The W3C published a new WCAG 3.0 Working Draft on March 3, 2026. The Accessibility Guidelines Working Group expects to publish a projected timeline by April 2026, but the final standard is not expected before 2028 at the earliest.
This is a working draft, not a recommendation. No regulation references it. No procurement requirement cites it. Do not restructure your compliance program around it.
That said, the direction matters if you are making long-term accessibility investments.
What is changing
WCAG 3.0 proposes fundamental structural changes to how accessibility conformance works:
- New conformance model. The A/AA/AAA tier system is replaced with Bronze/Silver/Gold levels. The Bronze level is designed to be roughly equivalent to current WCAG 2.x AA.
- Outcomes-based approach. Instead of binary pass/fail on individual success criteria, WCAG 3.0 moves toward scoring how well outcomes are met. A site could partially meet an outcome rather than just passing or failing.
- Broader scope. WCAG 3.0 covers web content, apps, tools, and emerging technologies. The current 2.x standard is primarily web-focused.
- New contrast model. The APCA (Accessible Perceptual Contrast Algorithm) replaces the current luminance contrast ratio, aiming for more perceptually accurate contrast evaluation.
What it does not change right now
Every current compliance obligation -- ADA Title II, Section 508, EAA -- references WCAG 2.1 or 2.2. That will not change until WCAG 3.0 is finalized, adopted by W3C as a recommendation, and then referenced by regulatory bodies. That process takes years.
Organizations should continue targeting WCAG 2.1 AA for current deadlines and WCAG 2.2 AA for forward planning.
Why it matters anyway
The shift from binary pass/fail to outcomes-based scoring will change how compliance tools work. Scanners, audit frameworks, and reporting will need to adapt. Organizations that understand the direction can make architecture decisions today that will not need to be reworked later.
The APCA contrast model is also worth watching. It handles light text on dark backgrounds and colored text significantly better than the current 2.x contrast ratio. Some designers are already using APCA informally alongside the current standard.
WCAG 3.0 is not actionable today. But it is a signal of where the industry is headed, and organizations making multi-year accessibility investments should factor that direction into their planning.
