About the Client

A U.S.-based K–12 education solutions provider specializing in curriculum design and digital content development for early learning through secondary education. The organization collaborates with educators to create standards-aligned, engaging instructional materials that support diverse learning needs and empower teachers to deliver inclusive, high-quality classroom experiences.

Challenges They Faced

The organization encountered multiple challenges while attempting to make a large repository of educational PDFs accessible within a compressed timeline:
  • High-Volume Accessibility Requirements – Hundreds of PDF files containing tens of thousands of pages required remediation within a strict deadline.
  • Untagged and Unstructured Documents – Files lacked semantic tagging and logical reading order, preventing effective navigation by assistive technologies.
  • Complex Tables, Lists, and Mathematical Content – Educational materials included intricate structures requiring manual correction to ensure meaningful interpretation.
  • Missing Alternative Text for Images – Essential visuals lacked descriptive alt text, limiting access for learners using screen readers.
  • Non-Interactive Form Fields – Form-heavy documents required conversion into accessible, fillable formats with proper labeling and keyboard navigation.
  • Strict Compliance Requirements – All content needed to meet Section 508 and WCAG accessibility standards while maintaining instructional integrity.

Solutions We Offered

To address these challenges, a rapid, large-scale accessibility remediation initiative was implemented using a combination of automation, expert intervention, and rigorous quality assurance.
  • Rapid Team Mobilization and Parallel Workflows – A specialized accessibility team was assembled, and parallel workflows were implemented to meet the accelerated delivery timeline while maintaining quality standards.
  • Automated Preprocessing and Tagging Support – Automation tools were used to perform initial tagging and structural checks, enabling the team to focus manual efforts on complex remediation tasks.
  • Manual Semantic Tagging and Content Structuring – Accessibility experts applied semantic tags, corrected reading order, and ensured logical navigation across headings, tables, lists, and instructional content.
  • Alt Text Authoring for Educational Visuals – Meaningful alternative text was authored for essential images to ensure equitable access for learners using assistive technologies.
  • Accessible and Interactive Form Conversion – Form fields were tagged and converted into fully accessible, fillable formats with clear labels, tooltips, and keyboard navigation support.
  • Comprehensive Quality Assurance and Testing – Rigorous testing using screen readers and accessibility validation tools ensured compliance with WCAG standards and optimal usability.
