Section 508 and ADA Title II are not the same requirement.
| Topic | Section 508 | ADA Title II web rule |
|---|---|---|
| Who is covered | U.S. federal agencies and covered federal ICT procurement contexts | State and local government entities covered by ADA Title II |
| Technical framework | Revised 508 Standards, including WCAG 2.0 Level AA references for many ICT requirements | WCAG 2.1 Level AA, subject to rule provisions and exceptions |
| Timeline | In force | 2027 and 2028 compliance dates based on population and entity type |
| Typical audit use case | Federal procurement, vendor documentation, ACR support | State/local government websites, mobile apps and public-service workflows |
Procurement can blur the conversation because vendors may be asked for an Accessibility Conformance Report that includes Section 508 criteria. That does not make Section 508 identical to ADA Title II.
