WCAG 3.2.2: On Input
WCAG 3.2.2 On Input requires that changing the setting of any user interface component does not automatically cause a change of context unless the user has been advised of that behavior beforehand. This protects users from disorienting, unexpected page changes triggered by form interactions.
WCAG 3.3.1: Error Identification
WCAG 3.3.1 requires that when an input error is automatically detected, the item in error is identified and the error is described to the user in text. This ensures users with disabilities can recognize, understand, and correct mistakes when filling out forms.
WCAG 3.3.2: Labels or Instructions
WCAG 3.3.2 requires that labels or instructions are provided when content requires user input, ensuring that all users — regardless of ability — can understand what is expected of them before submitting form data. Failing to label form fields is one of the most common and impactful accessibility barriers on the web.
WCAG 3.3.7: Redundant Entry
WCAG 3.3.7 requires that information users have already provided in a multi-step process is either auto-populated or made available for selection, so users never have to re-enter the same data twice. This prevents frustration and errors for users with cognitive, motor, or other disabilities.
WCAG 1.3.5: Identify Input Purpose
WCAG 1.3.5 requires that the purpose of each input field collecting personal information can be programmatically determined, enabling browsers and assistive technologies to autofill, label, or adapt fields automatically. This is essential for users with cognitive disabilities and motor impairments who benefit from reduced manual input.
WCAG 3.3.3: Error Suggestion
WCAG 3.3.3 requires that when an input error is automatically detected, the system must provide a text description suggesting how the user can correct the mistake — unless doing so would jeopardize security or purpose. This criterion is essential for users with cognitive disabilities, screen reader users, and anyone who struggles to understand vague or missing error guidance.
WCAG 3.3.4: Error Prevention (Legal, Financial, Data)
WCAG 3.3.4 requires that web submissions involving legal commitments, financial transactions, or sensitive data can be checked, corrected, or reversed before finalization. This protects all users — especially those with cognitive and motor disabilities — from irreversible, high-stakes mistakes.
WCAG 3.3.6: Error Prevention (All)
WCAG 3.3.6 requires that for any web page requiring user input, submissions are reversible, checked for errors with correction guidance, or confirmable before final submission. This AAA criterion extends 3.3.4 to all forms—not just legal or financial ones—protecting users from irreversible mistakes across every interaction.
