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 39th 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.

This year, we are starting a division for elementary schools (grades 3 through 6), consisting of 5 questions for a computer science topic such as Boolean Algebra and Graph Theory. Not to worry - the material is presented at a level geared to elementary school students. Check out the presentation about the new Elementary Division (it's also available as a PowerPoint presentation.)

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

Schools that are participating in the 2018 All-Star Contest should refer to our All-Star Contest Info page.
