As a part of the National Geographic Education and Children’s Media division, National Geographic Education focuses on working closely with and creating materials for educators and schools that bring the Society's spirit of exploration and adventure to our goal of educating young people about their world. 

To be effective in the modern world, young people will need to be able to thrive in diverse workplaces and respond to fast-changing circumstances. To act responsibly, they will need to understand how our interconnected world works so they can make informed decisions. These are the same qualities exemplified by National Geographic explorers for more than 125 years. For that reason, our work is aligned to a learning framework that defines the attitudes, skills, and knowledge of an explorer. 

Educators and learners can find and explore all materials created by National Geographic Education here, at NatGeoEd.org. With over one million visitors each month, the award-winning NG Education website is recognized as one of the most innovative sources for educational and reference content.
