An accessibility certification program can refer to an organization’s internal training and validation track for its own staff, or to external professional certifications like IAAP’s CPACC, WAS, and CPWA that individuals pursue to formally validate their accessibility expertise to employers and clients.
Organizations building internal certification programs often use recognized external certifications like IAAP’s as a foundation or benchmark, layering on company-specific tools, workflows, and design system knowledge so staff can apply accessibility principles correctly within that organization’s own products.
