Accessibility Heuristic Evaluation

This method involves systematically evaluating a digital service against a set of established accessibility heuristics (e.g., WCAG). It helps identify potential accessibility barriers and prioritize areas for improvement to ensure the service is usable by people with disabilities. This method is crucial for public sector organizations due to legal requirements and ethical considerations of serving all citizens.

What participants gain

  • Participants will be able to identify common accessibility barriers in digital services.
  • Participants will be able to apply accessibility heuristics to evaluate a digital service.
  • Participants will be able to prioritize accessibility issues based on impact and severity.
  • Participants will be able to generate actionable recommendations for improving accessibility.

Materials needed

  • Printed copies of the digital service's interface or a live website.
  • Copies of WCAG guidelines or a simplified checklist.
  • Pens and paper for note-taking.
  • Whiteboard or flip chart for capturing findings.
  • Timer.

How to run Accessibility Heuristic Evaluation, step by step

  1. Introduction (5 min): Explain the purpose of the heuristic evaluation and the importance of accessibility.
  2. Review WCAG guidelines (10 min): Briefly review the relevant accessibility guidelines and principles.
  3. Individual evaluation (20 min): Participants individually evaluate the digital service against the heuristics, noting any barriers.
  4. Group discussion (20 min): Participants share their findings and discuss the severity and impact of each barrier.
  5. Prioritization (5 min): The group prioritizes the accessibility issues based on their impact and severity.
  6. Action (5 min): Assign owners to address findings.
  7. Check (2 min): Confirm who is doing what by when.
  8. Connect (2 min): Summarize findings and transition to next activity.

Facilitator tips

  • Familiarize yourself with WCAG guidelines before the session.
  • Provide clear examples of accessibility barriers to participants.
  • Encourage participants to be specific and provide actionable recommendations.
  • Use a collaborative online document to capture findings.
  • Emphasize the importance of empathy in accessibility evaluation.

Common challenges

  • Participants unfamiliar with accessibility guidelines: Provide a brief overview of WCAG and common accessibility principles.
  • Subjectivity in evaluating heuristics: Use clear examples and discuss different interpretations.
  • Focusing on minor issues and missing major barriers: Encourage participants to prioritize based on impact and severity.
  • Lack of actionable recommendations: Prompt participants to suggest concrete solutions for each barrier.

Running it virtually

Use a shared online document or spreadsheet for participants to record their findings. Facilitate a virtual discussion to consolidate and prioritize accessibility issues using screen sharing and annotation features.

Expected results

A prioritized list of accessibility barriers and actionable recommendations for improvement. Increased awareness and understanding of accessibility principles among participants.
