Before requiring a tool or external resource
- Ask the vendor/publisher for current accessibility documentation (often a VPAT/ACR).
- Look beyond the document: test the actual student task with keyboard navigation and common accessibility expectations.
- Ask what known barriers remain and the vendor's remediation timeline.
- Identify an equivalent path for students if the required experience is not accessible.
- Recheck after major product changes; accessibility documentation can become stale.
For publisher materials
Slides, ebooks, homework systems, videos and documents supplied by a publisher still become part of the course experience when faculty require them. Prefer an accessible version or equivalent resource rather than waiting for a student to report a barrier.
