Each year, Global Accessibility Awareness Day (May 15) calls attention to an essential aspect of modern digital services: accessibility. It focuses on the premise that accessibility is not a feature, it’s a foundation. As software becomes more integral to daily life, ensuring that systems are usable by everyone is a professional and ethical imperative.
Accessibility: A core component of quality
Accessible design means more than compliance. It means inclusivity, improved user experience, and a broader reach. For software testers and developers, integrating accessibility into projects from the start is a sign of maturity and commitment to quality.
When digital products are not designed with accessibility in mind, the consequences are real: people are excluded from using services, companies face legal challenges, and reputations suffer. With an estimated 1 in 5 people in the UK having a disability, inclusive design is not niche; it’s a necessity.
Legal and ethical responsibilities
In the UK and many other countries, there are clear legal requirements for digital accessibility:
- Equality Act 2010 (UK) mandates that organisations must not discriminate against people with disabilities, including through inaccessible websites or apps
- Public Sector Bodies (Websites and Mobile Applications) Accessibility Regulations 2018 reinforce the requirement for public services to meet WCAG 2.1 AA standards
- Web Content Accessibility Guidelines (WCAG) are internationally recognised standards that define how to make content more accessible
Non-compliance can lead to reputational damage, legal action, and financial penalties. But more importantly, it undermines trust and usability for millions.
Why software testers are critical to inclusive development
Software testers play a vital role in accessibility:
- Identifying non-compliant interfaces
- Running accessibility audits and user tests
- Ensuring compatibility with assistive technologies
- Validating against WCAG criteria in Agile sprints and release cycles
Accessibility isn’t a final-stage checklist. It must be part of continuous integration and testing. When testers are trained to recognise barriers and implement inclusive thinking, the resulting software is more robust, ethical, and effective.
Incorporating accessibility into Agile and ISTQB frameworks
Agile development encourages iterative improvement and cross-functional collaboration. That makes it an ideal model for embedding accessibility:
- Agile user stories can include accessibility acceptance criteria
- Sprint reviews can showcase inclusive design improvements
- Definition of done should include accessibility checks
Similarly, the ISTQB certified tester syllabus promotes quality-focused practices that align well with accessibility goals. In particular:
- The ISTQB Advanced Test Analyst certification includes test techniques that help evaluate usability and accessibility
- Risk-based testing approaches taught in ISTQB encourage prioritising issues that affect the broadest user base, including those with disabilities
These frameworks provide the structure and language testers need to influence accessibility from within the delivery process.
At TSG Training, we offer targeted courses that help testers build accessibility into their skillset and become advocates for inclusive quality assurance:
If you’re starting out in testing, this course provides the essential principles of structured testing, including quality characteristics that support accessibility.
Deepens your understanding of system quality characteristics, including usability and accessibility. Learn how to design, prioritise, and execute tests that go beyond functionality.
Our Agile Tester Extension or AgilePM courses help you integrate accessibility into the agile delivery cycle from backlog to delivery.
On Global Accessibility Awareness Day
Whether you’re a tester, developer, or project manager, here are a few ways you can contribute:
- Audit your own products
- Champion accessibility in team meetings
- Enrol in training
- Review your definition of done
- Share resources with your team
Inclusivity is quality
Accessibility isn’t just about ticking compliance boxes. It’s about recognising that great software serves everyone. By integrating accessibility testing into your process and upskilling your team, you create digital experiences that are resilient, usable, and truly inclusive.
