10 STEM Competitions for High School Students

Participating in high school STEM competitions is not only a strong extracurricular experience to have under your belt but also an important stepping stone in your field of interest. These competitions help you hone your discipline and quick thinking, and can also help qualify you for college scholarships. 

The rigorous preparation and forethought involved aid you in becoming a competitive college admissions or internship candidate and also impart much-needed real-world, hands-on experience in STEM. Even if you don’t come out as a winner, your participation ensures that you have learned key aspects of your chosen STEM discipline. 

We’ve compiled a diverse and prestigious list of 10 STEM competitions for high school students that should help you forge a path and truly study what interests you!

We’ve shortlisted these competitions on the basis of selectivity, whether they’re backed by prestigious institutions (such as NASA or ISEF), and overall rigor and depth of judging criteria. 

You can take a look at our blog on prestigious internships in STEM here. 

ISEF is unmissable if you’re passionate about STEM. The multi-stage fair requires months of preparation preceding its week-long final event and attracts students from 80 countries worldwide. 

Over 600 individual and team awards are presented each year with cash prizes for category awards ranging from $500 to $3,000. First-place winners in each category qualify for twelve ISEF Top Awards, whose winner receives an award of $75,000, with two runner-ups receiving $50,000 each. Additional awards worth $4 million are provided through the ISEF Special Awards Program.

The 22 categories offered in 2024 include Biochemistry, Systems Software, Technology Enhances the Arts, Physics and Astronomy, Materials Science, Robotics and Intelligent Machines, Computational Biology and Bioinformatics, and Environmental Engineering.
