High School Summer Diplomacy Program

Discover a career in diplomacy.

At the NSLC on International Diplomacy, you’ll assume the role of a diplomat for the United Nations, engaging in discussions that mirror the challenges of real-world foreign policy. Explore the principles of international relations as you debate current events, navigate global power dynamics, and learn how cultural and economic factors influence negotiation and cooperation. Gain firsthand experience in how diplomacy, communication, and leadership work together to resolve conflict and shape the future of global relations.

The NSLC is proud to partner with the American Foreign Service Association to help provide students with a greater understanding of diplomacy and global affairs.

It was an amazing experience. I made new friends, learned new things and got a broader perspective on international relations. Now I want to study it even more than before.
