The National Honor Society, or NHS, is a nationwide organization in the United States and consists of many chapters in high schools. Selection is based on four criteria: scholarship, leadership, service, and character. The NHS requires some sort of service to the community, school, or other organizations. The projects help students meet the required service hour total monthly. The National Honor Society was founded in 1921 by the National Association of Secondary School Principals. The Alpha chapter of NHS was founded at Fifth Avenue High School by Principal Edward S. Rynearson in Pittsburgh, Penn.
National Honor Society groups are commonly active in community service activities both in the community and at the school. Many chapters maintain a requirement for participation in such service activities. In addition, NHS chapters typically elect officers, who, under the supervision of the chapter adviser, coordinate and manage the chapter as a student organization.
