What is the House App Challenge?

"STEM education provides students the skills they need to compete for the jobs of tomorrow. This competition exposes our students to the STEM fields and inspires them to pursue a future in a rewarding STEM career."
- Congresswoman Dina Titus

The House App Challenge is an academic competition to promote innovation in the fields of science, technology engineering, the arts, and math (STEM). The competition is open to middle school students in the First Congressional District. Participating students will develop or design an app on a platform of their choice. They are also required to submit a video demonstrating the idea, implementation, and impact of the app. Throughout the competition, participating students will have opportunities to engage with various STEM educational partners located in the community to mentor and assist them with the development and design of their app.
