The Congressional App Challenge (CAC) is a public effort to encourage kids to learn how to code, through annual district-wide competitions hosted by Members of Congress for their district. Students in participating districts code original applications for the chance to be selected for recognition by their Member of Congress, win prizes, and have their work put on display in the Capitol Building in Washington, DC. The district-wide competitions, now in their third year, take place from July through early November. The CAC is executed by the Congressional staff of each participating district, and coordinated by the Congressional Internet Caucus and the non-governmental sponsor of the project, the Internet Education Foundation.
