does not offer an academic minor, the certificates effectively serve as one. Course structure is determined by the instructor and department. Classes vary in their format, ranging from small seminars to medium-sized lecture courses to large lecture courses. The latter two typically have precepts, which are extra weekly discussion sessions that are led by either the professor or a graduate student. The average class meeting time is 3–4 hours a week, although this can vary depending on the course. The student to faculty ratio is 5 to 1, and a majority of classes have fewer than 20 students. In the Fiske Guide to Colleges, academic culture is considered as "tight-knit, extremely hardworking, highly cooperative, and supportive." Undergraduates agree to adhere to an academic integrity policy called the Honor Code. Under the Honor Code, faculty do not proctor examinations; instead, the students proctor one another and must report any suspected violation to an Honor Committee made up of undergraduates. The Committee investigates reported violations and holds a hearing if it is warranted. An acquittal at such a hearing results in the destruction of all records of the hearing; a conviction results in the student's suspension or expulsion. Violations pertaining to all other academic work fall under the jurisdiction of the Faculty-Student Committee on Discipline. Undergraduates are expected to sign a pledge on their written work affirming that they have not plagiarized the work. Grade deflation policy The first focus on issues of grade inflation by the Princeton administration began in 1998 when a university report was released showcasing a steady rise in undergraduate grades from 1973 to 1997. Subsequent reports and discussion from the report culminated to when in 2004, Nancy Weiss Malkiel, the dean of the college, implemented a grade deflation policy to address the findings. Malkiel's reason for the policy was that an A was becoming devalued as a larger percentage of the student body received one. Following its introduction, the number of A's and average GPA on campus dropped, although A's and B's were still the most frequent grades awarded. The policy received mixed approval from both faculty and students when first instituted. Criticism for grade deflation continued through the years, with students alleging negative effects like increased competition and lack of willingness to choose challenging classes. Other criticism included job market and graduate school prospects, although Malkiel responded by saying that she sent 3,000 letters to numerous
