What is a Fiero Code Challenge?

Fiero organizes regular coding competitions for the patrons of our partner schools and libraries. These are free and open to kids ages 8-18 from these schools and libraries.

Inside Fiero’s learn-to-code software, coders will have access to new featured projects with 6-8 weeks to build something awesome. Projects are then submitted for a chance to win code-able robots, drones, Makey Makeys, and more!
