When and whether students have access to their own Originality Check reports is at the discretion of faculty. If a faculty member allows students to review their own Originality Check reports, they may allow this either at the time an assignment is submitted, or after grades have been released. If a faculty member has allowed students to review their own Originality Check reports, students can do so in the course Grades area (even if the assignment has not yet been graded).
For detailed instructions on configuring Turnitin to allow or disallow students from seeing their own Originality Check report, visit the help document titled "As an Instructor, how do I enable and configure Turnitin in bCourses?"
