Direct answer
Using Turnitin with a class ID means joining your instructor's private class and submitting assignments through its inbox, where every paper is checked for similarity and AI writing. The class ID and enrollment key are the credentials your instructor issues so that your submission lands in the correct assignment and produces the report they will review [1]. Once you understand where these credentials come from and how the enrollment flow works, submitting becomes a straightforward, repeatable process [1].

Once you understand where these credentials come from and how the enrollment flow works, submitting becomes a straightforward, repeatable process [1].
Where Do You Find Your Turnitin Class ID And Enrollment Key?
Your instructor is the only source of your Class ID and enrollment key, so check the places they normally share course information: the course syllabus, the announcement feed, an email, or the assignment page in your learning management system [2]. The Class ID is a numeric identifier for the instructor's Turnitin course, and the enrollment key is the password-like code that keeps the class private to enrolled students.
If the credentials are not visible, email your instructor and ask for the Class ID and enrollment key directly — there is no way to look them up on your own, because Turnitin does not expose other users' class details [2]. Keep both values together until you have completed enrollment, since the enrollment screen requires them at the same time.
Once you enroll, your account is linked to the instructor's class, and any paper you submit through that class generates the similarity report and the AI writing report that the instructor sees in the assignment inbox [2]. That is why the class ID matters beyond enrollment: it determines which report your instructor can open when grading.
How Do You Enroll In A Turnitin Class And Submit An Assignment?
Sign in to your Turnitin account at turnitin.com, open the enrollment screen, and enter the Class ID and enrollment key exactly as your instructor provided them — both fields are case-sensitive and must be entered without extra spaces [3]. After enrollment succeeds, the class appears on your dashboard with its assignments listed, and you can open the correct assignment to upload your file.
When you submit, choose the paper file (.docx,.pdf, or.txt are typical) and confirm the submission; Turnitin then generates the similarity report and the AI writing indicator that appear on your submission record [3]. Many instructors configure the assignment so that the report is generated at the due date rather than instantly, so check the assignment instructions to understand when your results become visible.
Before you submit, it is worth verifying that the file you upload is the final version, because the report is tied to that submission and re-uploading may be restricted depending on how the instructor set up the assignment [3]. If you want certainty about your score before it reaches the instructor, run your own check first so the first submission is already clean.
Can You Check Your Own Turnitin AI And Similarity Report Before Your Instructor Does?
Yes — and it is one of the smartest habits before any Turnitin submission. Students can run their own Turnitin check on a draft and see the same AI writing and similarity results that the instructor will review, which turns submission from a gamble into a preview [4].
Checking first matters because the AI writing report is generated by the same detector regardless of who runs it: the score on your preview will match what the instructor's class report shows for the same text. Instructors are also encouraged to discuss AI writing results openly with students rather than treat the report as a verdict, which means showing up with a clean, explainable report gives you a much stronger position in that conversation [4].
The practical workflow is simple: check your draft with a Turnitin report service, review the similarity matches and the AI writing percentage, revise any flagged sections, and only then submit through your class ID. This way the report your instructor opens reflects the work you want them to see, not the version you were still unsure about [4].
Getting the class ID and enrollment key right is only half the battle — knowing what your Turnitin report will show before your instructor opens it is what protects your grade. turnitin0 runs the real Turnitin AI writing and similarity checks on your draft and delivers the exact report format your professor sees, so you can fix flagged sections and re-check until the report is clean before you submit through your class.
