The Yale International Relations Leadership Institute (YIRLI) is an intensive, exhilarating summer institute. Students from around the world explore international relations, enhance leadership and public speaking skills, and engage with pressing global issues through an entrepreneurial lens. The program includes Model United Nations and debating workshops led by Yale students, opportunities to learn from Yale professors and visiting speakers, and participation in the YIRLI Global Impact Challenge related to the UN Sustainable Development Goals.
Cycle status checked November 4, 2026: the official General Information and Application pages describe the historical July 28–August 2, 2026 session and explicitly mark applications closed. The 2026 program dates and March 30 deadline above are retained as history; dates and eligibility for the next session have not been announced in these sources. The General Information page consistently identifies the session as 2026, although the program page and FAQ contain a stale “YIRLI 2025” label beside 2026 dates.
The listed $2,200 program fee and aid amount describe 2026 only, not an announced later-cycle price or guarantee of aid. The 2026 financial aid page aimed to meet demonstrated need, offered an application-fee waiver, and excluded flights and visas. The FAQ also restricted 2026 attendance to new participants. These historical rules must not be assumed for a future session.
