National Geographic Education has been implementing teacher professional development programs for the past 25 years in support of their overarching mission to inspire people to care about the planet, and to prepare teachers to inspire their students. The long-term mission of National Geographic Education is to build a geo-literate society—a society prepared to make critical 21st century decisions about places near and far. To that end, their resources and programs for teachers and students are developed with the goal of leading to meaningful changes in understanding about wide-ranging topics in geography, social studies, and science and students' roles as citizens of the world. National Geographic Education’s commitment to teacher professional development supports educators by preparing them to teach effectively in STEM disciplines and about decision-making as part of preparing students to be geo-literate individuals.
