Accessibility is most useful when it shapes the product from the start. The question is practical: can someone understand the next step, operate the control and recover if something goes wrong?
Follow a complete journey
Pick a task such as finding a lesson, submitting an enquiry or approving a record. Walk through it with a keyboard, on a narrow screen and with a larger text size. Check what happens when a field is missing or the network fails.
A visible focus indicator, a descriptive field label and a clear error message are small implementation choices with a direct effect on task completion. Status should be available as text, not only as a colour change.
Include the content
Explain unfamiliar terms, use meaningful link text and make the next action predictable. If video carries essential information, plan captions and an equivalent way to access that information. Translation needs review in context, including control labels and error states.
Inclusive access may also involve lower-bandwidth options, device constraints and pricing choices. Those are product decisions to assess for a particular audience, rather than a blanket claim that every current product already serves every need.
Use standards and observed behaviour
WCAG provides testable criteria for contrast, keyboard operation, labels, focus and other aspects of accessible web content. Use those criteria as a baseline and complement them with task-based testing involving the people the product is intended to serve.
Record the checks performed and unresolved issues. An automated scan can identify some failures, but cannot establish that an entire experience is accessible or understandable.
Treat inclusive use as an ongoing engineering and design practice, with specific checks and honest evidence.
