What Percentage Of Plagiarism Is Acceptable?

Academic institutions consider any plagiarism percentage beyond 15% to be a cause for serious concern. A score of 20% and over is alarming, as this indicates deliberate attempts by the student to deceive their instructor through plagiarizing text material. Such acts are punishable offenses that can have far-reaching consequences in terms of academic integrity.

What Percentage Of Plagiarism Is Acceptable?

As we begin a new academic year or semester, it is essential to review plagiarism policies with students. Penalties for non-compliance can vary drastically and may include drastic measures such as expulsion; however, having an understanding of the potential consequences could act as a deterrent before turning to unscrupulous methods.

To further prevent these practices, try avoiding repeating projects from previous years’ curriculums in order to minimize familiarity amongst peers – consider allowing students access to online originality checking tools prior to submitting works, which would enable them verify that their assignments meet established benchmarks without sacrificing integrity along the way.
