50 STEM Competitions for Students in 2026
By Rishab K. Jain
There are lots of STEM competitions available for high school students to participate in. Here, I’ve pulled together 50 that I know to be worthwhile.
1. International Science and Engineering Fair
I’ve competed at ISEF for 4 years. It’s the world’s largest pre-collegiate science fair with something like 1600+ students. To truly capture how cool ISEF is, watch my vlog:
The prizes at the International level are in the tens of thousands. In 2022, I won the $50,000 Regeneron Young Scientist Award at ISEF.
Ok, that being said, how do you even get started with ISEF / science fair in general?
ISEF is affiliated with a ton of regional and state-level fairs around the world. Once you win at those, you can win a spot, qualifying you to go to ISEF.
Winning ISEF is an art of its own. If you want help, ScienceFair offers coaching with past winners.
There's a list to help you find your local fair to qualify for ISEF.
Once you find your local fair, contact the coordinator and see how to register! This opportunity truly changed my life.
In 2026: It will be held May 9th-15th, 2026 in Phoenix, Arizona.
2. ThermoFisher Junior Innovator Challenge
Eligibility: Middle School level, US student
I competed in the Broadcom MASTERS which is now the ThermoFisher JIC challenge all three years of middle school. In 2017, I was an entrant. In 2018, I was a semifinalist (top 300), and in 2019, I was a finalist (top 30) and competed at Nationals, winning 2nd place.
This is the premier science fair for middle schoolers, and works similarly to ISEF in that you compete at your local district/state level fair in order to qualify.
The final competition is held in Washington, D.C., and is a lot of fun.
In 2026: Applications open of February 1st, 2026.
3. 3M Young Scientist Challenge
Eligibility: US student, grades 5-8
