Rules of Thumb: Ask yourself before answering each test question
- Is there word-for-word plagiarism anywhere in the student version? If yes, select "Word-for-Word plagiarism." You're done with that question.
- If there is no word-for-word plagiarism, is there paraphrasing plagiarism anywhere in the student version? If yes, select "Paraphrasing plagiarism." You're done with that question.
- If there is no word-for-word and no paraphrasing plagiarism anywhere in the student version, then select "This is not plagiarism."

Plagiarism Test Clues
- Some examples will include both word-for-word plagiarism and paraphrasing plagiarism. If both kinds of plagiarism are present, you must choose word-for-word for a correct answer. You would choose this if you follow in order the rules of thumb above.
- Sneaky plagiarism is the hardest kind to detect. See examples of such patterns.
We have seen students do this in their writing. In some places, they will paraphrase correctly, quote correctly, and cite correctly, but in other places they also include a string of 7 or more words in sequence taken from the source, or paraphrase without citation. This is still word-for-word plagiarism, if quotation marks are missing or the full in-text citation is missing which must include a specific locator (e.g., page number); or it is paraphrasing plagiarism if ideas in the source are used without clear attribution by proper citation.
If the reference is missing, it is still plagiarism even if the in-text citation is correct. Nothing can be missing that is needed to avoid plagiarism, according to the criteria in the table above.
Some test takers might claim that these are "trick questions." Nonetheless, plagiarism is still plagiarism, even if disguised this way.
- To avoid paraphrasing plagiarism: In a paragraph which summarizes someone else's ideas, the citation should occur in the sentence which begins the paraphrase. When done appropriately this way, the citation signals the reader when the paraphrase is starting. Paraphrased sentences that immediately follow need not be cited individually, as long as it is clear in each subsequent sentence whose ideas are whose. See also the discussion here.
- Some people may believe that the "seven-words-in-a-row" criterion we use is too strict. Others may think it is too lenient (e.g., more than 3 words in a row from the source is word-for-word plagiarism).
- There should be no test question for which the right answer depends on determining if the idea taken from the original source material qualifies as "common knowledge."
