Factors that Determine How much Turnitin Similarity is too much
Before we finalize what is acceptable Turnitin similarity score, we have to find out what Turnitin actually checks in our paper. Turnitin provides various options to the instructor while creating a class for checking Turnitin score.
These options determine Turnitin originality report acceptable percentage.
Question 1: Exclude bibliographic materials from Similarity Index for all papers in this assignment?
The instructor can either select yes or no. This setting allows the instructor to choose to exclude text appearing in the bibliography, works cited, or references sections of a student paper from being checked for matches while generating Similarity Reports.
If the instructor has selected the yes option, the Turnitin acceptable plagiarism score should be increased by the instructor. It is because there is more likely a chance that students unknowingly get online data from similar sources. You should ask your instructor about this feature.
Turnitin will show plagiarism for the text appearing in the bibliography, works cited, or references sections even students have not copied from each other. That’s why the instructor will increase the acceptable Turnitin similarity score.
Question 2: Exclude Quoted Materials from Similarity Index for all Papers in this Assignment?
The instructor can either select yes or no. This setting allows the instructor to choose to exclude text appearing in the quotes from being checked for matches while generating Similarity Reports.
If the instructor has selected no, the acceptable Turnitin score will be high. There is more chance to get plagiarism or high turnitin score if everyone is writing on the same topic. Same topics will use similar terms and Turnitin will consider it plagiarism if three words match in a single line.
The instructor should exclude the quoted materials from the acceptable turnitin percentage if all students are working on same topic. Otherwise, the ideal acceptable Turnitin score should be high.
Question 3: Exclude Small Sources?
The instructor can either select yes or no. This setting allows the instructor to choose to exclude sources that are not sufficient length (determined by the instructor) from being considered while generating Similarity Reports.
Note: The instructor can override all above options in individual Similarity Reports as well.
We have made a test to analyze the impact of all the above options and you will be astonished to see how much plagiarism these factors were including. You can see from the below picture that the total Turnitin plagiarism score is 45%.
