Essential Section 508 Testing Tools

Section 508 is an integral part of web accessibility – if you manage a website, Section 508 is something you need to be aware of.

Online accessibility goes beyond just web pages, which is where Section 508 comes into play.

Before we get into some of the 508 compliance tools you can use to test PDFs, word documents, web pages, and screen reader compatibility, let’s dive into a quick recap of the rehabilitation and how it applies to your business.

What Section 508 Means for Your Business

Section 508 of the Rehabilitation Act requires federal agencies to produce, maintain, and use Information and Communication Technology that’s accessible to everyone, including those living with disabilities.

This ensures that federal employees with disabilities are able to carry out their duties on accessible devices and equipment, engage in online training, and access internal websites. The same applies to anyone applying for a job with the federal government or anyone using an agency website to get information. 

Information and Communications Technology (ICT) refers to any systems or equipment used to generate, convert, or access data and general information.

Some examples include:
  1. Mobile devices
  2. Internet websites
  3. PDF documents
  4. Online training
  5. Webinars
  6. Remote access tools
  7. Support control centers
  8. Software and operating systems

Section 508 Testing Options

There are a few ways that you can test for 508 compliance, including:

Manual testing

This requires you to manually check any documents and web pages in a consistent and repeatable manner according to Section 508 requirements.

Automated testing

With the help of 508 tools, you can automatically test for compliance.

Hybrid testing

This is a combination of manual and automated testing. 

Since automated testing is the fastest and easiest way to achieve 508 compliance, we will be focusing on a range of tools that you can use.

PDF 508 Compliance Tools

If PDFs are available on your website or you send PDFs as a form of communication, they need to be accessible to those with disabilities.

PDFs should be able to be read aloud by screen readers and tabbed through using the tab key.

Adobe Acrobat Pro Accessibility Checker

Not only does Adobe Acrobat Pro check the accessibility of existing PDFs, but it also makes it that much easier to create accessible documents from scratch. The tool automates many tasks and provides you with instructions on how to manually fix PDFs that are currently inaccessible.

Developed by Freedom Scientific, JAWS (Job Access With Speech) can be used to test PDFs, ensuring they are accessible to the visually impaired. To achieve this, the tool uses Viz. Eloquence and Vocalizer Expressive, both of which are multilingual synthesizers. JAWS is compatible with Firefox, IE, Windows, and Microsoft Office. Testing PDFs with JAWS will immediately highlight any accessibility concerns.


Tingtun Checker

This might be one of the simpler tools, but it is useful for identifying PDF accessibility issues. Simply insert the URL to the PDF you want to check and Tingtun will do the rest.

Screen Reader 508 Compliance Tools

Millions of people are living with visual impairments, including complete blindness. Chances are, a visually impaired user will encounter your website and online content at some point, which means it should be compatible with screen readers.


Developed for Apple devices, VoiceOver can be used to test whether your website, app, and online content are compatible with screen readers. Simply install the tool on an iOS device and you will be able to test how well a screen reader explains your content. You can also test whether a user can utilize keyboard navigation to engage with your site and content.



aDesigner was created by Eclipse to help web designers create sites and applications that are accessible to all, including those who use screen readers. Along with testing how well screen readers interact with your content, aDesigner also checks the accessibility of Flash content and Open Document Format documents (ODF). The tool will provide you with a list of accessibility errors should they be present. 


Adobe Dreamweaver

Dreamweaver is specifically for developers who are building sites and applications with accessibility in mind. The platform offers screen reader and operating accessibility support, as well as keyboard navigation, everything you need to test a site for Section 508 compliance concerns.
