data.medicaid.gov: Accessibility — week 2026-W32

Automated Accessibility Conformance Report (OpenACR): Download ACR. Machine-readable; compatible with GSA OpenACR tooling. Automated tools find ~⅓ of real barriers — supplement with manual AT testing.

Training priorities

Top WCAG success criteria by pages affected this week. Use these to focus team training on the highest-impact issues.

Next 10 actions

Clusters are fingerprinted by normalized selector path + rule id + snippet shape. Rank score = (severity weight × pages affected) / distinct components for the rule. This supersedes the template threshold heuristic while still surfacing it as a validation signal.

Top 10 clustered component fixes for this week.

Bug reports

3 issue type(s) are shown by default out of 12 total. Prioritized by severity, key pages, WCAG level, and prevalence; use the toggle to show everything.

Overall severity mix: 2 serious, 10 moderate. By WCAG category: 5 WCAG 2.0 A, 1 WCAG 2.1 A, 2 WCAG 2.x AAA, 2 Best Practice, 2 Undetermined. Ordered by severity, key-page impact, WCAG level, and prevalence. Following accessibility bug-reporting best practices. Download: Markdown · JSON (full archive) · JSON (AI diagnostic) · CSV (all findings) · Priority pages CSV · Priority pages JSON.

Automated testing does not establish full WCAG conformance. Findings in the verification lane require manual testing before they are treated as confirmed failures.

Default view shows 3 prioritized issue type(s); 9 more are available if you switch to "Show everything".

1 finding(s) marked "possible duplicate" — Alfa and axe-core both flagged the same WCAG SC on overlapping pages. If they target the same element, the axe-core report is authoritative. Filter the CSV by possible_duplicate_of to see these. Two engines flagging the same barrier reduces the chance of a false positive.

Findings needing review

These findings need manual verification before they can be treated as confirmed failures. Obligation remains visible for each finding.

Unique accessibility issues (axe + Alfa consolidated)

axe and Alfa both implement W3C ACT rules, so the same issue is often caught by both. These are deduplicated by ACT rule and page, so a shared finding counts once (3516 raw engine findings → 3514 unique).

1 rule type(s) caught by both engines — highest confidence

Two independent ACT-rule implementations (Deque axe-core and Siteimprove Alfa) flagged the same issue on the same pages. Agreement between separate engines is strong evidence the barrier is real, not a single-tool false positive — the best place to start.
