Build accessibility evaluation into the full product lifecycle: define what you are evaluating and the WCAG conformance target, map important screens and user journeys, choose a representative sample, combine automated checks with informed manual review, involve people with disabilities where possible, and track findings through fixes and retesting. No single scan, checklist, or user test can establish accessibility on its own.
Start with a lifecycle, not a final audit
Plan evaluation during design and implementation, then continue through release and maintenance. A late audit can reveal barriers, but gives the team less opportunity to address them as part of ordinary product work. Include accessibility checks in design reviews, development, content production, quality assurance, and recurring maintenance.
W3C’s guidance is to integrate accessibility “from the beginning and throughout the project lifecycle — in planning, design, and development.” The practical implication is to schedule checks when the relevant work is happening, not just before launch.
Define the goal and scope
Write down what the evaluation is meant to support: internal improvement, a release decision, procurement, ongoing monitoring, or a conformance report. Identify the product and version, the user journeys and content in scope, and the applicable WCAG conformance level. Contracts, organizational policy, or jurisdiction may affect the target; there is no single target established here for every product or location.
#1 Best Overall
Keep four different activities distinct. A conformance evaluation assesses a defined scope against WCAG; developer checks catch issues during implementation; expert manual review applies human judgment to product behavior; and evaluation with people with disabilities brings real-world interaction experience into the process. These activities complement one another, but are not interchangeable. WCAG-EM is an evaluation methodology that supports WCAG conformance evaluation; it does not add WCAG requirements or act as a separate conformance standard.
Inventory the product before choosing tests
Map the surfaces and states people actually use. Include more than the home page or the easiest route through the interface.
- Views or screens, including mobile or platform-specific experiences where relevant.
- Essential tasks and their complete journeys, such as sign-in, search, purchase, submission, or account management.
- Repeated components, interactive states, validation errors, dialogs, menus, and success or failure messages.
- Content types and technologies, including documents or embedded content that are part of the product experience.
- Restricted areas, such as password-protected workflows, when they are in scope.
This inventory informs both test coverage and tool choice. It also makes omissions visible before an evaluation is reported.

Choose a representative sample deliberately
Evaluating every view may not be practical. When sampling, include common views, essential functionality, different content and sample types, the technologies the product relies on, and any other relevant cases. Consider how consistent the implementation is, what earlier evaluations found, and how much confidence the decision requires.
WCAG-EM 2.0 notes that a higher-confidence evaluation often calls for a larger sample; prior automated and manual results can also inform the required size. There is no universal sample count that fits every product. Record how the sample was chosen and what it leaves out, so readers of the report understand the limits of the result.
Combine automated checks and human evaluation
Automated tools can find potential issues efficiently and help reviewers focus their effort. They cannot assess every accessibility aspect or determine accessibility by themselves; results may also be false or misleading. Treat a tool finding as evidence to investigate, not as a conformance verdict or a substitute for judgment.
Choose tools for their role and the product under test. A team may need a combination of automated checks, tools that support manual inspection, and tools that simulate parts of a user experience. Coverage varies: tools may focus on websites, documents, applications, or particular formats and technologies such as HTML, EPUB, ARIA, CSS, SVG, or PDF.
Compare tools against the actual workflow
- Purpose: automated checks, manual review assistance, or user-experience simulation.
- Product and format coverage: the web, mobile apps, documents, and the specific formats and technologies in scope.
- Scope and access: whether it evaluates one view or groups of content, and whether restricted areas can be reached when needed.
- Standards transparency: supported standards and, where relevant, information about ACT Rules implementation.
- Workflow fit: browser extensions, authoring plugins, command-line tools, desktop or mobile applications, or online services.
- Reporting: whether findings can be exported and understood in the context of the evaluated content.
- Team fit: cost or licensing, required skills, operating systems, browsers, languages, and the accessibility of the evaluation tool itself.
W3C notes that needs vary with team structure, development process, product complexity, and size; some organizations benefit from combining tools. Tool listings and capabilities can change, so confirm current coverage against your own product before adopting a tool.
Bring appropriate expertise and user perspectives
Evaluation requires people who can interpret accessibility standards, inspect design and implementation, use relevant assistive technologies, and understand how people with disabilities interact with digital products. Involve people with disabilities where possible: their experience can reveal barriers that a scan or checklist may not surface. User evaluation contributes an important perspective, but it does not by itself establish WCAG conformance.
Document findings so teams can act on them
For each finding, capture enough context for another person to reproduce it and for the team to verify a fix:
- Product and version evaluated, scope, sample, and evaluation method.
- The relevant criterion or issue, where applicable, plus evidence and observed result.
- Steps, view or state needed to reproduce the barrier.
- Remediation owner, status, and retest outcome.
- What was not evaluated, including sampling choices and tool limitations.
WCAG-EM’s report tool helps structure and record evaluator input; it does not perform the checks. Make clear whether each item is a WCAG requirement, a test technique, a team practice, or a usability observation.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Prioritize fixes, retest, and make checks recurring
Connect findings to owners and remediation work, then retest corrected issues and add recurring checks to the normal product workflow. The prioritization method and any release gate are choices for the organization; the W3C materials cited here do not prescribe a universal severity formula or gate. Whatever approach you choose, document it and apply it consistently.

For accessibility evaluation, use the process above: a screenshot is visual evidence, not an accessibility test or conformance determination. If you need a clean capture to attach to a finding or review, ScreenshotNeo can return a screenshot or PDF from one request. Its screenshot capture is not a replacement for accessibility checks.
Example cURL request (see the ScreenshotNeo API documentation):
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webp
ScreenshotNeo accepts cookie or consent banners and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each step can be turned off. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed, and responses identify the page verdict and billing status in headers. Its MCP server provides screenshot, page-info, and PDF-capture tools for AI agents. The free plan includes 1,000 screenshots per month without a card; paid plans start at $5 for 3,000 shots.

What changed with WCAG-EM 2.0
W3C published WCAG-EM 2.0 as a Group Note on 23 July 2026. It broadens the earlier methodology’s website-and-web-page scope to apps and other digital products. The W3C overview page was updated on 12 August 2026. WCAG-EM remains a methodology for evaluating conformance to WCAG, not a new set of accessibility requirements.
