To thrive as an Accessibility Tester, you need a solid understanding of accessibility standards (such as WCAG), knowledge of HTML/CSS, and experience with manual and automated testing methodologies. Familiarity with tools like screen readers (JAWS, NVDA), accessibility evaluation software (axe, WAVE), and certifications like CPACC or WAS are highly valuable. Strong attention to detail, effective communication, and teamwork are standout soft skills in this role. These abilities are critical to identifying barriers, ensuring digital accessibility, and collaborating with developers to deliver inclusive user experiences.
