openpaymentsdata.cms.gov: Accessibility — week 2026-W26

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
1.4.8	WCAG 1.4.8	99	1
2.5.5	WCAG 2.5.5	99	1
4.1.2	Name, Role, Value (ARIA)	66	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.

Top 10 clustered component fixes for this week.

Description

All page content should be contained by landmarks. Detected by axe-core rule region on 206 of 237 scanned pages (618 instances).

Steps to reproduce

Open https://openpaymentsdata.cms.gov/about.
Locate the element: .ds-u-sm-margin-top--5
Confirm the axe-core finding for rule region.

Impact

Not captured by automated scan — requires manual testing.

Affected pages

…and more — all 206 pages (CSV).

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: Wrap all page content in landmarks (header, nav, main, footer) so users can navigate by region.

Drupal tip: Use Drupal's region system (header, navigation, main, sidebar, footer) and map each to an HTML5 landmark element in your theme's page.html.twig.

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): 668
Caught by both engines: 0 highest confidence
axe only: 206
Alfa only: 462

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