Understanding Success Criterion 4.1.3: Status Messages

Research-assisted source review

What it supports
Important status changes must be programmatically determinable so assistive technologies can present them without unnecessarily interrupting work. Examples include submission success, error counts, search results, busy states and progress updates.
Where it may not transfer
This guidance establishes an accessibility requirement and examples, not the behavioural effect of feedback or the best message for a particular product. It applies to defined status messages, not every content change, and warns that excessive live announcements can make an interface too chatty.
