The National Honor Society includes students who have proved their dedication to education with their outstanding grades. Initially, a person is required a GPA of 3.5 or higher. This is only available to grades 10, 11, and 12. They must complete another requirement either by essay or an activity sheet. The National Honor Society emphasizes that "Selection to NHS is a privilege, not a right. Students do not apply for membership in the National Honor Society; instead, they provide information to be used by the local selection committee to support their candidacy for membership." In addition to scholarship, there are three other, equally weighted areas in which potential NHS inductees must excel. These are leadership, service, and character. Academically eligible students who are interested in seeking selection into the NHS are expected to participate in activities, both in and out of school, which will enable them to exhibit these elements. According to the National Honor Society Handbook, "Leadership roles in both the school and community may be considered, provided they can be verified... In considering service, the contributions candidate has made to school, classmates, and community, as well as the student's attitude toward service can be reviewed... the society supports and recommends the use of a multi-faceted definition of character known as the `Six Pillars of Character'... A person of character demonstrates the following six qualities: respect, responsibility, trustworthiness, fairness, caring, and citizenship." Each year the Faculty Council reviews the information provided by each candidate, as well as faculty evaluation forms in order to make consistent, equitable selection determinations. An individual interview may be offered in an effort to afford candidates an additional opportunity to provide the Faculty Council with relevant information and clarify any questions that may arise.
