Self Plagiarism

Self-plagiarism is possible and it's just as serious.

Self-plagiarism, or "double-dipping," is deception and goes against the core principles of ethical writing. Papers are assigned for you to demonstrate what you have learned in a particular class. If you reuse a paper you wrote for a previous class, you are not demonstrating new learning.

Examples of self-plagiarism:

  • Turning in a paper for a current class that you already submitted as an assignment for a previous class
  • Using a substantial amount of a paper written for another course as content for a new assignment
  • Treating anything you've previously written as if it were new material
