Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Combine automated checks with manual evaluation, assistive-technology testing, and input from people with disabilities in one planned, documented review. Define the product boundary, WCAG version and target level, and supported browsers and assistive technologies first; then explore key views and workflows, test a documented sample, and report what was—and was not—evaluated. A scan or a sampled audit is not proof that every part of a product is free of accessibility barriers.
What each testing method contributes
Accessibility methods answer different questions. Automated tools efficiently flag issues that can be checked mechanically, while human evaluation is needed for context, content, and many interaction questions. Assistive-technology checks examine the experience through the support baseline you declare. People with disabilities can contribute real-life perspectives that a checklist alone may not convey.
| Method | Useful for | Important limit |
|---|---|---|
| Automated or semi-automated tools | Finding mechanically detectable issues and making evaluation more efficient. | Tool output is only one part of an evaluation; investigate findings and check issues that require judgment manually. |
| Manual evaluation | Assessing content, context, and behavior against the selected WCAG requirements. | Requires a planned scope and suitable expertise; results depend on what was examined. |
| Assistive-technology testing | Checking sampled tasks with the browsers, assistive technologies, and other user agents in the declared support baseline. | Results apply to the combinations and tasks tested, not automatically to every environment. |
| Participation by people with disabilities | Understanding real-life experience and barriers during relevant tasks. | Complements, rather than replaces, systematic conformance evaluation. |
There is no universal automation-coverage percentage established by the sources cited here. Section508.gov describes automated, manual, and hybrid testing approaches and advises evaluating tools’ rule methods and accuracy against expectations. Choose a combination based on the product, its technology, the evaluation purpose, and the target—not a presumed percentage of criteria a scanner can cover.
Plan the evaluation before running tests
Set scope, target, and support baseline
Write down which product or parts of it are in scope, why you are evaluating them, which WCAG version and conformance level you are targeting, and the browser, assistive technologies, and other user agents that form your accessibility-support baseline. WCAG-EM 2.0 says Level AA is generally accepted and recommended, but the evaluation should explicitly select its actual target. WCAG-EM supports evaluations of websites, apps, and other digital products; it is a W3C Group Note that supports WCAG rather than adding requirements to it. Read the WCAG-EM 2.0 methodology.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Explore views and complete workflows
Inventory important views, content types, technologies, and functionality before choosing test cases. Include complete processes—such as sign-in or checkout where relevant—rather than checking isolated screens only. Record the settings, inputs, and actions needed to reach each view so another evaluator can reproduce the path.
Select and document a sample
Evaluate every relevant view when practical. If the product is too large, choose a structured sample of important or distinct views and functionality, and add random sampling where appropriate. Explain how the sample was selected and how each item is reached. A sample makes an evaluation manageable, but it cannot show that unexamined areas contain no errors.

Run the combined evaluation
- Apply the declared target. Evaluate sampled content and functionality against the WCAG requirements and accessibility-support baseline chosen during planning.
- Use tools as an efficiency layer. Record each tool’s name, version, and method. Review its rule approach and accuracy against your expectations; manually investigate findings rather than treating tool output as the final result.
- Inspect questions that require judgment. Manually assess the sampled content and interactions that cannot be settled by a mechanical check alone.
- Test real interaction. Where practical, exercise sampled tasks with the assistive technologies and user agents in scope. Involve people with disabilities when feasible to learn from real-life experience, while retaining systematic evaluation against the target.
- Record findings and limits. Tie findings to the view, task, environment, and method used, and note what was not evaluated.
W3C describes evaluation tools as a way to improve efficiency, not as a substitute for evaluation. For an overview of automated, manual, and hybrid approaches, see Section508.gov’s overview of testing methods.
Report results without overstating coverage
A useful report lets another person understand and repeat the evaluation. Include the product scope, purpose, WCAG version and target, support baseline, sample-selection method, test environment, tools and versions, assistive technologies, procedures, findings, and untested areas. WCAG-EM alone usually does not produce a whole-product conformance claim. Any public evaluation statement should identify the product and target and state its conditions.

Be careful with aggregate scores. W3C’s WCAG-EM 2.0 methodology says “there is currently no single metric that is known to address the required reliability, accuracy, and practicality.” A score may conceal context; if you publish one, explain its calculation so readers can interpret and repeat it. The W3C WCAG-EM overview notes that WCAG-EM 2 was published on 23 July 2026 and extends the earlier website-focused method to apps and other digital products.
