According to the NHS/NJHS website, the National Junior Honor Society (NJHS) was established in 1929 and is the nation's premier organization established to recognize outstanding middle level students. More than just an honor roll, NJHS serves to recognize those students who have demonstrated excellence in the areas of Scholarship, Leadership, Service, Character, and Citizenship. These characteristics have been associated with membership in the organization since its establishment.

Today, it is estimated that more than one million students participate in activities of the NHS (High School) and NJHS (Middle School). NHS and NJHS chapters are found in all 50 states, the District of Columbia, Puerto Rico, many U.S. Territories, and Canada. Chapter membership not only recognizes students for their accomplishments, but challenges them to develop further through active involvement in school activities and community service.
