I want to check the plagiarism among the students work. I have student's assignments and looking forward if I can make some settings in Turnitin to test the plagiarism only among student's work. I have simple PDF documents. I am okay to check plagiarism both ways i.e. with the internet sources and among the student's work. But the latter is most important. Also, I do not want to submit the work to the repository. How is this possible? Any help is appreciated. Thanks
As far as I remember (it's about 20 months since I last used Turnitin), the only way Turnitin can check for plagiarism in which the source is another student assignment is if that other student assignment has been placed in the repository. So you can either choose to keep your students' assignments out of the repository, or check for student-to-student copying, but not both.
