Referencing prior assignments in a course

[P226mem]

I'd ask your mentor. When I did that class, it was mostly copy and paste the previous assignments into final paper. I reworded and made the transitions better of course. But no, there was no need to cite myself within the same course for what was essentially draft into final. I did not lose any points.  But always ask your mentor to be sure what is wanted.

While you may get away with it, your earlier papers should have been entered into the plagiarism scanner when they were submitted. This means they will be matched against when the plagiarism check is run for any future papers that include the same text. Technically (and by this I mean according to standard academic rules) you are required to cite yourself if you quote from or paraphrase your own work in a later assignment. Yes, it sounds weird, but you can easily Google this to confirm.

They will usually let you off with a warning the first time, but you could see points deducted or a paper rejected for further violations.

If the assignments are part of the same class and they are expecting you to integrate them into the final work, then your instructor will be expecting this and you can disregard the note. But in almost every other case, this can create a problem for you. Particularly once you get into graduate-level courses.

Completely agreeing with the general advice.  But to the specific course SOS110 mentioned by the OP...

In the section of SOS110 that I was in, we had info and lessons on self plagiarism and yes the assignments go through "Safe Assign" (the current plagiarism scanner in use at TESU. 

In my section, the last  paragraph is the case that applies. My mentor said the assignments were drafts of the final paper so we didn't need to do that and it was expected that they were to be part of the final work.   It was not the situation of "self plagiarism" at all where you turn in the same paper in different courses, or graduate work. It was the case of Draft into Final.  so, I don't agree that I "got away with anything".  I know I was terrified of it being self plagiarism but the mentor said no.

again, for the specific of SOS110, ask the mentor if they are drafts and if you need to cite yourself or not. It could vary by mentor if student is writing a draft into final product, or if different assignments. and for the general case, I do agree that a student needs to avoid self plagiarism.
