15 Computer Science Competitions for High School Students
Computer Science competitions are a great way to not only improve your skill set but also demonstrate your motivation and dedication in the college application arena. Regardless of whether you win a competition, even participating in them can demonstrate these qualities. They can show college admissions officers your willingness to challenge yourself and grow. If you are passionate about CS, eager to grow your skills, and curious about how you can do so – CS competitions are the way to go.
How can you identify the best CS competition?
Everyone is at different levels with respect to their skillset. So when choosing competitions to participate in, it is important to select a competition that would be a fair challenge to your abilities. Here are some tips on selecting the best competitions for you to contest in!
The first thing to try and do is identify your areas of interest and the skills you’re strong in within computer science. This will help you target competitions that align with your strengths and passions.
It is also important to understand the format of each competition. Some may focus on individual performance, while others encourage team participation. Also, consider the duration of the competition—whether it's a one-time event or spans over a longer period.
Lastly, Research and learn from past competitions to understand the types of challenges, topics, and problem-solving techniques involved. Consult your computer science teachers, or mentors who know about your coding ability well enough to provide insights and recommendations based on their experience.
What are the different types of CS competitions?
There are a lot of different types of CS Competitions out there. So regardless of what you’re interested in, you’ll probably be able to attend a competition for it! We’ve organized some of them here.
a. Programming competitions: If you have a strong preference for coding or algorithmic problem-solving, then these types of competitions might interest you. These competitions usually have a strict time frame within which teams of students have to solve a set of programming problems within certain languages.
b. Robotics competitions: If you’re interested in robotics and CAD (computer aided design), there are a lot of robotics competitions out there for high school students! These are also team based in nature, and will also test your team’s engineering skills.
C. Cybersecurity: If you’re interested in cybersecurity and computer networking concepts like IP addressing, routing, and more, then Cybersecurity competitions are a great way to challenge and develop your skill set in those regards.
While these are the broader types of competitions, there are several more out there for other specialized interests. There are App Development challenges – as seen in the Congressional App Challenge, or more dynamic development challenges like the Imagine Cup. So with that, here’s our compiled list of 15 Computer Science competitions for high school students!
