2020 Congressional App Challenge

Thank you for your interest in the Congressional App Challenge! 

The Congressional App Challenge (CAC) is an annual competition designed to encourage student participation in computer science and coding. This year, students are encouraged to register online by Sept 10th before submitting their app by October 19th.

Officially launched by the U.S. House of Representatives in 2015, this nationwide effort allows students to compete against their peers by creating an application (also known as an “app”) for desktop/PC, web, tablet, mobile, raspberry Pi or other devices. Any programming language, such as C, C++, Java, JavaScript, Python, Ruby, or "block code" is acceptable. The Challenge is designed to promote innovation and engagement in computer science.

The Congressional App Challenge is open to all middle and high school students in the 4th Congressional District of Oregon. Students entering the competition must submit their app through the App Challenge website at before the October 19th deadline. 

The winner from the 4th Congressional District, chosen by a panel of expert judges, will be featured on as well as the digital display located in the cannon tunnel to the U.S. Capitol, honoring the winners from across the country.
