Additional Major Rules

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 send, solicit, or share nude or compromising photos or content.
  • Never impersonate or adopt another person’s identity or gain access under another user’s account or identity.
  • Never post anonymously.
  • Never post sensitive information: ID numbers, addresses, birthdates, or other details that could enable identity theft or put people at risk.
  • Report online bullying or harassing behavior to a Designated School Official (DSO) immediately.
  • Ask permission to record classes, meetings, or private conversations.

Students should recognize that community members have varying degrees of comfort with their words and images being captured and/or posted online; they should consider others’ privacy and exercise discretion when recording and sharing material. In this vein, wearable computing devices, hidden cameras, and other devices designed for surreptitious recording are prohibited. Students operating remotely controlled or automated cameras (e.g. GoPros, helicopters, timelapses, etc.) should exercise special care to protect the privacy of others. Drones may only be used with explicit permission from a member of the Student Life Office, obtained at least 24 hours in advance.


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, scooter, etc. is considered theft.

Open Flame, Fire Safety Equipment

The burning of anything (tobacco products, incense, candles, etc.) poses a serious risk to all occupants of a building and is prohibited. Open flame, including the lighting of matches or lighters, in any building, except under the supervision of an employee, 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 storage and use of charcoal grills require employee permission and supervision.


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

Keys, Keycards, 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.

To ensure the security of dormitories and other shared spaces, OneCards must be deactivated immediately (via DAinfo) if lost or stolen. Replacement cards can be procured from the Finance Office or Security Office; there is a $10 fee for replacement, but no Accountability Points are assessed.

Out of a concern for security and safety, students should take care to protect and keep track of keys. Those who lose their room keys will be assessed seven Accountability Points and charged $50.00 for replacement. Students who place repeated calls to Security for lockouts will be assessed two 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 seven APs added to their spring term totals, and any resulting Sanctions will be served the following fall.

Fake IDs

False forms of identification and the use of others’ identification with an intention to deceive are prohibited.

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.
