Congressional App Challenge

Each year, the U.S. House of Representatives hosts the Congressional App Challenge. This is an annual coding competition designed to encourage middle school and high school student participation in computer science and coding, regardless of experience. It is an opportunity for students to compete against other peers within their district by creating an original application in a variety of programming languages and on different platforms.
