HMC proctors have similar responsibilities to R.A.s at other colleges, but have no major "rule enforcement" role. Instead, given Mudd's strongly held honor code and highly responsible students, proctors' "rule" duties center on reminding irresponsible residents of their obligations under the honor code.

Proctors are seniors, chosen during the spring of their junior year. Taking on roles of personal and academic counselors, crisis intervention specialists, roommate mediators, student advocates, patient listeners, ombudspeople, social and educational programmers, and medical and disaster first responders, they work closely with Guy Gerbick, associate dean of students/dean of residential life, to respond to individual students' concerns. They also work with dorm presidents to find solutions to dorm problems. There is one proctor for each Quad dorm, Linde and Sontag, with two in Case and two in Atwood.

A proctor is on-call at all times—24/7—during the academic year. Should you need assistance, contact your proctor at his/her home number first (proctor schedules are posted in each dorm and in the window of the DOS/Registrar's lobby in Platt). If there is no answer, call the proctor via X79911, which will forward the call to the proctor on-call’s cell phone. To call the phone directly, you can dial (909) 717-7183.

In an emergency situation, Campus Safety should be called first at x72000. They can contact the proctor on-call, as well as the dean on-call and other on-call staff from the Monsour Counseling Center and Student Health Service. During weekdays, you can call the Dean of Students Office about crisis situations at X18125, or (909) 621-8125 from off campus, from 8 a.m. to 5 p.m.
