The National Honor Society (NHS) is committed to recognizing students for their outstanding academic achievement, service, leadership, and character while providing programs and services that promote their development into exemplary role models. Since its inception in 1921, NHS has been a pioneer among student organizations in the United States by using a unique, forward-thinking lens to recognize students for far more than academia. As we look to the future, NHS will continue to push the boundaries of student development, serving as the champion of student growth and achievement for the entire learning community. NHS will mark its centennial anniversary on March 1, 2021—and this centennial celebration tool kit can help in planning activities and getting the word out to your community.
