Welcome to the American Computer Science League
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 300 teams in
the United States, Canada, Europe, Africa and Asia are participating
in various divisions. 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. But read on, if you are in Korea, Viet Nam, China, or Egypt.
We are super excited to announce a partnership with
the Academic Consulting and Education
group for students in Korea (www.kcsl.acsl.org) and Viet Nam
(www.vcsl.acsl.org). Students in those
countries will particpate in the 4 regular season contests at a local
site; schools will be reported in the ACSL leaderboard and top schools
will be invited to the All-Star Contest.
We are also excited to partner with ASDAN China
to administer the ACSL contests in China.
Schools participating via ASDAN (register using the link
will take the ACSL contests translated into Chinese. Schools in China
may also register directly with ACSL.
We are also excited to be partnering
with Ideasgym in Egypt.
Try out some sample contests to get a flavor
of our contests.

videos showing sample question solutions is available on the ACSL
