The foremost competition for Earth Science in the United States, USESO aims to promote and inspire education of the Earth and its global systems to students across the nation. After a national open exam, forty students are invited to participate in a week-long residential program at the University of Vermont. The program allows students to hone their field work skills and deepen their understanding of the complex systems that govern our planet. At the conclusion of the program, the eight students are selected to represent USA at the International Earth Science Olympiad (IESO). For more specific details, see USESO Training Camp.

If you are a student interested in becoming a member of the U.S. Earth Science Team, please read through this entire site and register for the Open Exam. If you make the international team, you will have the opportunity to travel to a foreign country, work to communicate your knowledge of Earth Science, and work with a team of students from all over the world. Visit the France IESO Website to get a sense of what past IESOs have been like, as well as the official IESO site for general information.

If you are a teacher, please consider encouraging your students to step up to this challenge, and feel free to take advantage of the IESO-based classroom activities posted on this website.

What is IESO?

The International Earth Science Olympiad is organized under the guidance of the International Geological Education Organization (IGEO). Each year, the top Earth Science students from over forty participating countries attend the IESO. At the IESO, students are assessed for individual content knowledge in the various Earth Systems, including the Geosphere, Atmosphere, Hydrosphere, and Solar System Astronomy.

Beyond the individual competition, students also participate in the International Team Field Investigation (ITFI). Working in small teams composed of students from all over the world, students are given a “real world” Earth science related challenge to solve together. After conduction field work, data collection, and online research, students present their conclusions in a cohesive presentation to a jury of professors, politicians, and professionals. The aim of this investigation is to promote the international cooperation essential to mitigation of the serious, real world Earth science issues facing humanity, ranging from ocean acidification, sea level fluctuation, climate destabilization, and widespread plastic pollution. Communication among scientists from around the globe is critical to solving these issues. This work starts at the IESO.
