Then prioritize the barriers that block important user journeys, assign an owner and retest condition, and report exactly what was—and was not—evaluated. Automated tools help find candidates; they cannot determine accessibility on their own.
Why accessibility backlogs become noisy
A large finding count is not, by itself, a reliable measure of how inaccessible a product is or how much work it needs. Backlogs can mix potential tool errors, repeated symptoms from a shared template, findings from different releases or scopes, and reports that lack the context needed to reproduce or fix them. Some findings that look alike may still affect different user journeys or require different fixes, so verify before consolidating.

W3C’s guidance is direct: “Tools cannot check all accessibility aspects automatically. Human judgement is required.” Automated results are useful signals, not verdicts. W3C guidance on selecting evaluation tools also notes that tools may produce false or misleading results and cannot determine accessibility on their own.

Set a clear scope before you scan
Agree on the evaluation target and its boundaries before findings enter a shared backlog. WCAG-EM 2 describes a process of defining scope, exploring the product, selecting a representative sample, evaluating it, and reporting results. Its methodology covers websites, apps, and other digital products; it helps evaluate conformance to WCAG but does not add requirements to WCAG. See the WCAG-EM overview and the WCAG-EM 2.0 publication.
#1 Best Overall
For each evaluation, record:
- Product, release or version, and evaluation purpose.
- WCAG version and target conformance level.
- Evaluation dates, environments, technologies, and relevant account or permission state.
- Pages or views covered, the important user journeys included, and any exclusions.
- Tools and versions used, plus the manual-review methods.
This intake contract prevents results from unrelated products, releases, or coverage from being merged as if they described the same evaluation.
Build a representative map of the product
Before treating every URL or scanner result as a separate task, identify the structures users encounter: page templates, shared components, content types, dynamic states, and key flows such as signing in, searching, or completing a purchase. Use automated checks where they add breadth, and select a representative sample for hands-on evaluation—especially important templates and flows.
Sampling is a way to organize evaluation, not permission to overstate coverage. WCAG-EM 2 cautions that reviewing a subset does not establish that an entire website conforms: untested pages may still contain errors. State which pages, views, and flows were examined and avoid a whole-product conformance claim based only on a sample. WCAG-EM 2.0

Normalize and verify each candidate finding
Give every candidate enough information to reproduce and assess it. A practical intake record includes the affected page or view and element, steps to reproduce, observed user impact, relevant WCAG success criterion, test method and tool version, and supporting evidence such as a screenshot or short recording. This is an operating recommendation; the W3C accessibility evaluation report template asks reports to document scope, tools, processes, detailed results, and recommended actions.
- Reproduce the result. Check the same content, state, and interaction where the finding occurred.
- Assess it in context. A reviewer with relevant accessibility knowledge determines whether it creates a real barrier, reflects a tool limitation, or needs more information.
- Record the decision and evidence. Keep the reason for confirming, changing, or closing the finding with the record.
Do not close or downgrade an item merely because a scanner labels it a possible false positive. W3C’s Understanding Conformance puts the distinction plainly: “Testing the success criteria would involve a combination of automated testing and human evaluation.”
Cluster findings only when the cause is shared
After verification, group records when they have the same underlying cause, affected component or template, and remediation path. Keep the affected routes, user impact, and test evidence visible beneath the parent issue. Retest the shared component and representative instances after a fix.
Keep findings separate when the apparent duplicates produce different barriers, occur in meaningfully different contexts, or need distinct fixes. Clustering is a practical backlog method, not a prescribed W3C deduplication algorithm; WCAG-EM and W3C reporting guidance support exploring product structure, sampling, and documenting findings, but do not specify a universal way to merge records. WCAG-EM overview · Report template
Prioritize verified barriers without inventing a score
W3C’s reviewed materials call for prioritization and recommended actions, but do not define a universal numeric severity formula. Use a transparent team triage model instead. Rank confirmed barriers by:
- Task importance: Does the barrier block or significantly impede a high-value user journey?
- Impact: How serious is the impediment for the people encountering it?
- Breadth: How many templates, views, or experiences are affected?
- Recurrence: Does it appear across repeated states or interactions?
- Fix leverage: Can one shared change remove several verified occurrences?
For each prioritized item, name an owner, the evidence behind the decision, and the condition for retesting. This makes trade-offs reviewable and helps prevent a raw count—or an unsupported severity label—from deciding the work. W3C identifies weak prioritization and poor integration across design, development, and maintenance as contributors to late-stage testing challenges. W3C conformance and testing challenges
Fix at the source, retest, and keep the record current
When several validated occurrences come from one component, template, or authoring process, fix that shared cause where appropriate. Retest the component and representative affected pages or flows; record the retest date, method, result, and any remaining contexts. If the issue returns, retain that history rather than silently reopening an indistinguishable record.
Bring checks earlier into design and development so teams can find barriers throughout the product lifecycle instead of waiting for a final audit. Reports should show scope, exact review dates, tools and versions, manual methods, findings, recommended priorities, and a monitoring plan. Make sample limits explicit and schedule monitoring in proportion to how often the product changes. W3C report template
Choose evaluation tools for the job
Tool choice should follow the product and workflow, not a headline feature list. W3C recommends considering:
Rank #4
- Whether the tool supports the content types you need to evaluate, such as websites, apps, or documents.
- Which standards and test rules it supports, and whether it automates checks or assists manual evaluation.
- Its scope: a single page, related pages, or broader coverage.
- Whether it can reach authenticated and dynamic states in your product.
- How results are reported and presented in context, and whether the tool itself is accessible.
- How it fits the team’s implementation workflow and what licensing applies.
Regardless of the tool, automated coverage is incomplete and human judgment remains necessary. For more consistent interpretation across different test methods, W3C’s Accessibility Conformance Testing (ACT) approach covers automated, semi-automated, and manual testing. The W3C overview reports that the ACT Rules Community Group developed over 50 rules; that figure describes the group’s work, not a claim that every rule is an approved W3C Recommendation. The overview states that ACT Rules Format 1.1 was published in February 2026. W3C ACT overview

Frequently Asked Questions
Does WCAG-EM 2 add new WCAG requirements?
No. WCAG-EM is a methodology for evaluating how well a digital product conforms to WCAG; it does not add requirements to WCAG.
Does a clean automated scan prove a product is accessible?
No. Automated tools cannot check every accessibility aspect or determine accessibility on their own; human evaluation is also needed.
Can a representative sample establish that an entire site conforms?
No. A sample can inform evaluation, but WCAG-EM 2 cautions that untested pages may still contain errors.
