Plagiarism is defined in UNCG's Academic Integrity Policy as follows:
Plagiarism: Representing the words of another as one's own in any academic exercise. Plagiarism may occur on any paper, report, or other work submitted to fulfill course requirements. This includes submitting work done by another, whether a commercial or non-commercial enterprise, including web sites, as one's own work.
a. Failure to cite references: includes intentional or obvious failures to properly cite sources.
b. Submitting, as one's own, work done by or copied from another: includes work done by a fellow student, work done by a previous student, or work done by anyone other than the student responsible for the assignment.
UNCG takes plagiarism very seriously. A student who is found guilty of plagiarism can receive a penalty ranging from having to re-do the assignment to failure of the assignment or course, and even expulsion from the university.
So it's essential that you as a student understand what plagiarism is and how to avoid it.
