It’s helpful to survey your students before class begins to learn about their accessibility and/or technology needs. This contributes to students feeling welcome in your course and gives you practical information about both learners’ needs and whether to follow-up with specific resources.
There is a template accessibility survey (titled “[COURSE#] Accessibility pre-start Survey”) within the CTLI’s library of surveys that you can copy and adapt to your own course; instructions on how to access and make your own version are here: Center for Teaching and Learning Innovation (CTLI) Student-facing Surveys Library
