Congressional App Challenge

The Congressional App Challenge invites middle- and high-school students to create a functioning app on any topic, using any programming language or platform, and submit it in a participating congressional district. Students may compete alone or in teams of up to four, and district winners can have their work displayed in the U.S. Capitol and on House.gov and be invited to the #HouseOfCode celebration. In the 2025 cycle, 394 congressional offices participated, 13,830 students registered, and students submitted a record 4,650 functioning apps. The program generally launches in spring and closes in the fall.
