An academic honor code or honor system in the United States is a set of rules or ethical principles governing an academic community based on ideals that define what constitutes honorable behaviour within that community. The use of an honor code depends on the notion that people (at least within the community) can be trusted to act honorably. Those who are in violation of the honor code can be subject to various sanctions, including expulsion from the institution. or in other words, honor code is like a pledge taken by students to the effect that they will uphold academic integrity and ethical behavior and will not engage in any kind of cheating, stealing, and misrepresentation. One of the first such codes was created at the College of William & Mary in the early 18th Century. US military service academies Presently, some of the most notable and most stringent honor codes exist at the Federal Service Academies and Senior Military Colleges. The military academy honor codes not only govern the cadets and midshipmen's lives at the academies but also are deemed essential to the development of military officers who are worthy of the public trust. As such, the codes are not limited merely to academic situations or to conduct on campus; cadets and midshipmen are expected to live by the codes' ethical standards at all times. The codes are as old as the academies themselves and simply state that cadets and midshipmen do not lie, cheat or steal, nor tolerate those who do. A single-sanction Honor Code, in which any offense results in expulsion regardless of severity, exists at Virginia Military Institute, which features a "drum out" ceremony which is still carried out upon a cadet's dismissal. Outside of the military, Washington and Lee University and the University of Virginia also have single sanction codes. At three of the service academies and at Virginia Military Institute, anyone who learns of an honor code violation is required to report it. Failure to do so is considered "toleration," which itself violates the code. That also holds true at schools with combined cadet and traditional student programs, such as Norwich University, Texas A&M, and The Citadel, whose honor codes specifically provide that all students, both cadets and civilians, do not "tolerate those who do." It is notable that the three Senior Military Colleges have two honor codes, one for cadets and one for civilians,
