Picture this: it’s 10 p.m. on a school night. One student is in the garage, measuring how algae growth changes under different light colors. Another is at a kitchen table, solving physics problems. A third is on a video call with teammates, designing a bridge that can survive an earthquake simulation. All three are “doing science competitions,” but in completely different ways.
Major science competitions can look similar: big titles, trophies, scholarships, and pressure. However, the experience, preparation, and skills developed can vary greatly depending on your choice. Here on ScholarComp, we’ve put together this guide to help you compare the major science competitions to choose the ones that truly fit your strengths, goals, and schedule.
This article is part of the “Inside Science Competitions” series. If you want to dive deeper into what happens behind the scenes, you can pair this with pieces like What Really Happens at Science Competition Day or How Science Competitions Are Scored and Judged.
Before comparing individual competitions, it helps to understand the main “families” they fall into:
Recognize which type of science work energizes you, then choose competitions that align with that. The rest of this article compares the major competitions by category.
Regeneron STS is often described as the “Super Bowl” of U.S. high school research competitions, open to U.S. seniors who have completed significant original research.
Imagine a senior who has been working in a university lab on microplastics in local rivers, designing their own methodology and writing a formal research paper. Even without becoming a finalist, the process is rigorous.
What defines STS?
Who is it best for?
Students who enjoy long-term research projects, feel comfortable writing scientific papers, and have support from research mentors or labs.
Regeneron ISEF is the world’s largest international pre-college science fair that requires students to qualify by winning local, regional, and state fairs.
Picture a student designing an app for diagnosing plant diseases. They progress from a school fair to regional competitions, refining their project each time before presenting at ISEF.
How ISEF compares to STS:
ISEF projects can be advanced but focus on practical presentations and interviews.
JSHS encourages original STEM research and emphasizes oral presentations. Students present at regional symposia, with top presenters moving to national competitions.
A typical participant might test the antibacterial properties of local plant extracts, refining a 12-minute presentation.
How JSHS fits:
Judges value solid methodology, reproducibility, and practical applications in recent projects, often tackling real-world issues like climate change or public health. ScholarComp offers resources to help students understand competition expectations.
Olympiad competitions focus on building sophisticated subject knowledge beyond typical school curricula.
Imagine a student mastering molecular biology techniques or complex electrochemistry problems as their “project.”
What these Olympiads emphasize:
The F=ma exam is an entry point into the physics Olympiad, emphasizing mechanics challenges that lead to the USAPhO.
Imagine a tenth grader solving mechanics problems, translating word problems into equations, and developing a deeper understanding of physics concepts.
Time structure: Research competitions require irregular long-term work; Olympiads necessitate consistent practice.
Resources: Research often involves mentorship; Olympiad competitors primarily rely on textbooks and problem banks.
Skills gained: Research fosters experimental design and writing, while Olympiads develop theoretical understanding and test-taking resilience.
Science Olympiad is a well-known K–12 science competition in the U.S., involving a wide range of events across fields like life sciences, physics, and engineering.
Imagine a team of 15 students preparing for regionals, each specializing in different areas from building gliders to testing anatomy knowledge.
What makes Science Olympiad unique?
In Science Olympiad, students who may not excel individually can shine in team roles, such as structural engineering where hands-on skills are crucial.
Recent trends emphasize:
Some major competitions focus heavily on engineering and design. Within events like ISEF or Science Olympiad, there are increased engineering projects.
Imagine a student designing a low-cost water filtration device for a science fair. Judges will evaluate not just functionality but also scalability and impact.
Engineering vs. pure science emphasis:
Projects often focus on sustainability and assistive technology, emphasizing solving real-world problems.
Choose one main competition type as your core focus for the year. This will help prevent burnout.
Engage with teachers, counselors, and mentors about your plans, seeking specific support to enhance your experience.
The world of major science competitions is varied. Research powerhouses like Regeneron STS reward long-term inquiry. Olympiad exams challenge you to master advanced theory. Team arenas like Science Olympiad foster collaboration. Depth, integrity, and authentic engagement with science matter more than merely collecting awards.
Choose competitions that align with your curiosity and goals. Start with a realistic plan, commit to deep learning, and let each competition be a stepping stone to becoming a more capable scientist or engineer. Explore specific competitions with curated overviews and preparation ideas on ScholarComp, and make the most of every challenge.
