Cheating on examinations; plagiarism; unauthorized sharing of materials, answers, or sources; improper acknowledgment of sources in essays; the use of a single essay in more than one course except in academically appropriate circumstances and with the prior explicit permission of the instructors; other means by which a student may create, submit, or take credit for work that is not the student's own; and not following exam or assignment procedures and other means by which a student may compromise the integrity of exams or assignments. (See Academic Integrity.)

Physical restriction, assault, or any other act of violence or use of physical force against any member of the community, or any act that threatens the use of violence or physical force. The implied or express consent of the person against whom such violence or force is used will not be considered a defense.

U. Violation of the regulations on alcohol or social functions

Violation of the regulations on social functions or the Yale College regulations on alcoholic beverages. (See Activities and Events and Alcohol.)

V. Hazing

Because it violates our community values and standards, Yale College prohibits all acts of hazing. Hazing includes any action that violates Connecticut hazing law (CT General Statute, Section 53-23a, Hazing) as well as additional violations spelled out in these regulations.

In addition to Connecticut law, Yale College defines hazing to include initiation or affiliation activities that intentionally or recklessly endanger physical or mental health; that intimidate, denigrate, or humiliate persons pledging or seeking membership, or seeking to retain membership, in a registered or unregistered student organization or on an athletic team; or that intimidate, denigrate, or humiliate third parties who are witness to or subject to such activities. Blindfolding or physically restraining another individual, with or without that person's consent, falls within the Yale College definition of hazing.

Hazing is an offense whether it occurs on or off campus. The Executive Committee will not consider the implied or express consent of the person being hazed as a defense; nor will it consider the use of alcohol or drugs as a mitigating factor. To the contrary, in the context of hazing, the use of alcohol or drugs by any participants may be considered an express attempt to impair judgment, likely contributing to reckless behavior. Because hazing is an organizational activity, the organization, its officers, and responsible members will be held accountable for hazing violations.

Where harm occurs or the potential for harm exists to any person or persons as a result of hazing by members of a student group, the hosts of the event as well as the individuals directly involved and the officers of the organization (or their equivalent) can be held personally responsible. With respect to possible disciplinary action against all such persons, the Executive Committee may consider as mitigating factors their efforts to prevent the harmful or potentially harmful situation, as well as their cooperation with the Executive Committee’s investigation of the situation.

Student organizations include but are not limited to athletic clubs, varsity teams, fraternities, sororities, musical groups, junior and senior societies, drama groups, comedy groups, political groups, cultural houses, tour guides, student government organizations, and residential colleges.

W. Special provisions concerning student organizations

1. Conduct Off Campus. Conduct occurring off campus is a violation of these regulations if the conduct, had it occurred on campus, would be a violation of section C, “Acts of violence or physical force,” section D, “Sexual misconduct, including sexual harassment,” section L, “Alcohol,” or section M, “Drugs.” In addition, as provided in General Conduct and Discipline, any conduct occurring off campus that imperils the integrity and values of the University community may result in disciplinary action.
2. Responsibility for Events. If any violations of sections L, “Alcohol,” or M, “Drugs,” occur at an event, or in connection with an event, where alcohol is served or permitted to be consumed, and which is held, sponsored, or supported by a fraternity or other registered or unregistered student organization (either on campus or off campus under the circumstances specified in subsection above), and the individual or individuals directly responsible for the violations are not identified, the host or hosts of the event or the organization responsible for the event will be held responsible for the violations. If the hosts are also not identified, the officers of the organization will be held personally responsible for the violations. The Executive Committee may consider the efforts made by the hosts or officers to prevent such violations, and their cooperation with the investigation of the violations, as mitigating factors with respect to the penalty for the violations.
