10 Best Chemistry Competitions for High School Students

Are you passionate about chemistry? Then you should read this blog because we outline some of the top chemistry competitions for high school students.

Why compete in a chemistry competition?

One of the best ways to showcase your abilities is to compete against other people interested in the same field. If you’re able to win, this has a high signal for you in the college admission process. It’s also a great way for you to go deeper into an area of your own interest and learn!

How prestigious is winning a competition? Does it help in college applications?

Depending on the competition, winning can be a very significant extracurricular boost. Usually winning a competition falls under the academic achievement or awards section of an application. If you’re looking to study chemistry in college, showcasing your knowledge through a competition can help you stand out against other chemistry applicants. ,

We've compiled a list of 10 competitions perfect for any chemistry enthusiast, ranging from fellowships to olympiads at the national and international levels to innovation challenges.

Not exactly what you are looking for? Check out our list of other competitions in biology, math, computer science, economics, entrepreneurship and art and design.
