What are the eligibility requirements for participating in the IOI?

The International Olympiad in Informatics (IOI) is an annual programming competition for secondary school students from around the world. To be eligible to participate, students must meet the following requirements:

• Be no older than 20 years of age on July 1st of the year in which the competition takes place.
• Be enrolled in a secondary school or equivalent institution, and not enrolled in a post-secondary program.
• Meet any additional requirements or qualifications set by their country's IOI committee.

Students who meet these eligibility requirements and wish to participate in the IOI must first compete in national-level programming competitions in their home countries, with top performers being selected to represent their country at the IOI.

The eligibility requirements for participating in the IOI are as follows:

• The student must be enrolled in a school for secondary education in the country they are representing.
• The student must not be older than 20 years on the 1st of July of the year of the IOI.
• The student may represent the country of their nationality, even if they are studying abroad.

In addition to these eligibility requirements, each country may have its own additional requirements. For example, some countries may require students to pass a qualifying exam or to have a certain level of academic achievement.

The IOI is a prestigious competition that attracts some of the brightest minds in computer science from around the world. If you are interested in participating, I encourage you to check with your national olympiad committee for more information.
