US Open

Results of the USACO 2017 US Open contest are available here.

The US Open serves as our national championship contest, and is typically given high weight when selecting finalists to invite to our summer training camp. We will be announcing finalists to attend our training camp within the next few weeks.

Finalists for 2015-2016 Season Announced

The USA Computing Olympiad is pleased to announce its finalists for the 2015-2016 season.

2015-2016 Season Schedule Announced

The schedule for the USACO 2015-2016 season is now posted! Like the previous season, we will be holding a series of three on-line contests, starting in December, followed up with the US Open, our national championship contest. All are welcome to participate!

In a change from the past few years, contests will now be available in four levels of difficulty: bronze, silver, gold, and platinum. The new platinum division will be populated initially with USACO finalists from previous years, and others can earn promotion during or after each contest. The old bronze, silver, and gold divisions will be scaled down in difficulty accordingly, so that bronze contests will provide an easier entry-level experience for our new competitors (we've received overwhelming feedback requesting this) and so it will be less of a discontinuity for students to compete in higher divisions after promotion. Platinum-level contests will be roughly comparable to the difficulty level of prior-year gold contests.

Great Results for Team USA at IOI 2015!

Congratulations to Andrew He (gold), Demi Guo (silver), Alexander Wei (gold), and Daniel Chiu (gold), for one of the best showings ever for the USA team, at the 2015 International Olympiad in Informatics in Almaty, Kazakhstan!

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.

Finalists for 2014-2015 Season Announced

The USA Computing Olympiad is pleased to announce its finalists for the 2014-2015 season! These 24 indidivuals will be attending the USACO summer training camp and competing to represent the USA at the 2015 International Olympiad in Informatics.

Team USA Wins Solid Gold at IOI 2014!

Congratulations to team representing the USA at the 2014 International Olympiad in Informatics in Taipei, Taiwan! -- Andrew He, Steven Hao, Scott Wu, and Joshua Brakensiek. All four won gold medals, and Scott Wu tied for first place with a perfect score after completing the contest in nearly half the allotted time! A truly remarkable result, and perhaps the best ever for team USA!
