Design-and-build challenges open to students in grades 9 to 12, from rocketry and robotics to bridge design and invention. Most run as teams through a school club, and several are free or close to it once you account for grants.
Start with something rated 1 or 2 out of 5 for difficulty on this page. Those assume no prior competition experience and usually publish past problems or past winning entries so you know exactly what you are walking into.
6 of the 20 listed here have no entry fee for the student. Note that a free entry fee is not the same as a free competition: team-based events can carry materials and travel costs, which each listing states separately.
