External Resource Registry
Why This Registry Exists
Navigating the accessibility tool landscape can be overwhelming. This registry is maintained by the UA Digital Accessibility team to give you vetted, reliable recommendations — whether you're a developer running your first audit, a content creator checking contrast, or a leader evaluating enterprise tools. Every resource listed here has been reviewed for accuracy, reliability, and relevance to higher education.
How We Curate This Registry
Every resource in this registry is evaluated against four criteria before inclusion:
- Accuracy: Does it reflect current WCAG standards (2.1/2.2)?
- Reliability: Is it actively maintained with regular updates?
- Relevance: Does it serve UA’s specific needs in higher education?
- Accessibility: Is the resource itself accessible to people with disabilities?
Resources are reviewed quarterly. Items that become outdated, unmaintained, or inaccurate are removed. If you find a broken link or outdated information, please let us know.
Testing Tools
Automated testing catches roughly 30–40% of accessibility issues. The remaining 60–70% require manual testing with assistive technologies and human judgment. Use a combination of tools for the most complete coverage.
Automated Testing
These tools scan your content and flag potential WCAG violations. They’re fast and great for catching common issues, but they can’t evaluate things like whether alt text is meaningful or whether focus order is logical.
| Resource | Platform | What It Tests | Cost |
|---|---|---|---|
| axe DevTools | Chrome, Firefox extension | WCAG 2.1 AA violations in web pages. Industry standard with the lowest false-positive rate. | Free (Pro tier available) |
| WAVE | Browser extension, web service | Visual overlay showing errors, alerts, and structural elements directly on the page. Best for beginners. | Free |
| Accessibility Insights | Chrome extension, Windows, Android | Web (FastPass + full Assessment), Windows apps, Android apps. Includes guided manual checks. | Free |
| Pa11y | Command line, CI/CD | Headless accessibility testing for build pipelines. Supports WCAG 2.1 AA with HTML CodeSniffer or axe-core runners. | Free |
| Lighthouse | Chrome DevTools, CLI | Built into Chrome DevTools. Includes accessibility scoring alongside performance and SEO. Good starting point but less thorough than axe. | Free |
UA Recommendation: Start with axe DevTools for web page testing. It has the most reliable rule set and lowest false-positive rate in the industry. Add Accessibility Insights when you need guided manual testing steps.

Assistive Technologies
Understanding assistive technologies helps you build better products and test more effectively. These are the tools people with disabilities actually use to access your content.
Screen Readers
Screen readers convert on-screen content to synthesized speech or braille output. They’re essential testing tools for any accessibility practitioner.
| Screen Reader | Platform | Description | Cost | Testing Priority |
|---|---|---|---|---|
| NVDA | Windows | Free, open-source screen reader. Most popular free option; widely used in education and enterprise. Download and learn it — this is your primary testing tool on Windows. | Free | Primary (Windows) |
| JAWS | Windows | Industry-standard commercial screen reader. Dominant in enterprise and government environments. More features than NVDA but requires license. | Paid (UA may have licenses — check IT) | Secondary (Windows) |
| VoiceOver | macOS, iOS, iPadOS | Apple’s built-in screen reader. No installation needed — activate with Cmd+F5 (Mac) or triple-click Home/Side button (iOS). Essential for testing Apple platforms. | Built-in | Primary (Apple) |
| TalkBack | Android | Google’s built-in screen reader for Android devices. Activate in Settings → Accessibility. Essential for testing Android apps. | Built-in | Primary (Android) |
| Narrator | Windows | Microsoft’s built-in screen reader. Good for quick checks but less capable than NVDA/JAWS for comprehensive testing. | Built-in | Supplementary |
Testing Best Practice: The WebAIM Screen Reader Survey consistently shows that NVDA + Chrome and JAWS + Chrome are the most commonly used desktop combinations. For mobile, VoiceOver + Safari (iOS) and TalkBack + Chrome (Android) are dominant. Test with at least one desktop and one mobile combination.
Other Assistive Technologies
These technologies represent the broader spectrum of how people interact with digital content. Consider them during design and testing.
| Technology | What It Does | Testing Implications |
|---|---|---|
| Dragon NaturallySpeaking | Voice recognition for hands-free computer control and dictation | All interactive elements must have visible labels matching their accessible names |
| Switch Access | Navigate using one or more switches (buttons, sip-and-puff devices) | Focus order must be logical; all functionality reachable sequentially |
| ZoomText | Screen magnification with optional screen reader features | Content must reflow when zoomed; avoid fixed-size containers |
| Eye tracking | Control computer with eye movement | Touch targets must be large enough; dwell-click support important |
| Refreshable braille displays | Convert screen text to dynamic braille output | Proper semantic structure is critical; ARIA labels must be concise |
