www.medicare.gov: Accessibility — week 2026-W31

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.

SC	Criterion	Pages	Rules
2.5.5	WCAG 2.5.5	486	1
1.4.8	WCAG 1.4.8	480	2
4.1.2	Name, Role, Value (ARIA)	419	2
1.4.6	WCAG 1.4.6	31	1
1.4.3	Contrast (Minimum)	9	1

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.

Design-system alignment (cms-ds / medicare). ds-c-fieldset: 49.7% of sampled rule findings · ds-c-alert: 0.4% of sampled rule findings

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.

Unique issues (rule × page): 2629
Caught by both engines: 0 highest confidence
axe only: 862
Alfa only: 1767

No issues were flagged by both engines on the same pages this week.
