Plagiarism or Similarity
At this time of year, we hear a lot of chatter from students via Twitter (follow us: @turnitin) saying, "turnitin says my essay was 23% plagiarized," or "just submitted my paper to turnitin... 4% plagiarism is good right?," or "my Turnitin plagiarism percentage is only 18%."
There is a very distinct difference between what Turnitin flags as matching text (aka: similarity index) and plagiarism. Turnitin will highlight ANY matching material in a paper—even if it is properly quoted and cited. Just because it appears as unoriginal does not mean it is plagiarized; it just means that the material matches something in the Turnitin databases.


In response to states' adoption of the Common Core State Standards (CCSS), Turnitin will be releasing CCSS-aligned writing rubrics for grades 9-10 and 11-12. There will be a total of 6 rubrics altogether (2 each for Informative, Argumentative, and Narrative text types). These rubrics were developed for Turnitin by the English Professional Learning Council, a group of educators sponsored by and involving instructors primarily from Saddleback College and the Orange County Department of Education.
Many Turnitin users that have access to GradeMark are not aware of what an essential, powerful and effective tool it can be.
