Prelude is one of the ways we support and recognize our directors. Global Conferences, organized by ACIS, give qualifying directors an opportunity to experience destinations firsthand, develop ideas for future group travel, and connect with fellow educators. Each hosted program combines guided visits, cultural experiences, and practical destination research that can inform a future Encore tour. While no two conferences are exactly alike, each includes airfare, accommodations, breakfasts, planned excursions, and other program elements. Where permitted by program terms and the rules of your school, district, or organization, you may also bring a companion. To qualify for a Global Conference, you must have 20 paying participants on an international trip before July 15, or 25 paying participants before October 15. Participation is subject to availability, program terms, and the rules of your school, district, or organization. Upcoming Global Conferences Explore our upcoming opportunities for destination research, professional connection, and travel from late 2026 through summer 2028.
