The European Girls’ Mathematical Olympiad (EGMO) is the open European championship in mathematics for female high school students. It was initiated by the United Kingdom, which hosted the first edition of the event in April 2012. In this inaugural EGMO, nineteen countries participated. Since then, the EGMO has been held annually in different European countries, and has grown rapidly to more than fifty participating countries. Even though the EGMO is a European competition, non-European guest countries may participate in the EGMO as well. In 2020, the EGMO will take place in the Netherlands. This edition is expected to welcome approximately forty European participating countries, as well as a large number of non-European guest countries.
The goal of the EGMO is to stimulate girls to participate in both national and international mathematics competitions, and to give more girls the opportunity to perform mathematically on an international stage. A desired effect of the EGMO is that more girls will participate in the International Mathematical Olympiad, where girls currently make up only 10% of the participating students.
Any participating country may send up to four students to participate in the competition. These students compete individually, and write two contest papers on consecutive days, with three problems on each day. For each problem, the students receive an integer score out of a maximum of seven marks.
After the marks have been determined, gold, silver, and bronze medals are awarded for excellent performances. Medals are awarded to approximately half of the participating students. Gold, silver and bronze medals are awarded in the ratio of 1:2:3, so that about 8% of the students obtain a gold medal, about 17% of the students obtain a silver medal and about 25% of the students obtain a bronze medal. In order to encourage more students, and to encourage students to solve problems completely, any student (not receiving a medal) who obtained full marks for at least one problem receives a certificate of honourable mention.
