  • Crimson Education

Multiple Competition Certification Skill Building Other


The students have to test their skills in all major areas of Earth sciences, including geology, geophysics, meteorology, oceanography, terrestrial astronomy and environmental sciences. The theoretical examination includes problems which are supposed to measure the participants’ knowledge and understanding of Earth science areas. The practical examination consists of tasks which are designed to assess participants’ abilities to carry out scientific investigations in earth science inquiries.

The examinations are prepared by specialists in Earth sciences and Earth science education, who also provide solutions and evaluation guidelines. Each delegation is composed of 4 students and 2 supervisors. The latter must be specialists in Earth science and Earth science education and capable of serving as members of the International Jury. The official language of IESO is English; however, the supervisors may translate the written examinations and related materials into to the participants’ native language.

The main aim of the IESO is to encourage students’ interest and public awareness of Earth Science and to enhance Earth science learning. The IESO the organizers hope to pick out talented and gifted Earth science students and to promote the improvement of teaching Earth sciences at schools. Last but not least, the IESO is developed in pursuit of encouraging friendly relationships among young learners from different countries and promoting international cooperation in exchanging ideas and materials on Earth sciences and Earth sciences education.

The IESO is the only International Olympiad that includes an International Team Field Investigation – ITFI. The last International Team Field Investigation focused on: developing stratigraphic sequences, evaluating living on the Mt. Mayon volcano, and evaluating the fault escarpment of the Chi-Chi earthquake. In 2010 in Indonesia the International Team Field Investigation focused attention on sustainability and use of the underground water. Thus, ITFI turns out to be a special IESO tool to encourage friendly relationships among young learners from different countries and to promote international cooperation.

Please note that the IESO 14th IESO, 2020, Tyumen, Russia has been cancelled due to the threat of the spread of the new coronavirus and the measure taken to combat the spread of infection.
