The American Computer Science League (ACSL) is the oldest and longest-running computer science competition for high school students in the United States. Founded in 1978, the ACSL is focused on promoting computer science education and fostering interest in computing careers.
The ACSL organizes contests throughout the academic year that test students' programming knowledge and computational thinking skills. Teams from middle schools and high schools across the U.S. and Canada participate in the ACSL competitions.
The ACSL contests feature complex programming problems and algorithmic challenges that students must solve in a set amount of time. There are multiple divisions based on grade level, so the competitions are designed to be challenging yet fair for participants. Teams compete within their regions for a chance to advance to the national finals.
The ACSL aims to inspire future computer scientists and recognize student excellence in computing skills. Participating in the ACSL competitions allows students to test themselves against rigorous problems, develop critical thinking abilities, and gain exposure to new CS concepts. Overall, the ACSL serves as an enriching and motivating computer science experience for youth.
Eligibility and Divisions
The American Computer Science League (ACSL) is open to students in grades 6-12. Participants compete in teams organized by their school, although some contests allow individual entries as well.
There are five divisions based on grade level:
- Intermediate Division: Grades 6-8
- Junior Division: Grades 9-10
- Senior Division: Grades 11-12
- Collegiate Division: Undergraduate students
- Open Division: Open to all eligible contestants
Teams can have up to 8 members, with the top 4 scores counting towards the team total in each contest. Students can also compete as individuals if their school does not have enough interested students to form a full team.
Schools must register in advance to participate in the ACSL contests. The registration period is from September to December before the competition season begins. There is a registration fee per school, plus an additional fee per student competitor. Some regional chapters may have additional local fees.
To register, schools should find and contact their local ACSL chapter. The chapter will provide the registration link and payment information. Registration provides access to the 5 contests during the ACSL season from February to April.
Contest Format and Scoring
The ACSL competition consists of 5 contests held throughout the regular academic year from November to March. There are separate contests for the different grade-level divisions.
The contests involve a variety of computer science problems testing skills such as programming logic, coding, algorithms, and mathematical applications. The problems range from beginner to advanced levels, getting progressively more difficult through the season.
Some example problems include:
- Analyzing code snippets and identifying errors
- Tracing program execution and predicting output
- Solving logic puzzles and coding challenges
- Applying computational thinking to real-world scenarios
The contests have 30-40 multiple choice questions to be solved within 30 minutes. Questions have different point values based on difficulty level. No computers or calculators are allowed during the contests.
Scoring is based on the total points accumulated across all 5 contests. The minimum score needed to qualify for the finals varies by division. Tie-breakers are determined by the number of high value questions solved.
The top-performing students nationwide advance to the final Championship round held in May. The finals follow a similar testing format as the regular season. National and regional winners are recognized based on final contest rankings.

Preparation and Practice
Proper preparation is key to succeeding in ACSL contests. Here are some tips for getting ready:
Practice Problems
- Work through ACSL's official practice problem sets. These will give you exposure to the types of questions asked.
- Use online judges like USACO, Codeforces, and LeetCode to practice coding questions. ACSL includes programming challenges.
- Ask your teacher for past ACSL contests to use as practice tests. Mimic the real testing environment.
- For the team contest, do mock run-throughs with classmates to practice collaboration.
Time Management
- Budget your time wisely during the contest. Don't get bogged down on one problem.
- For the programming questions, think through the logic and pseudocode first before coding.
- Skip problems you're stuck on and come back later. Don't waste too much time upfront.
- Pace yourself to finish at least 30 minutes early to review your work.
Problem-Solving Strategies
- Read questions thoroughly and identify what they are asking.
- Break down complex problems into smaller, manageable steps.
- Draw diagrams, charts, or tables to visualize the concepts.
- Look for patterns and themes across questions to identify optimal solving approaches.
- Double check units and be careful of rounding when doing calculations.
- Write clean, organized code with descriptive variable names and comments.
Tips for Success
To excel in the ACSL contests, students should focus on developing strong analytical thinking, teamwork, and diligent practice. Here are some top tips:
Sharpen Analytical Skills
The ACSL contests require logical thinking and problem-solving abilities. Students should work on breaking down complex problems into smaller steps, identifying patterns, and developing algorithms. Practicing logic puzzles and brain teasers helps strengthen critical analysis. Learn to think through all possibilities methodically to uncover the optimal solution.
Emphasize Teamwork
Collaborating with teammates allows students to brainstorm ideas together. Teams should discuss strategies and provide feedback to harness their collective strengths. Splitting up roles and responsibilities ensures everyone contributes. Communication, delegation, and time management are key. The synergy of a team is greater than the individual.
Practice Consistently
Diligent preparation is vital for ACSL success. Students should solve many practice problems under timed conditions to simulate the real contest. Review previous ACSL questions and understand the test format. Analyze mistakes to identify weak areas. Maintain speed and accuracy through regular practice. Set incremental goals to benchmark progress. Consistent practice builds exam confidence and readiness.
With analytical thinking, teamwork, and practice, students can develop the skills to excel at the prestigious ACSL contests. These tips help unlock students' true potential for computer science excellence.
Awards and Recognition
The ACSL offers various awards and recognition for top performers, providing great accomplishments to highlight on college applications and resumes.
