Registration for participants has closed! Participants must be current high school students. Computer science and engineering experience is not necessary, as we'll have workshops and mentors so you can learn. Please note that registering alone does not guarantee you will receive a ticket. Admission decisions will be made based on a variety of factors including the date/time you register.

Judges must be present during the entire judging process (5:00 p.m. to 7:30 p.m. on Sunday), but not necessarily during the entire hackathon. Computer science and engineering experience is preferred but not required.

Mentors help students if they have any technical questions, and don't have to be present online the entire time. Computer science and engineering experience is required.



What is HackTJ?
HackTJ is a student-run hackathon where you will have 24 hours to learn how to code and/or work with your friends to make your idea come to life.
When is HackTJ?
HackTJ will start on Saturday, April 10 and run until Sunday, April 11.
Who can attend?
HackTJ is open to any and all current high school students. If you're not a high school student but would like to attend, consider coming as a judge, mentor, or volunteer.
Is there any cost?
Nope! Thanks to our sponsors, HackTJ is completely free!
Is there a deadline?

Registration for participants, judges, mentors, and volunteers opens on Monday, February 22 at 8:00 PM.

Registration for participants closes on Friday, March 26 at 8:00 PM—this is a hard deadline; we do not accept submissions after this time.

Judges, mentors, and volunteers will be able to register until the start of the event.

Do you have a code of conduct?
Yes, good question! We have adopted the MLH code of conduct, which all attendees will be required to adhere to.
Isn't hacking illegal?
In the context of a hackathon, "hacking" is to build a real application over the length of the event. It's important to not confuse this with illegal hacking, which is gaining unauthorized access to a computer.
Do I need a team?
If you already have a team of 2-4 people you want to work with, that's awesome! If not don't worry because we'll have an opportunity for people to join a team if they need one.
What if I don't know how to code?
Come to HackTJ! Coding is fun, creative, and an important skill, and HackTJ is the perfect way to learn. We'll have workshops and mentors to help guide you.

  • Overall Hack
