Our Mission

The USACO supports computing education in the USA and worldwide by identifying, motivating, and training high-school computing students at all levels. We provide:

• Hundreds of hours of free on-line training resources that students can use to improve their programming and computational problem-solving skills.
• On-line programming contests (roughly six per year) for students at all levels.
• An intensive summer training camp, to which the top students in the USA are invited to further improve their skills and learn advanced material.
• The opportunity for the top four students in the USA to represent their country at the International Olympiad in Informatics (IOI), the most prestigious international algorithmic programming competition at the high-school level.
