According to the UK's Office of Campus Accessibility and ADA, all digital resources must comply with the global standard Web Content Accessibility Guidelines (WCAG) version 2.1 level AA by April 24, 2026. Web content (including digital documents like PDF and presentations) that students, patients or the public have access to must be accessible.
It is the responsibility of the investigator to ensure participant recruitment materials meet accessibility requirements before they are submitted for Public Relations Review (PRR).
For investigators using Participant Recruitment Services (PRS) to create research recruitment materials, the PRS team will ensure all ADA requirements are met, before submitting them for Public Relations Review on your behalf. See FAQ 6 for more information.
Materials that do not meet accessibility requirements will be returned to investigators to update. Please make these updates in your original files, so when you edit those files in the future, you have taken care of common issues with alternative text for images/QR codes, document titles, etc.
General guidelines:
- Provide alternative text for non-text elements
- Alternative text: Commonly known as alt text, this is descriptive text that conveys the meaning of an image in digital content.
- Images: Add descriptive alt text to necessary images, charts and graphics.
- Decorative Elements: Mark purely decorative images so they are ignored by assistive technologies (i.e. backgrounds).
- See Section 508 guidance on alt text.
- Use proper document structure
- Headings: Utilize built-in heading styles to create a logical hierarchy, aiding navigation for screen readers.
- Lists: Employ standard list formatting for ordered and unordered lists.
- Tables: Use tables to present data, not for layout purposes, and include clear headers.
- Ensure proper reading order
- Verify content flows in a logical reading order, especially in PDFs, to ensure it is read correctly by screen readers.
- Use descriptive hyperlinks
- Write meaningful link text clearly indicating the destination or purpose.
- Instead of link text that says “click here,” use “Visit our site for the full details of this research study.”
- Maintain accessibility during file conversion
- When converting documents to PDF, ensure accessibility features (like tags and alt text) are preserved. Use the “Save As” or “Export” functions with accessibility options enabled.
- Properly title your PDFs. A PDF’s internal title (metadata) often differs from its filename because it is set during document creation (e.g., in Word) and does not update when the file is renamed. Accessibility tools identify the file by this title. To change the title, select File/Properties/Description in Adobe Acrobat.
- Open PDF in Adobe Acrobat and use the “check for accessibility” option to verify that your PDF meets accessibility requirements.
For more details and links to specific guidance for Microsoft, Google and Adobe Acrobat, review UK’s “Creating Accessible Documents” guidance.
QR codes
While Quick Response (QR) codes offer a convenient link to information, users with disabilities may need alternative ways to access the same content. Provide a text alternative or URL link adjacent to the QR code.
Provide appropriate alt text for the QR code describing where the QR code link takes you/for what purpose.
Alt text examples:
- “QR code links to the research study details webpage.”
- “QR code links to research study sign-up form.”
Social Media
Providing alt text for social media posts, including images, happens at the point those resources are uploaded. Please refer to accessibility guidance for the social media tool you use to post.
Canva
Templates and resources for participant recruitment advertising will be made available through Canva shortly. A step-by-step deep dive into the accessibility process is available on Canva’s website.
Users can also run their own accessibility checks. In Editor mode, Select File/Accessibility/Check Design Accessibility. Canva will evaluate your design based on accessibility criteria and return suggestions for improvement.
