Conclave is held biennially (every two years) on the even numbered calendar years. The purpose of the Conclave is to get the representatives from all chapters and colonies together for a business meeting and to build and share camaraderie and Brotherhood.
When all of the attendees get together, they first participate in a fun filled brotherhood experience that gives everyone to get to know each other and bond as Brothers of Phi Sigma Phi. Past events have included attending baseball games, bowling, a tour of the Notre Dame Football stadium, go-karts races, and dinners among other activities.
The Business Meeting consists of voting for National Officers, budget information, National Constitution and By-Law changes or updates, chapter reports and more. Chapter representatives vote and approve and have a voice in fraternity affairs and legislation. The formal dinner is followed by a speaker, and National Fraternity Awards for Chapter and individual achievements are given out.
