USI is the national representative body for the 374,000 students in third level education on the Island of Ireland. We are a membership organisation – our members are our affiliated Students’ Unions around Ireland, North and South.

USI is a democratic organisation. The supreme authority of the Union is Comdháil (Congress), which is representative of each affiliated students’ union, apportioned according to the size of the student body in each union. Each union also sends one voting member to Comhairle Náisiúnta (National Council) – the executive body of the organisation.  Issues relating to governance are delegated by the National Council to a Governance Committee.  Day to day management and policy execution are delegated by USI Comdháil to an elected committee of Sabbatical student representatives called the Coiste Gnó (Executive Team).
