According to the CHS Academic Dishonesty Policy, plagiarism is "both a form of theft and of lying. It is the act of utilizing another person's work or ideas but representing them as one's own. Plagiarism may involve something as small as taking a sentence from a book and copying it without citing the source, or as substantial as using an online paper mill to obtain complete research papers."
