Resumé	Web accessibility evaluation assesses how well digital content conforms to the Web Content Accessibility Guidelines so that it can be used by people with a wide range of disabilities. WCAG 2.0, published as a W3C Recommendation in 2008 by Caldwell, Cooper, Reid, and Vanderheiden, organizes requirements under four principles—content must be Perceivable, Operable, Understandable, and Robust (POUR)—each broken into testable success criteria graded at conformance levels A, AA, and AAA. A rigorous evaluation combines three complementary methods: automated tools that scan for machine-detectable issues, manual expert inspection against the success criteria, and testing with assistive technologies such as screen readers and keyboard-only navigation. The evaluation determines whether the content satisfies all success criteria up to a target level and yields a conformance claim. Because no single method catches every barrier, the strength of the assessment lies in layering all three.	An accessibility audit is a systematic survey of a built environment that measures its features against accessibility standards or codes to identify, classify, and prioritize barriers facing disabled people. The auditor inspects elements along the chain of use—approach and parking, the entrance, internal circulation, sanitary facilities, signage, and controls—taking concrete measurements such as door clear widths, ramp gradients, and reach ranges. These measurements are checked against the criteria in the governing standard, and any element that falls outside the required range is recorded as a barrier. Barriers are then classified by severity and turned into a ranked remediation plan. Framed by the WHO International Classification of Functioning, Disability and Health, the audit treats the physical environment as an environmental factor that can either enable participation or, when it imposes barriers, produce disability.
