The Honor System and the School of Engineering and Applied Science

The School of Engineering and Applied Science relies upon and cherishes its community of trust. We firmly endorse, uphold, and embrace the University’s Honor principle that students will not lie, cheat, or steal, and we expect all students to take responsibility for the System and the privileges that it provides. We recognize that even one Honor infraction can destroy an exemplary reputation that has taken years to build. Acting in a manner consistent with the principles of Honor will benefit every member of the community both while enrolled in the Engineering School and in the future.

 If you have questions about your Honor System or would like to report suspicions of an Honor offense, please contact Justin Starr (jstarr@virginia.edu) or Alison Tramba (avtramba@virginia.edu).
