NB: The Theory of Change described in this document is a work in progress that has received only limited input and review from the community.
🎯 Outcome: Accessibility is consistently addressed and integrated during the design and development of web technologies, making it easy to build accessible experiences and hard to generate inaccessible ones
📈 Indicators
- Number of specified features that create accessibility footguns
Output: Web platform specifications include accessibility requirements validated through accessibility review processes
📈 Indicators
- Coverage of accessibility review of specified features before they get widely deployed
🎯 Outcome: Web content and applications are built using platform features and tools that support accessibility by default
📈 Indicators
- Share of Web content and applications that conform to WCAG AA
- Statistical measure of success in task completion on the Web for people with disabilities
Output: Web platform specifications include accessibility requirements validated through accessibility review processes
📈 Indicators
- Coverage of accessibility review of specified features before they get widely deployed
Output: Authoring tools, developer tools, frameworks and workflow support creation and validation of accessible content aligned with standards
📈 Indicators
- Share of widely used authoring and developer tools with built-in accessibility support
Output: UI Platform primitives provide built-in semantics, keyboard operability, and accessible interaction behaviors
📈 Indicators
- Coverage of deployed UI primitives that are confirmed to be accessible
🎯 Outcome: Assistive technologies provide reliable and consistent access to web content across platforms
📈 Indicators
- Share of Web features that can be demonstrated to be accessible across widely used assistive technologies
- Statistical measure of success in task completion on the Web for people with disabilities
Output: Specifications define consistent accessibility tree and platform API mappings across implementations
📈 Indicators
- Coverage of spec'd accessibility semantics to platform accessibility APIs
Output: Data about interoperable implementation of accessibility features
📈 Indicators
- Share of features whose accessible implementation status is comprehensively tracked
🎯 Outcome: Content and services providers adopt accessibility as a baseline requirement aligned with W3C accessibility standards
📈 Indicators
- Share of content and service providers that have a WCAG-based accessibility statement
- Percentage of decision makers in content and service providers that are aware of accessibility requirements
Output: Governments and regulators reference W3C accessibility standards in policy, procurement, and enforcement frameworks
📈 Indicators
- Number and share of accessibility policies that use WCAG as a core reference
Output: Accessibility standards are updated and aligned with evolving platform capabilities and implementation patterns
🎯 Outcome: Accessibility solutions reflect real user needs and are usable in practice across diverse disability contexts
📈 Indicators
- Statistical measure of success in task completion on the Web for people with disabilities
Output: Specifications and guidance reflect accessibility requirements validated through participation of people with disabilities and accessibility experts
📈 Indicators
- Number of persons with disabilities involved in validating accessibility requirements
🎯 Outcome: Web platform implementations demonstrate interoperable accessibility behavior across browsers, assistive technologies, and environments
📈 Indicators
- Share of features whose accessibility implementation is fully interoperable
- Number of features whose implementation is confirmed to be accessible across the most widely deployed implementations
Output: Test suites include accessibility tests that validate interoperable implementation
📈 Indicators
- Coverage of accessibility features in test suites
Output: Specifications define consistent accessibility tree and platform API mappings across implementations
📈 Indicators
- Coverage of spec'd accessibility semantics to platform accessibility APIs
Output: Data about interoperable implementation of accessibility features
📈 Indicators
- Share of features whose accessible implementation status is comprehensively tracked
