The Challenge is a competition and program that celebrates and elevates the science of chemistry to inspire on-going study and careers.

Program Overview

The Challenge is a multilevel individual competition, that begins with participants completing the Challenge Qualifier at their schools. The Qualifier is a short multiple-choice test provided by CEF and administered by educators. Top Qualifier scorers from each school then advance to the next level of competition a Local or Local-as-State Challenge.

At the Local and State Challenges participants answer several rounds of multiple choice questions. Students participate individually in the Challenge competitions. The students who score the highest will move on to the next level of competition (as noted in the chart below) with the top participant from each state advancing to the National Challenge!
