This resource is designed to help you provide your students with accessible Microsoft PowerPoint presentations. The table below provides recommendations and links to appropriate guidance materials. Please note that the points raised here encompass both the values and ethos of the Universal design for Learning and the requirements of Accessibility legislation (Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018) relating to resources made available via websites, including the Blackboard VLE.
Microsoft provides a mechanism for checking the accessibility of documents in PowerPoint and a full description of the method for running this check is provided at the end of the table below.

Avoid combining colours of a similar tone, such as dark blue and black.
If you know that a presentation is to be delivered in a dark room it can be helpful if a dark background and light text are used.

ScreenTips can be employed to provide additional hyperlink information. (Screen Tips are added via the hyperlink set-up window).
Avoid using a full url in the body of the text.
