:

  • Ensure color is not the only way to distinguish among different pieces of stimulus or answers. Common forms of color blindness (affecting up to 5% of the population) could make answering questions difficult. You should, where possible, change how the information is portrayed or include other indicators.



When including graphics always include ALT (Alternative) text. This will be displayed when a participant hovers the mouse pointer over an image or if a screen reader is being used.

  • If you are using Adobe Flash media, make sure that it has been created in an accessible fashion.  Refer to the Adobe guidelines for Flash  and Captivate.
  • If you are using video or audio in a question you should include a transcript. You can include a transcript in several ways:
  • Link to a document that includes a transcript (Remember if you are including the transcript as a PDF you should also make sure this is accessible as well. See the Adobe guideline here)
  • Embed a YouTube video, using the Closed Caption feature to include subtitles of any dialog in the video.Provide a video transcript within an assessment, using Questionmark’s Side-By-Side template.

(My advice and recommendations may or may not be suitable for your particular situation, so be sure to take into account your organization’s accepted practices and pedagogy.)
