When beginning your Digital Accessibility journey, the amount of information can be overwhelming. So let's start with the basics, compliance standards and levels of compliance.
Note: This guide was originally published in February 2022 and has been comprehensively updated on October 18, 2025, with WCAG 2.2 requirements, legal enforcement data, and practical compliance guidance.
(https://www.w3.org/WAI/standards-guidelines/wcag/) (WCAG – pronounced wee-cag) is the worldwide best best practice for web accessibility. It is also the standard adopted by major international legislation including the United States’ Americans with Disabilities Act (ADA) and the European Union’s European Accessibility Act (EAA). WCAG provides a series of web accessibility guidelines published by the Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3).The guidelines, or “success criteria” outlined within WCAG describe how to make web content more accessible to people with disabilities.
📅 October 2025 Update: WCAG 2.2 & Legal Compliance Requirements

WCAG 2.2: 86 Success Criteria Across Three Levels
WCAG 2.2 released in October 2023 is the current standard with 9 new success criteria:
Breakdown by Level:
- Level A: 30 criteria (essential baseline)
- Level AA: 24 additional criteria (54 total - industry standard)
- Level AAA: 32 additional criteria (86 total - enhanced accessibility)
New in WCAG 2.2 (9 criteria):

- Applies to: Federal agencies, contractors, grant recipients
Which Level Should You Target? (2025 Decision Framework)
❌ Level A Alone - NOT RECOMMENDED
Why: Insufficient for legal compliance in any major jurisdiction
- No court or regulation accepts Level A as adequate
- Leaves critical barriers (color contrast, navigation consistency, error handling)
- Use only as interim step during remediation
✅ Level AA - RECOMMENDED (95% of organizations)
Choose Level AA if you:
- Serve customers in US, EU, Canada, UK, or other major markets
- Want to minimize legal risk and avoid lawsuits
- Need ADA, EAA, or Section 508 compliance
- Seek comprehensive accessibility for majority of users
Level AA provides:
- ✅ Legal compliance in US (ADA), EU (EAA), and most countries
- ✅ Accessibility for ~90% of users with disabilities
- ✅ Defense against accessibility lawsuits
- ✅ Competitive advantage and broader market reach
This is the right choice for: E-commerce, SaaS, corporate websites, educational institutions, healthcare providers
🎯 Level AAA - Selective Enhancement
Full AAA compliance: Often impractical for entire site
Consider AAA for:
- Critical workflows (checkout, account access, forms)
- Health, safety, or emergency information
- Government services and benefits
- Educational content
- Organizations with specific accessibility commitments
Practical approach: AA baseline + selective AAA for important content
2025 Enforcement Landscape

Within WCAG there are three levels of compliance Levels A, AA, and AAA. As such, compliance is categorized into three levels in order to meet the needs of different groups and different situations. Level A is the minimum level. Level AA includes all Level A and AA requirements. Many organizations strive to meet Level AA. Level AAA includes all Level A, AA, and AAA requirements. Let's dig a little deeper into each level.
Level A: Level A is considered the minimum level of compliance. At a high level, Level A compliance requirements prohibit elements that would make the website inaccessible for persons with disabilities. Essential Level AA requirements include: No keyboard traps; Navigable with a keyboard; Non-text content alternatives; Video captions; Meaning is not conveyed through shape, size, color etc. alone. Websites that do not meet at least Level A compliance can be extremely difficult for people with disabilities to use.
Level AA: Level AA is the compliance level that most organizations strive to meet. By following Level AA success criteria, your website will be usable and understandable for the majority of people with or without disabilities. Essential Level A requirements include: Color contrast is, in most instances, at least 4.5:1; Alt text or a similar solution is used for images that convey meaning; Navigation elements are consistent throughout the site; Form fields have accurate labels; Status updates can be conveyed through a screen reader; Headings are used in logical order.
Level AAA: Level AAA is the optimal compliance level which makes your site accessible to the maximum number of users, while making improvements to the user experience. Essential Level AAA requirements include: Sign language interpretation for audio or video content; Color contrast is at least 7:1 in most instances; Timing is not an essential part of any activity; Context-sensitive help is available. Although considered the optimal compliance level, it is cautioned that AAA may be difficult to achieve for an entire site, so you may want to focus on your audience’s specific needs for specific content.
It is important to note that compliance at higher levels indicates compliance at lower levels. For example, by complying to AA, a web page meets both the A and AA compliance levels.
