TJCTF is an international cybersecurity competition hosted by TJCSC, a group of students from Thomas Jefferson High School for Science and Technology in Northern Virginia. The competition consists of a variety of computer science and cybersecurity challenges in an online, jeopardy-style format. You’ll earn points through solving challenges in categories such as binary exploitation, reverse engineering, cryptography, and web. For more information, please join our Discord to learn more about the competition and get notified when the event nears!
That’s awesome—welcome! We have challenges available for players of all experience levels, including those with limited or no programming and cybersecurity experience. You should still be able to learn new things and enjoy the competition without CTF experience. Whether TJCTF is your first CTF or your hundredth, we’re excited to share a variety of challenges for you to dive into!
The competition is open all players, but challenges are aimed towards high school students. Teams are limited to 5 or fewer players. If you need help finding a team, join our Discord to find others in the same boat!

The top team in the Open Division will be awarded $100. All winners will also be awarded Zellic swag.
