Welcome to TJSO!

Who We Are

Thomas Jefferson Science Olympiad (TJSO) is a nationally competitive high-school organization, composed of three 15-member teams. We’re the official Science Olympiad team of Thomas Jefferson High School for Science and Technology (TJHSST), a STEM magnet school in Alexandria, Virginia, just outside of DC.

What We Do


Each of our teams compete in 23 events, with topics ranging from electromagnetic waves and ecosystems to cell biology and cryptography. Every team member gets to do 3-4 events.


Each year, TJSO participates in invitational, regional, and state tournaments. If we win the state tournament (as we have done in previous years), TJSO moves on to nationals!


TJSO is built on strong teamwork. Each event is done with at least one partner, requiring close cooperation between teammates. Furthermore, our community strives to support and uplift each individual.

Why We Love TJSO

TJSO wordcloud

“TJSO taught me what it feels like to be part of a team.”

“It’s not everyday that you get to see the green flames of boric acid, the cellular structure of bat hair, or the optical properties of synthetic polymers. These phenomena only come to light at Science Olympiad.”

“Science Olympiad is not only an impetus for building upon your interests, but also a chance to explore new fields of study.”

“I love TJ Science Olympiad because, through it, I’ve gotten the opportunity to explore areas of science we barely touched in class.”

“My favorite aspect about the club is continuing to form a wide net of friends that are super motivated and brilliant, yet also fun to talk to and celebrate with after competition.”

“[TJ Science Olympiad is] the best community of people I’ve ever had the pleasure of being a part of.”

“All the events I studied are not heavily focused [on] in school, so I definitely gained a wider perspective on biology and geology, and ultimately learned more.”

“I couldn’t be more grateful for the memories, knowledge, and experience I’ve gained through my four years of competing on the TJ Science Olympiad team.”

“TJSO is so integral in my life that I can call it my second home and second family – I wouldn’t have enjoyed the TJ student lifestyle if it weren’t for TJSO and the people in it…”

“I’ve discovered that rocks are my life.”

Our Wonderful Sponsors

TJSO would not be what it is without the support of several organizations. We’d like to thank the TJ administration, the TJ Partnership Fund, and the TJ Academic Boosters for all they’ve done and given over the years.

A huge additional thanks to Jane Street Capital for sponsoring our trip to the 2023 Science Olympiad National Tournament in Wichita, KS!
