This is an invitation for students to compete with their peers by creating and exhibiting an original software application (also known as an “app”). Students may compete as individuals or in teams of up to four, as long as at least two of the teammates reside or attend school in the fifth congressional district.

Middle and high school students are encouraged to register and submit online by November 1, 2021. Click to register and submit your application. Students can also visit the Congressional App Challenge website for more information and view past winners.

The apps will be evaluated by a panel of local judges who work within the academic, software, and entrepreneurial fields. The winning app from each congressional district which hosted a Challenge will be featured on the U.S. House of Representatives’ website ( and displayed in a U.S. Capitol exhibit.
