Conradh na Gaeilge is made up of over 200 branches in Ireland and abroad, working as part of a national movement for the Irish language. Branches are made up of people, usually volunteering, to achieve aims and goals. Some of the branches are focused on specific areas (like Craobh Chathair Luimnigh, Craobh Londan), and some are subject specific (like Craobh Na Gaeil Óga, Craobh Raidió Rí-Rá).
The Irish Language Officer plays an important role in the Students' Union. They are usually responsible for the Union's approach to the Irish language, and as the Union represents thousands of students, the Irish Language Officer is responsible for ensuring Irish language rights for these thousands of people, as well as standing up for the Irish language and Irish speakers on campus.
