To thrive as a Section 508 Tester, you need a solid understanding of accessibility standards (especially Section 508 and WCAG), testing methodologies, and experience with manual and automated accessibility testing. Familiarity with tools like JAWS, NVDA, Axe, and WAVE, as well as knowledge of HTML, CSS, and ARIA, is highly beneficial, and certifications like IAAP CPACC are often preferred. Strong attention to detail, communication skills, and the ability to clearly document and explain accessibility issues set outstanding testers apart. These capabilities ensure digital products are accessible, compliant, and inclusive for users of all abilities, minimizing legal risk and supporting organizational goals.
