The National Honor Society (NHS) is the nation’s premier organization established to recognize outstanding high school students. More than just an honor roll, NHS serves to honor those students who have demonstrated excellence in the areas of Scholarship, Leadership, Service and Character. These characteristics have been associated with membership in the organization since their beginnings in 1921. Today, it is estimated that more than one million students participate in activities of the NHS. NHS 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.
The National Honor Society is a select organization available to students by invitation only. To receive an invitation, a student must be an upperclassmen in good standing with Garces Memorial and have a cumulative GPA of 4.45 or higher to apply.  The application process requires students to complete an application, write an essay, and submit three teacher recommendations.  The applicant information is presented to a selection committee for review.  The selection committee is not supplied with the names of the applicants.  Student anonymity ensures impartiality and a fair selection process. If accepted, the student is notified and attends a formal induction ceremony.
During the school year, the members meet on a regular basis to develop and execute a community service project.
In addition to the honor of being a member of a prestigious group, the members wear a National Honors Society stole over their gowns at both the Baccalaureate Mass and the Garces Commencement Ceremonies.
