The penalties for academic misconduct are severe, and can include dismissal from the University. All students at Indiana University are responsible for knowing the rules governing academic conduct. These rules are set out in the Code of Student Rights, Responsibilities, and Conduct. There are specific implementation procedures for the Bloomington campus (click on "Disciplinary Procedures," then "Academic Misconduct"). The rules about academic honesty are important for everyone, but students who are new to the education system in the United States should be especially sure to read and understand them because the expectations here may be different from those they are accustomed to.
In general, it is assumed that all academic work, including papers, essays, quizzes, tests, oral reports, projects, and performances, is a student's original work. Collaboration is sometimes permitted for certain assignments in some courses. You should always make certain that you understand what a professor expects for a particular assignment; if you are unsure, ask.
It is also assumed that material borrowed or quoted from other sources (including from books, articles, the Web and elsewhere) will be acknowledged and cited. IU's Writing Tutorial Services has a brief but useful page about plagiarism available.
Students with questions about the rules are welcome to ask the graduate academic advisor or the director of graduate studies.
