Accessibility that’s enforced on every publish

WCAG 2.1 AA isn’t a project you finish once. Sentra CMS checks every change before it goes live — so a site that’s fixed stays fixed.

Accessibility center: site score, pages passing, PDFs compliant and the enforcement rules

ADA Title II web rule: state and local governments, including school districts, must meet WCAG 2.1 AA — April 26, 2027 for 50,000+ people and April 26, 2028 for smaller governments and all special districts, after the Justice Department’s April 2026 extension. Dates could change again; the standard did not.

How enforcement works

Every change passes the AA gate

The same gate runs for editors, the API, the AI assistant and imported templates.

  1. Editor

    Edit

    An editor changes a page, uploads a PDF or adds a widget.

  2. Automatic

    AA gate

    WCAG 2.1 AA checks run automatically. Problems are explained with a fix.

    Blocks failures
  3. Your workflow

    Approve

    The department head, then the web admin, approve — or publish directly if allowed.

  4. Live

    Publish

    The page goes live and is committed to your repository.

  5. Every night

    Nightly scan

    Every published page is rescanned; your score and report update.

Questions

Is WCAG 2.1 AA the right standard?

It’s the standard named in the U.S. Department of Justice’s 2024 ADA Title II rule for state and local government websites and mobile apps.

Can an admin turn the checks off?

No. Enforcement is locked on for every site. Warnings can be acknowledged; blocking problems must be fixed.

Does this replace a manual audit?

No automated tool finds every barrier. Sentra CMS blocks what machines find reliably; we recommend a keyboard and screen reader review of key pages, included in migrations.

What about our existing PDFs?

Every document is checked. Failing ones are held in draft until they’re remediated or converted to a web page.

Do you use an accessibility overlay widget?

No. Sentra CMS fixes accessibility at the source — in the content, templates and documents. Overlay widgets don’t make a site conform; in 2025 the U.S. Federal Trade Commission ordered one overlay vendor, accessiBe, to stop claiming its product could make sites WCAG-compliant (summary).
