WCAG 3.0 Timely and targeted guidance Outcome

Provides notification when the error occurs and identifies the source of error so users can readily refocus and remedy the error.

Barriers Encountered

Error source is not visually identified
Error source is not programmatically identified
Error source is not programmatically associated with error message
Error source is not accessible to assistive technology
Error source indicator is not identifiable (e.g., not recognizable as an error source indicator)
Error source indicator is not legible (e.g., not distinguishable)
Error notification does not occur at time of error
Time-limited error notification limits access to instructions
Error source visual label is not the same as its programmatic label, making it difficult to move focus using speech
Error message doesn’t match source: Error message provides a different, ambiguous, or incomplete field label than the searchable visual label, making it difficult to search for the term in the form.

Visual error source indicator: User needs a visual indicator of the error source so they know which component is the source of the error.
Error message provided when error occurs: User needs an error message that is provided when the error occurs so they can readily refocus on the source of the error.
Error message persists: User needs an error message that persists until the error is remedied so they can access the remedy instructions for as long as it takes to address the error.
Error message linked to error source: User needs an error message that is linked to the error source so they can readily move focus to invalid inputs to correct them.
Error message focused on reload: User needs an error message that is focused when the page reloads so they know there was an error

High-contrast error source indicator: User needs a prominent high-contrast error source indicator so they can identify the error source.
