Officially launched in 2015, this competition is a nationwide event intended to engage students’ creativity and encourage their participation in STEM fields. This competition allows students to compete with peers in their own district by creating and exhibiting their software application (AKA Apps) for web, PC, tablet, mobile, raspberry Pi or other platform of their choice. We accept any programming language, such as C, C++, Java, JavaScript, Python, Ruby, "block code", etc.

Students may compete as individuals or in teams of up to four, provided at least two of the teammates are from our district. The 2022 Congressional App Challenge is OPEN, and eligible students can register for the competition now. The deadline to apply is November 1, 2022.

The apps will be evaluated by a panel of local judges who work within the academic, software and entrepreneurial fields.
