2021-22 UPDATE: National Geographic has made the decision to permanently discontinue the National Geographic GeoBee to make way for new, transformative, and innovative geography education opportunities in which students around the globe can more equitably participate.
Each year thousands of schools in the United States participate in the National Geographic Bee using materials prepared by the National Geographic Society. The contest is designed to encourage teachers to include geography in their classrooms, spark student interest in the subject, and increase public awareness about geography. Schools with students in grades four through eight are eligible for this entertaining and challenging test of geographic knowledge.
