data.healthcare.gov: Accessibility — week 2026-W24

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
1.4.6	WCAG 1.4.6	836	1
1.4.8	WCAG 1.4.8	836	1
2.5.5	WCAG 2.5.5	836	1
4.1.2	Name, Role, Value (ARIA)	771	3
2.5.3	WCAG 2.5.3	5	1

Bug reports

4 issue type(s) are shown by default out of 21 total. Prioritized by severity, key pages, WCAG level, and prevalence; use the toggle to show everything.

Overall severity mix: 3 serious, 17 moderate, 1 minor. By WCAG category: 5 WCAG 2.0 A, 1 WCAG 2.0 AA, 1 WCAG 2.1 A, 1 WCAG 2.2 AA, 3 WCAG 2.x AAA, 4 Best Practice, 6 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 4 prioritized issue type(s); 17 more are available if you switch to "Show everything".

2 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 (3327 raw engine findings → 3326 unique).

Unique issues (rule × page): 3326
Caught by both engines: 1 highest confidence
axe only: 18
Alfa only: 3307

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.
