Unlike a public-facing accessibility statement, a digital accessibility policy is primarily an internal governance document. It typically names a target standard (commonly WCAG 2.1 or 2.2 AA), assigns ownership (a specific team or role, not “everyone”), defines when and how accessibility gets tested (at design review, before launch, and on a recurring audit cycle), and sets expectations for vendor and third-party tools.
Organizations without a written policy tend to see accessibility regress over time as content changes and staff turn over, because there’s no standing process forcing anyone to check.
