The International Olympiad in Informatics (IOI) is an annual competitive programming competition and one of the International Science Olympiads for secondary school students. The first IOI was held in 1989 in Pravetz, Bulgaria. It is the second largest science olympiad, after the International Mathematical Olympiad, in terms of number of participating countries. Each country sends a team of up to four students, plus one team leader, one deputy leader, and guests.
The International Mathematical Olympiad (IMO) is a mathematical olympiad for pre-university students, and is the oldest of the International Science Olympiads. It is “the most prestigious” mathematical competition in the world. The first IMO was held in Romania in 1959. It has since been held annually, except in 1980. More than 100 countries participate. Each country sends a team of up to six students, plus one team leader, one deputy leader, and observers.

The United Kingdom Mathematics Trust (UKMT) is a charity founded in 1996 to help with the education of children in mathematics within the UK.
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 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. The 1994 US IMO Team is the first of the only two teams ever to achieve a perfect score, and is colloquially known as the "dream 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.
Badminton had its debut as an official event on the 1992 Summer Olympics and has been contested in eight Olympiads. 74 different nations have appeared in the Olympic badminton competitions, with 18 appearing all eight times. It is governed by the Badminton World Federation.
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 British Mathematical Olympiad (BMO) forms part of the selection process for the UK International Mathematical Olympiad team and for other international maths competitions, including the European Girls' Mathematical Olympiad, the Romanian Master of Mathematics and Sciences, and the Balkan Mathematical Olympiad. It is organised by the British Mathematical Olympiad Subtrust, which is part of the United Kingdom Mathematics Trust. There are two rounds, the BMO1 and the BMO2.
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.
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 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.
