Why this is broader than “certifications”

Public accessibility signals do not only come from certification programs. Some regions have official or third-party badges, while others mainly publish public-sector accessibility statements, monitoring records, or self-published accessibility pages.

This overview should only explain the source families. Certification-like sources have their own detail page, and accessibility statement sources should also have their own detail page so statement coverage is not hidden inside the parent page.

Current public data entry points

Current source summary

The table lists supported public data sources, source family, covered regions, and record counts in the current public summary. It is a source-level summary, not an accessibility search engine or compliance decision.

How Signal uses these sources

Signal does not need to send a user’s search results back to Accesserty for live lookup. The product strategy is to organize supported public records into indexes so matching can stay local as much as possible while keeping source limits visible.

1. Show Accesserty ALLY first because it is tied to verified domains and ongoing maintenance.
2. Then show stronger public records such as certifications, recognitions, badges, and awards.
3. If those are not found, show known accessibility statements.
4. When no supported record matches, show no badge and do not treat the gap as proof that the site is inaccessible.

What this source overview is not

This page explains source coverage. It is not a compliance promise.

• It is not an Accesserty-issued certification or endorsement.
• It is not a complete global database or website ranking.
• It cannot prove that a whole domain, every page, authenticated flow, or third-party service is accessible.
• An accessibility statement only indicates a public explanation channel; the content still needs to be checked for scope, updates, limits, and feedback paths.
