When a student submission has a 0% similarity score, it signifies that none of the text in the paper matches any of the enabled search sources. Shorter papers (1-2 pages) and creative writing tasks in which students use their own words/voice are more likely to receive a 0 percent score. Longer essays and research papers are less likely to be accepted with no match.
Turnitin's search engines include commercial databases as well as university and other accredited institutions' collections. Students should know that submissions with no results may not always be rejected immediately. Instead, Turnitin sends an email notification when someone requests the file(s) you submitted. If you fail to respond to this notification, your submission may be retained by Turnitin indefinitely.
If you want your submission removed from Turnitin's database, you will need to contact them directly and explain what action you would like taken. Some universities may have access to special tools for purging files from their search engines; others may require you to submit a request via e-mail.
In addition to removing files permanently, some actions can also result in suspensions or full withdrawals of access to campus computing resources. For example, if you repeatedly submit documents with low quality scores, your profile may be blocked from accessing the library system entirely. Similarly, if you continually turn in incomplete assignments, you could be prevented from completing future assignments or exams.
If a student's submission obtains a 0 percent score, the teacher may be employing assignment parameters that result in a lower similarity score. For example, if the student had specified $10,000 in damage and the teacher assigned $15,000 worth of damage, there would be no match because the amount is not similar enough. A score of 100% means that all of the words or phrases in the student submission matched one of the sources.
Similarity scores are based on the percentage of word-for-word exact matches between your assignment and an enabled source. For example, if you copied part of your assignment and pasted it into a new document, the similarity score would be 0%. Because they contain different information, sentences, paragraphs, and so on, duplicates obtained from multiple sources get scored separately. Therefore, submissions with some similarity to assignments enabled by other students are not automatically rejected as duplicates. Instead, they are added to a master list called the "Pending Review List". The list can hold up to 200 items. When Turnitin checks email, it searches the pending review list first before checking for new submissions.
Turnitin recommends that you enable only those sources that you trust completely.
A similarity percentage of 35% indicates that the students are utilizing word-for-word content from a source that is not properly referenced elsewhere in the work. This is plagiarism, and the majority of teachers will not accept the work in this format.
Turnitin reports two different types of violations: exact matches and substantial similarities. Exact matches occur when there is a perfect match between two pieces of academic work. Substantial similarities include cases where large portions of text have identical words or phrases. In these situations, the original author's ideas cannot be attributed to the student because they have been directly copied from another source. Even if students claim to have written their own work, if they have not used their own thoughts or ideas, they have plagiarized someone else's work.
The more text that is taken from another source, the higher the likelihood that your instructor will give you a low score.
Exact matches only happen when the entire piece of writing is taken from one place. With substantial similarity cases, some parts may come from one source and other parts may come from another, which means that your work has been influenced by both sources.
The Turnitin percentage that is acceptable for a similarity score In the similarity report, any Turnitin percentage less than 25% is acceptable. A Turnitin plagiarism score of 25% or less indicates that your paper is original. Scores between 26 and 50% indicate papers with minor errors that may not be considered plagiarism.
A Turnitin similarity score of 100% means that the document exact matches one of the cited documents. Although such scores are possible, they are very rare. Documents with similarity scores near 100% usually contain very similar content, such as when multiple copies of an original document exist.
Turnitin scores greater than 100% can sometimes occur if there are multiple versions of a document available online with different citation information. For example, if you reference page 12 from a document at www.turnitin.com and page 13 at www.turnitin.com, then both pages would receive a similarity score of 100%. However, only one document should appear in your results because it's hard to compare two identical pages.
If this situation applies to your case, please contact us via email at [email protected] so we can remove the duplicate document from your results.
The assignment might have been configured to either not show you the similarity report or to not create a report. Examine the assignment details or ask your instructor whether you believe you should be able to view a similarity report.
In terms of percentages, the American Psychological Association states:
The Interpretation of the Similarity Report Blue: There is no matching text. Green: Out of 24 percent of the text, there is only one matching term. Yellow: text matching of 25–49%. Orange text matches 50-74 percent of the time. Red indicates a text match at 75–100%. Finally, when all red terms are matched, it means that your paper is completely unique.
Turnitin provides two types of results: detailed analysis and quick hits. The detailed analysis report will display any sentences with suspected plagiarism, along with the source page for reference. This report can be accessed by selecting "Detailed Analysis" under the Results tab. The quick hits report will display any common words or phrases found in both your original work and the cited source. This report can be accessed by selecting "Quick Hits" under the Results tab.
If you're unsure about what content is being attributed to you, use the "See Examples" feature. This tool will take you to a page containing similar material that other students have submitted. You can then follow the instructions below the page to determine how to proceed with your assignment.
