Web Content Accessibility Guidelines (WCAG) 2.0 and 2.1 Services

TestPros understands that Web Content Accessibility Guidelines (WCAG) compliance is based on the premise that Software, Hardware and Document accessibility is part of each IT requirement, and should be addressed up front as part of the system development life cycle. We conduct Accessibility Assessments to test for Software, Hardware, and Document accessibility compliance early in the system development life-cycle to promote better planning, and to better avoid expensive rework later.

We also understand that compliance assessments are based on testing to standards, not any specific set of accessibility testing tools, and we work with our client’s to conduct Accessibility Assessments using evaluation procedures that address the applicable standards and guidelines such as the Americans with Disabilities Act (ADA), related W3C Web Content Accessibility Guidelines (WCAG) 2.1 digital accessibility (ISO/IEC 40500), Section 508, EN 301 549, Accessibility for Ontarians with Disabilities Act (AODA), EPUB (ISO/IEC TS 30135), ISO/IEC 40500:2012, and other applicable accessibility standards and guidelines independent of development platform or testing tools.


In general, compliance assessment testing with assistive technologies or accessibility test tool software alone does not provide a complete evaluation,and we use manual testing methods to conduct a full assessment. TestPros tests to the standard, not the tools, using an best-practice approach defined by the Department of Homeland Security and their Trusted tester program. Where applicable, TestPros aligns with Section 508 2.0, W3C WCAG 2.1, EN 301 549, AODA, the A11Y Project, DHS OAST, and/or client-approved compliance test processes, leveraging extensive experience with both assistive technologies and providing Disabled User Acceptance Testing as appropriate. In addition to identifying WCAG and/or Section 508 Software, Hardware, and Document Accessibility compliance issues, we work with the client or integrator development team to suggest remediation fixes for software applications and web content accessibility issues.

WCAG / Section 508 / EN 301 549 / AODA  / EPUB Compliance

We are expert in a multi-step approach to accessibility that includes the following:

  • Project Assessments
  • Training
  • Testing
  • Compliance Documentation, Certification & Support
  • Remediation of custom and commercial-off-the-shelf (COTS) software source code
  • Development and remediation of custom WCAG / Section 508 compliance technologies

Usability and Accessibility Testing

We deliver testing focused on measuring application design factors such as ease-of-navigation, feature – function and error control, consistency, feedback, performance, visual clarity, intuitiveness, and accessibility. High quality usability is a key factor in customer satisfaction, user acceptance and is critical in the launch of a successful software application.

  • Identify usability and human factors issues
  • Identify WCAG / Section 508 / AODA Accessibility Compliance issues
  • Assessments conducted via trained Accessibility and Usability Engineers, and user groups comprised of users with various experience levels
  • Delineation of testing procedures and user participant scripts
  • Complete test result reports

Document WCAG / Section 508 / EPUB Accessibility Compliance Assessment

  • We conduct all the applicable tests (WCAG 2.1 Levels A, AA, AAA or Section 508), then identify and suggest accessibility fixes for MS Word, PDF, and other documents
  • As an option, we can apply the fixes to your documents in order to bring it into full compliance with the Section 508 standard

Product WCAG/Section 508/ADA Accessibility Compliance Assessment

  • We conduct all the applicable tests, then identify and suggest WCAG/Section 508 fixes for software applications and web content
  • As an option, we can apply the “remediation” fixes to your software in order to bring it into full compliance with the Section 508 standard
  • Authorization to use the “TestPros Tested – 508 Compliance” logo (the Terms and Conditions of the 508 Compliance TestPros Tested Logo Agreement)
  • We provide complete test results reports used for VPAT / GPAT /AODA statements

Mobile WCAG / Section 508 / ADA Testing

TestPros performs accessibility testing for mobile devices, testing to the standard as with browser-based content and applications.

  • We use the WCAG 2.1 and/or Section 508 accessibility guidelines that apply to the app and documentation
  • As the DHS mobile accessibility guidelines mature to include a comprehensive approach, we also use the Veterans Administration ( supplemental guidelines for 508 accessibility on mobile devices
  • We conduct preliminary responsive web design testing as a best practice, to ensure accessibility features and controls are “baked-in”
  • We use assistive technologies for mobile include VoiceOver for iOS and TalkBack for Android

EPUB Support

Accessibility for an EPUB publication (A collection of one or more Renditions that represents a single intellectual or artistic work such as an ebook) goes a step beyond WCAG 2.0 compliance, requiring discovery metadata. TestPros verifies that EPUB publications 1) meet the requirements for Discoverable EPUB Publications, 2) meet the accessibility requirements for WCAG 2.0, meets the specific accessibility requirements for EPUB Publications defined in the current version of EPUB Requirements, and includes accessibility conformance metadata as defined in EPUB Conformance Reporting.

Ongoing Monitoring

While websites, software applications, mobile apps, and documents should undergo accessibility assessments before launching or any significant redesign, it is important to remember that content and applications are subject to constant changes.  For example, some websites have multiple content editors and this increases the risk of inadvertent accessibility issues creeping back into the software. It is therefore very important to monitor for continued accessibility compliance at specific intervals.

TestPros can assist with this ongoing monitoring by implementing monitoring tools and processes to help check on accessibility at certain intervals.  This can be a valuable resource in ensuring accessibility of your content, finding broken links, and other quality related issues.
