In 2021 the FIC board of directors endorsed the French canyon rating system as the international standard.  It took a few years of discussion with canyoneers from many countries to arrive at this decision. The classification system does not include the American rating system which includes difficult dry canyons. A marriage between these two systems could not be found. The international system will most likely undergo minor modifications year by year. The primary document was written in French. Deepl was used to translate it to English.
