The nonprofit National Ski Patrol (NSP) is the largest winter education organization in the world. The NSP provides education, outreach, and credentialing related to outdoor recreation and safety. It is currently composed of more than 31,000 members who serve in over 650 patrols. NSP members, both volunteer and paid, ensure the safety of outdoor recreation enthusiasts in ski areas throughout the United States of America and certain military areas of Europe. For its dedication to the promotion of public safety in skiing and other winter sports, the group was granted a congressional charter under Title 36 of the United States Code in 1980.
