Which organization provides rules and guidelines for braille?

The Braille Authority of North America (BANA) is the organization responsible for establishing rules and guidelines for braille usage specifically in North America. BANA serves to maintain the standardized practices for braille literacy and employment, ensuring consistent communication and educational practices across various contexts. Through its guidelines, BANA helps practitioners, educators, and manufacturers provide high-quality braille materials that adhere to recognized standards, allowing individuals who are visually impaired to access and use braille effectively.

The other organizations listed focus on different aspects of braille and its promotion or education, but they do not set the official rules and guidelines like BANA does. This distinction underlines why BANA is recognized as the authoritative body for braille standards in the region.
