In 2026, digital textbooks have become an essential part of the infrastructure in higher education, with the global market projected to reach $29.5 billion by 2027, at a 17% annual growth rate. Educational institutions are not just easing coursework distribution; they’re revolutionising access to education for all students, including the 7.3 million K-12 students and millions of college students with disabilities in the United States alone.
However, true digital transformation requires more than digitisation; it demands accessibility. With the ADA Title II compliance deadline of April 26, 2027, for large institutions, and WCAG 2.2 now recognised as the international standard (ISO/IEC 40500:2025), accessible digital textbooks are no longer optional; they’re a legal and educational imperative.
The Need For Accessibility In Higher Education
The challenge for publishers arises when they need to make sure that the digital textbooks provided by them are accessible to visually impaired students. The increased utilization of images published in higher education course material provides publishers with the important task of ensuring that each image is readable by assistive technology utilized by the visually impaired, such as screen readers.
Alt-text or alt descriptions are tagged in images and used to describe images, this text can be read by assistive technology used by the visually impaired, enabling them to understand and navigate digital textbooks easily. Due to the high volume of coursework that needs to be published, the need of the hour for publishers is a solution to generate alt-text in a way that is less time-consuming and highly accurate.
Today’s accessibility landscape has evolved far beyond basic alt-text. Students with disabilities represent nearly 20% of domestic students in many institutions (a 46% increase over five years in the UK), and they require diverse accommodations: real-time captions for deaf and hard-of-hearing students, adjustable font sizes and color contrast for those with low vision, keyboard navigation for students with motor impairments, simplified language and structured content for cognitive disabilities, and text-to-speech for dyslexic learners. The challenge for publishers is creating textbooks that meet WCAG 2.2’s 9 new success criteria while remaining engaging, cost-effective, and pedagogically sound.
The Benefits Of Providing Accessible Digital Textbooks
1. Inclusive Environment
By providing coursework that can be accessed by visually impaired users with the help of assistive technology such as screen readers, educational institutions create an inclusive learning environment enriched with equal opportunities.
2. Improves Learning Experience
By providing digital accessibility in higher education, educational institutions meet the needs of visually impaired students and by filling the gap in accessibility in higher education, the learning experience of visually impaired students is greatly improved.
3. Meet Compliance
By creating accessible learning material, educational institutions meet multiple critical compliance standards:
- WCAG 2.2 Level AA: Now the international standard (ISO/IEC 40500:2025), featuring 9 new success criteria addressing cognitive disabilities, mobile usability, and authentication
- ADA Title II: Compliance deadline of April 26, 2027, for large public institutions (50,000+ population)
- Section 508: Federal accessibility requirements for institutions receiving federal funding
- European Accessibility Act (EAA): For institutions with international reach
- Universal Design for Learning (UDL): Pedagogical framework for inclusive education
Meeting these standards not only avoids legal risk with ADA digital accessibility lawsuits exceeding 8,600 annually, but also demonstrates institutional commitment to equity and inclusion.

How to Create Accessible Digital Textbooks in Higher Education
Creating accessible digital textbooks is a foundational commitment to ensuring every student, regardless of ability, can fully participate in academic life. Educational institutions are increasingly providing digital textbooks so students can access course material anywhere and anytime, but this convenience only delivers equal value when content is built with accessibility at its core.
1. Choose the Right File Format
The format you publish in determines how accessible your textbook can become. EPUB 3 is the gold standard; it supports semantic structure, logical reading order, and is natively compatible with most screen readers. Accessible PDF (PDF/UA) is widely used in academia but must be properly tagged from the start, not remediated after the fact. The key principle: accessibility must be embedded into the production pipeline from day one, not bolted on afterward.
2. Structure Content with Semantic Markup
Accessible textbooks require a clear, logical document structure that assistive technologies can interpret. Use a proper heading hierarchy (H1, H2, H3) that reflects the actual organization of content, not just visual styling. Ensure a logical reading order for multi-column layouts and sidebars. Mark up lists and tables correctly. Tables must include proper header rows, and complex merged-cell tables should be restructured or avoided entirely.
3. Provide Meaningful Alt Text for Every Image
The increased utilization of images in higher education course material creates the important task of ensuring that each image is readable by assistive technology. Alt text is tagged to images and enables visually impaired students to understand and navigate digital textbooks easily.
Effective alt text describes the informational content of an image, not just its appearance. Complex visuals like charts and diagrams need long descriptions that summarize the data or concept being conveyed. Decorative images should carry null alt text so screen readers skip them. Due to the high volume of coursework that needs to be published, publishers increasingly need solutions to generate alt text in a way that is less time-consuming and highly accurate, making AI-powered alt text generation tools increasingly essential at scale.

4. Make Multimedia Accessible
Video content must include accurate synchronized captions. Auto-generated captions are rarely sufficient for technical academic material. Videos with visual-only information (lab demonstrations, annotated diagrams) require audio descriptions. Full text transcripts should accompany all audio and video. Interactive elements like simulations and quizzes must be fully keyboard-navigable for users who cannot operate a mouse.
5. Handle STEM Content with Proper Standards
Mathematical equations rendered as images are completely inaccessible to screen readers. Use MathML to encode equations so assistive technologies can read them aloud or output them to Braille displays. For chemistry and scientific diagrams, ensure structural descriptions accompany all complex visuals.
6. Apply Accessible Visual Design
Text must meet WCAG 2.1 contrast ratios (at least 4.5:1 for normal text). Never use color as the only way to convey information; always supplement with labels, patterns, or other differentiators. Use legible typefaces with adequate line spacing, and ensure layouts reflow properly across different screen sizes and zoom levels.
7. Meet Compliance Standards
By creating accessible learning material for visually impaired students, educational institutions meet Section 508 compliance standards for higher education. Publishers should also align with WCAG 2.1 AA, EPUB Accessibility 1.1, and, where applicable, the ADA Title II requirements governing equal access to educational programs.
8. Build Accessibility into the Workflow
Accessibility must be part of every production stage, not a final-stage fix. By automating the process of adding alt text, publishers can greatly increase their productivity and ensure they meet deadlines while saving on time and costs. Automated checkers (PAC for PDF, Ace by DAISY for EPUB) should be mandatory gates before publication, followed by human expert review, since automated tools typically catch only 30–40% of real-world accessibility issues.
By following these eight steps spanning format, structure, image accessibility, multimedia, STEM content, visual design, compliance, and workflow, higher education publishers and institutions can deliver digital textbooks that are genuinely accessible to every student.
