Welcome to the American Computer Science League (ACSL)!

ACSL organizes computer science contests and computer programming contests for elementary, junior, and senior high school students. This year, our 41st year of continuous operation, over 200 teams in the United States, Canada, Europe, Africa and Asia are participating. ACSL is on the approved activities list of the National Association of Secondary School Principals (NASSP). ACSL is also an institutional member of the Computer Science Teachers Association.

We welcome participation from all pre-college schools around the world. Check out some sample contests to get a flavor of our contests.
