Make sure you have this (or a similar) course accessibility statement displayed prominently on the main page of each course you teach:
Course Accessibility Statement:
With the abrupt transition to the online format, I have made every effort to make this course accessible to all students, including students with disabilities. If you encounter a problem accessing anything in this course, please contact me immediately by email so that I can support you. You may also contact the Accessibility Resource Center at 910.521.6695 or email@example.com.
Student ADA Accommodations:
If you have students in your classes who have already implemented accommodations, they may or may not need them in your online course as well. We recommend you reach out to students to ask if they still require the same accommodations
