Hong Kong Olympiad in Informatics is an annual programming competition for secondary school students in Hong Kong, emphasizing on problem solving techniques and programming skills. It is co-organized by the Hong Kong Association for Computer Education (HKACE) and the Hong Kong Education Bureau (EDB). It serves as a preliminary contest to international, national and regional competitions such as the China National Olympiad in Informatics (NOI) and the International Olympiad in Informatics (IOI). The first HKOI was held in 1997.
The United States of America Mathematical Olympiad (USAMO) is a highly selective high school mathematics competition held annually in the United States. Since its debut in 1972, it has served as the final round of the American Mathematics Competitions. In 2010, it split into the USAMO and the United States of America Junior Mathematical Olympiad (USAJMO).
The American Mathematics Competitions (AMCs) are the first of a series of competitions in secondary school mathematics sponsored by the Mathematical Association of America (MAA) that determine the United States of America's team for the International Mathematical Olympiad (IMO). The selection process takes place over the course of roughly five stages. At the last stage, the US selects six members to form the IMO team.
Science Olympiad is an American team competition in which students compete in 23 events pertaining to various fields of science, including earth science, biology, chemistry, physics, and engineering. Over 7,800 middle school and high school teams from 50 U.S. states compete each year. U.S. territories do not compete; however, several international teams do compete in Science Olympiad tournaments in the US.
The United States of America Computing Olympiad (USACO) is an online computer programming competition, which serves as qualification for the International Olympiad in Informatics (IOI) in the United States of America. Primarily for secondary school students in the United States, the USACO offers four competitions during the academic year. Participants compete in four increasingly difficult divisions, each of which is provided a distinct set of 3 solvable competitive programming problems during each contest. Coding & submitting computer programs can be done in one of four languages: C, C++, Java, and Python. Competitors begin in the Bronze division, and advance through the levels by performing well in their current division.
The Central European Olympiad in Informatics (CEOI) is an annual informatics competition for secondary school students. Each of the participating central European countries (plus one or two guest countries, and a local team from the host area) sends a team of up to four contestants, a team leader and a deputy team leader. The contestants compete individually, i.e. a team score is not calculated. Competitors are selected through national competitive programming contests.
The Mathematical Olympiad Program is an intensive summer program held at Carnegie Mellon University. The main purpose of MOP, held since 1974, is to select and train the six members of the U.S. team for the International Mathematical Olympiad (IMO).
The Tournament of Towns is an international mathematical competition for school students originating in Russia. The contest was created by mathematician Nikolay Konstantinov and has participants from over 100 cities in many different countries.
The Bangladesh Mathematical Olympiad is an annual mathematical competition arranged for school and college students to nourish their interest and capabilities for mathematics. It has been regularly organized by the Bangladesh Math Olympiad Committee since 2001. Bangladesh Math Olympiad activities started in 2003 formally.
The Indian Computing Olympiad is an annual computer programming competition that selects four participants to represent India at the International Olympiad in Informatics. ICO is conducted by the Indian Association for Research in Computing Science. The competition is held in three stages. For the first stage, students may compete in the Zonal Computing Olympiad, or the Zonal Informatics Olympiad. The following two rounds are the Indian National Olympiad in Informatics and the International Olympiad in Informatics Training Camp.
This article describes the selection process, by country, for entrance into the International Mathematical Olympiad.
The International Philosophy Olympiad (IPO) is an annual philosophy competition for high school students from around the world, one of the International Science Olympiads. It is organized under the auspices of the International Federation of Philosophical Societies (FISP) and supported by UNESCO.
Mathematical Grammar School, is a special school for gifted and talented students of mathematics, physics and informatics located in Belgrade, Serbia.
The China Girls' Mathematical Olympiad (CGMO) is a math competition with a proof-based format similar to the International Mathematical Olympiad. The competition is organized by the Chinese Mathematical Society. Owing to the fact that girls are outnumbered by boys in mathematical competitions, this competition was created specifically for girls. The aim of the CGMO is to encourage more girls to study mathematics and to foster friendship. It was originally organized in 2002 for teams of girls representing different regions within China. The Chinese organizers decided to invite other nations to send teams of girls from their countries. The Philippines has participated since the first edition. Russia has participated at least since 2004. The United States participated in 2007–2012. Singapore has also participated.
The United Kingdom Linguistics Olympiad (UKLO) is a linguistics competition for primary and secondary school students in the United Kingdom. The competition is divided into four levels: Breakthrough, Foundation, Intermediate and Advanced, collectively known as 'Round 1', with the top-scoring 5% of entrants at Advanced level eligible for a follow-on round, called 'Round 2' and selection for participation in the International Linguistics Olympiad, one of the international science olympiads. In 2009, teams from two schools competed in a pilot competition, with the winners taking part in the international contest as guests of the All-Ireland Linguistics Olympiad. In 2010, an independent olympiad was created and has taken place every year since.
