Introduction to Accessibility Checkers

Accessibility checkers are essential tools that help ensure digital content can be accessed and understood by all users. They scan documents, presentations, PDFs, and online materials for potential accessibility barriers, such as missing alternative text, low color contrast, or improper heading structures, and provide guidance on how to fix them. Using accessibility checkers is an important step in creating inclusive learning and working environments, where everyone can engage fully with shared materials.

Most major platforms include built-in accessibility checkers or integrated tools to support this process. Microsoft Office applications (such as Word, PowerPoint, and Excel) feature an Accessibility Checker that reviews content for issues and offers step-by-step instructions for improvement. Grackle for Google Workspace provides similar functionality for Docs, Sheets, and Slides, helping users identify and correct accessibility errors before sharing or publishing. Adobe Acrobat’s Accessibility Checker analyzes PDFs, flagging elements like untagged content, reading order problems, and missing document structure, which are key features for screen reader compatibility. In our learning management system, Canvas includes an Accessibility Checker within the Rich Content Editor that helps instructors identify and resolve issues directly in course materials. Additionally, MCCCD has purchased Panorama to aid in identifying and resolving accessibility issues.

By routinely using these tools, content creators uphold accessibility standards and demonstrate a commitment to access, compliance with legal requirements such as the Americans with Disabilities Act (ADA), and Section 508 of the Rehabilitation Act. Accessibility checkers not only improve usability for individuals with disabilities but also enhance the overall clarity, structure, and professionalism of digital content for all users.
