Ensuring that digital content is accessible to everyone isn’t just a best practice—it’s a legal obligation for many U.S. organizations. Section 508 compliance refers to federal requirements that ensure websites, apps, and digital documents are usable by individuals with disabilities.
Whether you’re a government agency, contractor, or company that receives federal funding, understanding what is 508 compliance and how to test for it is essential. In this blog, we’ll cover what 508 compliance means, why it matters, and the steps you can take to evaluate your content through 508 testing.
What Is 508 Compliance?
Section 508 of the Rehabilitation Act requires federal agencies and any organizations that do business with them to ensure that their electronic and information technology (EIT) is accessible to people with disabilities.
Section 508 is closely aligned with the Web Content Accessibility Guidelines (WCAG), particularly WCAG 2.0 Level AA, which sets standards for things like text alternatives, keyboard navigation, and screen reader compatibility.
Who needs to comply?
- Federal government departments and agencies
- Contractors working with the federal government
- Educational institutions receiving federal funding
- Software and tech vendors providing products or services to the government
Why 508 Compliance Is Important
Legal Consequences
Failure to comply with Section 508 can result in lawsuits, penalties, loss of contracts, and damage to an organization’s public trust.
Ethical Responsibility
Accessibility isn’t just a legal checkbox—it’s about ensuring equal access to information and services for users with visual, auditory, cognitive, and motor impairments.
Making your content accessible also benefits:
- Older adults
- People with temporary injuries
- Users accessing content in non-ideal environments (e.g., poor lighting, noisy spaces)
Steps to Evaluate 508 Compliance
1. Conduct an Initial Audit
Review your website, app, or document against WCAG 2.0 AA standards to identify accessibility issues. A professional accessibility audit provides a clear picture of what needs fixing.
2. Use Automated Testing Tools
Tools like WAVE, Axe, and Google Lighthouse can quickly flag common accessibility issues, such as missing alt text or color contrast failures.
3. Perform Manual Testing
Automated tools only detect ~30–40% of issues. Manual testing includes:
- Navigating with a keyboard
- Checking logical reading order
- Verifying ARIA attributes and form labels
4. Involve Users with Disabilities
Real-world feedback from users who rely on assistive technologies (screen readers, voice commands, etc.) ensures your design is truly usable.
5. Document and Fix Issues
Create a prioritized list of issues and develop a remediation plan. Track changes and verify fixes with follow-up testing.

How to Test for Section 508 Compliance
Manual Testing Method:
This involves human testers evaluating digital content for accessibility based on user experience, WCAG criteria, and compatibility with assistive tech.
- Benefits: Catches real-world usability issues
- Limitations: Time-intensive and requires expertise
Automated Testing Method:
Tools scan content for detectable compliance issues (e.g., missing alt text, improper color contrast).
- Benefits: Fast, scalable
- Limitations: Doesn’t catch everything—must be paired with manual testing
What Are the Consequences of Not Complying with Section 508?
Failing to meet Section 508 standards can lead to:
- Legal actions and complaints filed under the Rehabilitation Act
- Loss of federal contracts or funding
- Public criticism or loss of trust from your audience
- Increased remediation costs later due to rushed or noncompliant development
Accessibility is not just about avoiding fines—it’s about demonstrating that your organization values equity, inclusion, and digital responsibility.
Conclusion
508 compliance is a critical part of accessible digital design. It’s a legal requirement for federal entities and their partners, but it’s also a standard that promotes usability for everyone.
By combining automated and manual testing, addressing WCAG issues, and involving real users, you can ensure your digital content is inclusive and legally sound.
