The information presented within this guide is aimed at website owners seeking to learn the ropes of web accessibility. Technical elements are described in layman’s terms, and, as a rule, all topics pertaining to the legalities of web accessibility are presented in as simplified a manner as possible. This guide has no legal bearing, and cannot be relied on in the case of litigation.
If you are a federal agency, a federally-funded organization, or a service provider to such an organization, you need to comply with Section 508 of the Rehabilitation Act. Under the law, your website, along with other information and communication technology (ICT) assets you own and display, must be accessible to people with disabilities.
To determine whether these assets comply with the law, you will need to test them. And, while a certain level of manual intervention will likely be necessary, a significant part of the testing process can be conducted through powerful, automated tools. Analyzing various areas of your website and online documents, these tools can provide you with critical information regarding their level of compliance, saving you time and money in the process.
However, knowing which tools you can and should rely on for an accurate assessment of your website and ICT isn’t always easy. Here at accessiBe, we want to make sure you can do just that.
That’s what this list is for.
In this guide, we explore the best tools for Section 508 compliance testing. We will explain which tools you should be using to test websites and which should be reserved for online documents. We will also highlight tools you can leverage to test other ICT assets to ensure they comply with Section 508 to the fullest extent.
Below are some of the best Section 508 testing tools available in 2024.
We’ve divided these tools into two categories:
- Section 508 website compliance testers

In the "When correcting spelling in Outlook" section, check the box for "Check Accessibility."
Testing websites and online documents using screen reader technology
To gain a proper understanding of the way certain visitors interact with your website and online documents, it is advisable to try to navigate through it using a screen reader. To that end, you can use the following tools:
NVDA
NVDA (NonVisual Desktop Access) is a free screen reader that allows you to examine how its users, primarily people with vision impairments, experience various aspects of your website and online documents. This is especially important when engaging with elements such as forms and dynamic content. If these aren’t configured correctly, the screen reader will either skip over them or describe them in an incomplete, confusing fashion. It is important to note that NVDA is only available for PCs running Microsoft Windows 7 SP1 and later.
JAWS
JAWS (Job Access With Speech) is the most popular screen reader in the world. It can be used on Windows OS, and paints a precise picture of the way people with vision impairments who rely on such tools experience your website. JAWS’ pricing packages begin at $95 a year.

Section 508 compliance: an overview
A key part of the Rehabilitation Act of 1973, Section 508 was enacted to provide members of the disability community with equal access to electronic and information technology developed, procured, maintained, or used by the federal government. Organizations that must comply with this law include federal agencies, organizations that accept federal funding, and service providers to such organizations.
As the original legislation did not account for web accessibility, Section 508 was amended in 2017 and websites and other web-based applications were added to the list of ICT that relevant bodies needed to make accessible.
In early 2018, lawmakers added a rule setting the Website Content Accessibility Guidelines (WCAG) 2.0 as the standard websites and web-based applications must adhere to under Section 508. Published by the World Wide Web Consortium (W3C), WCAG has become one of the most influential sets of guidelines pertaining to web accessibility.
Throughout the years, there have been a number of WCAG iterations:
- WCAG 2.0
- WCAG 2.1
- WCAG 2.2
Each WCAG version includes three levels of conformance: Level A being the most basic, Level AA the conformance level referenced by most international laws, and Level AAA, the highest level of conformance and hardest to achieve.
Under Section 508, websites and other web-based applications need to conform to WCAG 2.0 Level AA.
Automation vs. manual testing: what is the best approach to determine Section 508 compliance?
There are two common approaches toward testing websites and other web-based applications for Section 508 compliance:
- Manual testing
- Automated testing
Each method has its unique advantages:
Manual testing methodologies, although more labor-intensive and costly, provide valuable quantitative and qualitative data. Skilled testers thoroughly examine your ICT's features and technologies, assessing them against WCAG standards. This approach offers qualitative insights, uncovering any potential challenges your ICT may pose for individuals with specific disabilities. This information serves as a foundation for developing a plan to address these issues​.
Automated testing approaches are particularly efficient during the initial stages of compliance testing. Tools like accessScan can greatly enhance manual testing efforts by offering speed and cost-effectiveness. This approach proves especially beneficial for larger websites or when dealing with a high volume of ICTs that require compliance testing​​.
So, which approach is best?
As each testing method offers its own distinct advantages, the testing approach that yields optimal results is one that blends both automation and manual intervention.
Automated testing tools, like those we will present in the next section, can quickly identify many of the compliance issues existing within your website and web-based applications. With those flagged, you or, preferably, an expert service provider like accessServices, can further investigate these issues. Manual testers can also dig deeper into potential compliance issues that aren’t always evident and that automated testing solutions sometimes miss.
The importance of testing for Section 508 compliance
When engaging with websites, web-based applications and other digital environments, the disability community still faces significant barriers that do not exist for others. Complying with Section 508 will see you and your organization doing your part in ending this ongoing discrimination. Testing whether your website and other relevant ICT can be fully accessed by all users is the first step in this process. Based on the results yielded by the auditing process, you can understand the areas of your website and web-based applications that are inaccessible to people with disabilities. Then, you can begin taking the necessary steps to remediate them.
It is important to remember that Section 508 is a federal law. Those who fail to comply with it, if it applies to them, discriminate against the disability community and can face legal consequences, including potential lawsuits, as a result. The latter can have a significant negative impact on your brand and reputation.
Key takeaways
With a wide range of readily-available powerful tools, testing your website and web-based applications for Section 508 compliance is within reach. Once you gain a proper understanding of your website, online documents, and other ICT assets’ level of accessibility, you will be able to address and remediate compliance issues, if they exist.
