Important Information about Techniques
See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.0 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.0.
The purpose of this technique is to provide a label for objects that can be read by assistive technology. The aria-label attribute provides the text label for an object, such as a button. When a screen reader encounters the object, the aria-label text is read so that the user will know what it is.
Authors should be aware that aria-label may be disregarded by assistive technologies in situations where aria-labelledby is used for the same object. For more information on the naming hierarchy please consult the ARIA specification and the accessible name and description calculation in the HTML to Platform Accessibility APIs Implementation Guide. Authors should be aware that use of aria-label will override any native naming such as alt on images or label associated with a form field using the for attribute.
Resources are for information purposes only, no endorsem*nt implied.
Procedure
For each element where a aria-label attribute is present.
Examine whether the text description accurately labels the object or provides a description of its purpose or provides equivalent information.
Expected Results
#1 is true.
If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.
