Where the program stands
The W3C Accessibility Maturity Model measures an organization across seven dimensions and four levels: Inactive, Launch, Integrate and Optimize. It was published as a W3C Group Note on November 4, 2025, by the Accessible Platform Architectures Working Group.
It's a benchmark, not a legal standard. No regulation requires it, and the Note is endorsed by the working group that wrote it rather than by W3C as a whole. Its four level names match the Policy-Driven Adoption for Accessibility model that some state and local governments already use.
Without a dedicated team, the practice starts with two dimensions, because both cost little and change what everyone else does: Oversight and Culture, where the program gets an owner, a policy and a budget line, and Procurement, where accessibility requirements go into contracts so the next system arrives conformant. The practice's Accessibility Maturity Assessment scores each dimension with the evidence behind it.
