Additional Major Rules


Respect for the rights of all and for the differences among us is essential for the health of the Deerfield community. Discrimination against others on the basis of race, color, ethnicity, national origin, religion, sex, sexual orientation, gender identity and/or expression, age, ancestry, genetic information, marital status, place of birth or on the basis of disability has no place here. If members of the Deerfield community experience or witness any apparent incident of discrimination by students or employees, they should report the incident to an employee or the the Student Life Office. Such incidents violate the ideals of Deerfield and may be subject to appropriate disciplinary response.

Online Behavior, Devices, and Privacy

Students are subject to the Academy’s rules—and potential disciplinary response—for both offline and online activities. We recommend that students manage their online privacy settings carefully and review the Academy’s Acceptable Use Policy.

We require that students:

  • Never impersonate or adopt another person’s identity or under another user’s account or identity.
  • Never post anonymously.
  • Don’t post sensitive information: ID numbers, addresses, birthdates, or other details that could enable identity theft or put you or your friends at risk.
  • Report online bullying or harassing behavior to the Dean of Students immediately.
  • Ask permission to record classes, meetings, or private conversations.


Theft —including using others’ possessions without explicit prior permission— is a major rule violation at Deerfield.Students must be clear on this standard and recognize that the unauthorized use of someone else’s information (including login credentials), clothes, bicycle, etc. is considered to be theft.

Open Flame, Fire Safety Equipment

The burning of anything, including but not limited to tobacco products, incense, or candles poses a serious risk to all occupants of the building and is prohibited. Open flame, including the lighting of matches or lighters, in any building, except under the supervision of faculty or staff, is also prohibited. Inappropriate use of fire extinguishers, emergency lights, smoke or heat detectors or fire alarms presents a significant safety risk and will be considered a disciplinary matter.

Students are not permitted to possess gas grills on campus. The use of charcoal grills requires employee permission.


Firearms, weapons (including knives), ammunition, fireworks or other explosives are prohibited.

Keys, Unauthorized Access

Unauthorized entry or the unauthorized use or possession of an Academy key or keycard is forbidden. Propping of locked doors to provide unauthorized access is prohibited.

Out of a concern for security, students should take care to protect and keep track of keys. Students who lose their room key will be assessed 7 Accountability Points and charged $50.00 for replacement. Students who repeatedly place calls to Security for lockouts will be assessed 2 Accountability Points for each call. Seniors who do not return their keys at the end of the year will be charged $100.00. Returning students who do not return their key at the end of the year will have 7 APs carry over into the following year.

Repeated Failure to Meet Obligations & Expectations

Students who repeatedly miss school commitments or display behavior disrespectful and unbecoming of the Academy may face disciplinary action up to and including dismissal. When a student’s general citizenship and demeanor repeatedly fall below the Academy’s expectations, a faculty review may result in a recommendation to the Head of School, Assistant Head of School for Student Life or Dean of Students for disciplinary response, up to and including suspension or dismissal.

A continued accumulation of minor infractions or incidents of personal misconduct – including the accumulation of Accountability Points – may also be considered a violation of a major school rule.
