Key findings
These are the most common accessibility issues we see on Duolingo's site type.

Why Accessibility Matters for Duolingo
Language learning relies on audio, visual, and interactive elements. Deaf users need visual alternatives for listening exercises, blind users need accessible gamification elements, and motor-impaired users need keyboard-friendly drag-and-drop alternatives.
What this means
A score in the C range suggests there are likely barriers for keyboard and screen reader users. While this is not legal advice, it indicates potential ADA and WCAG 2.1 AA compliance gaps that could affect usability and increase lawsuit exposure.
Business impact
Missed conversions from users who rely on assistive technology, plus higher support costs from inaccessible flows.
Compliance impact
ADA lawsuits often cite WCAG failures like contrast, labels, and keyboard access. Addressing the top issues closes the biggest gaps.
