Equivalent internet content:

Should provide a disabled user with content identical in information content to that used by a non-disabled user. For example, providing a text document in Braille or tape format is considered to be an equivalent version.

Alternative access:

Provides a disabled user with an activity that differs from that experienced by a non-disabled user, but the learning or informational objective should remain the same.

For advice on satisfying learning objectives with alternative means, contact the Educational Developers in the Centre for the Advancement of Learning and Teaching (CALT)
