ACT Rules

A set of standardized, machine-readable test rules developed by the W3C that provide specific, objective criteria for evaluating whether web content meets accessibility requirements like WCAG success criteria. ACT Rules aim to reduce inconsistency between different automated accessibility evaluation tools by defining precise testing procedures with expected outcomes. Each rule specifies what is being tested, the applicability conditions, and the expected results, enabling different tools to produce consistent and comparable results when assessing the same content.
