If you are a student wondering how accurate SafeAssign is in detecting plagiarism on your paper, then you are not alone. Your concern is valid as very few people know how to correctly read and interpret Blackboard’s Safeassign scores in its scan results.
In this post, we dwell on these two issues in depth. But first, let us learn what SafeAssign really is and how to use it well.
SafeAssign is a plagiarism detection software and system developed by Blackboard as a solution to help educators detect cheating and copy-pasting by students. It prevents plagiarism by detecting duplicated, similar or unoriginal content in student papers.
More importantly, Blackboard’s SafeAssign also incorporates features that help teach students about plagiarism and the importance of citing borrowed work.

SafeAssign is between 92% and 97% accurate in detecting plagiarism, making it effective enough to detect copying. We tested it with 3 papers and their similarity reports had an accuracy level of between 92% and 97% compared to our actual pre-determined plagiarism percentage. Therefore, if you read and interpret SafeAssign scores well, its originality report is effective enough to show your plagiarism levels.
To test for its accuracy, we uploaded three papers.
All these three papers we used were written by our office writer and were 100% original.
This is how each of the papers describes;
The first one was an essay A, the second was a research paper, B, and the third one was a case study report, C. All these were written specifically for the test.
To test the accuracy of SafeAssign, we copy-pasted content from the internet at the following pre-determined percentages.
|The File||Number of Words||Plagiarized Content||Actual Pre-determined Plagiarism Score|
|A (An Essay)||1000 words||250 words||25%|
|B (A Paper)||2000 words||800 words||40%|
|C (Report)||1500 words||300 words||20%|
Armed with our facts, our papers, and our pre-determined plagiarism score, we uploaded the three files on Blackboard’s normal student account. We submitted at different times of the day and different days of the week when the SafeAssign systems were at different usage levels.
And the results were astoundingly impressive as the system gave us similarity scores for each file that was as close as possible to the actual rates. The following table summarizes the results;
|The File||Actual Pre-determined Plagiarism Score||SafeAssign’s Similarity Score %||Variation||% Accuracy|
From the table, it is clear that SafeAssign accuracy for the three files was between 92% and 97%, which explains the possible level of detection of plagiarism in a file.
For the essay, SafeAssign was 94.8% accurate, meaning that it detected 94.8% of the total present plagiarism. It did this by detecting that 23.70% of the essay was plagiarized, but the actual was 25% because we pasted it that way to test.
This means that SafeAssign detected that 237 out of 1000 words were copy-pasted, but the actual was 200 words out of the total 1000 words, representing 25% of the paper.
To me, this is fairly accurate for plagiarism detection software, and it shows that SafeAssign is accurate enough.
SafeAssign works by scanning all work submitted against four databases which include; a global database, a campus database, an information database, and an all content found online database.
SafeAssign uses a proprietary algorithm to detect matches to help avoid false positives for common phrases and assuring the quality of results.
The software provides links that one can use to compare cases of plagiarism found in a submitted paper. These links include;
SafeAssign provides an originality report which contains detailed information about matches found in the work submitted and the existing sources. The originality report lists the potential sources in different colors, each color representing a different source.
The campus database is usually accumulated with students’ work making it easy to detect plagiarism from the wide range of work available.
SafeAssign also helps instructors view work that has been flagged and also remove a flag that is viewed as insubstantial.
Ideally, SafeAssign cannot be wrong because it just gives a similarity score for your instructor to interpret. The similarity report is based on the detected similar content between the uploaded file and both its database and the online content. Therefore, Blackboard’s SafeAssign similarity report cannot be wrong because it needs to be interpreted to determine if a file is plagiarised or not.
At the same time, SafeAssign does not guarantee 100% accuracy. The SafeAssign program does not scan the content of papers that are from outside the public domain books and scholarly journals.
Safe assign cannot check anything from any source that has not been submitted using SafeAssign previously. This makes it not able to detect any cases of plagiarism in such texts.
SafeAssign cannot check against sources behind proprietary authentication mechanisms. These are sources that are not available publically. This makes the detection of matching results difficult.
The use of a proprietary algorithm to weigh potential matches in SafeAssign can mean that instructors may consider matches below SafeAssign confidence threshold that can be perceived by the instructor as a false negative.
SafeAssign finds the best matches from any source that is online or its database, and not just any specific source.
SafeAssign can fail to check matches from an instructor’s expected source and therefore can return a different report from what the instructor is expecting.
NOTE: The fact that SafeAssign cannot be wrong should not be confused with having a false positive. To get the difference, we hereby explain the issue of false-positive below;
Yes, SafeAssign can sometimes give a false positive but should not be a cause for alarm if you did not plagiarize. The system can return false positives because it hardly differentiates cited and uncited work. False positives include not flagging plagiarised work and flagging work that is quality and appropriate as plagiarised.
Yes. Just like any other program or algorithm, SafeAssign is prone to giving false positives and false negatives. What this means is that SafeAssign can indicate that your paper has plagiarism while in actuality it does not have.
This is what is referred to as a false positive. It also means that SafeAssign can indicate the absence of plagiarism while in reality there is. This is called a false negative.
Blackboard updates and tips reveal that false negatives and positives are a result of the inherent limitation SafeAssign has to public data for comparison.
What this means is that SafeAssign cannot check works that have not been previously submitted through it. Also, it cannot check primary sources that have not yet been released to the public.
A SafeAssign score is a score that represents the probability that the submitted paper contains matches existing in other sources. Let us first understand what a SafeAssign score is.
A SafeAssign score is a mark that indicates the probability of a paper that was submitted by a writer containing texts that match existing sources in the SafeAssign database.
This score is only a warning indicator and does not mean that a writer has plagiarized. This is because SafeAssign may list well-cited and paraphrased work as plagiarised work.
Therefore, this makes it very crucial for instructors and concerned writers to review papers submitted to determine whether the matches are properly attributed.
Reviewing the papers helps come up with a more appropriate decision on plagiarism. In fact, reviewing a paper makes you able to use other SafeAssign alternatives to check for plagiarism before submitting your paper to it.
A SafeAssign Originality Report is a report that is produced when a student submits a paper, it is processed by SafeAssign to show the level of original content and plagiarized one.
The report is provided to both the student and the instructor.
This report details the paper’s percentage of plagiarism in terms of the text within the paper that matches the sources from the database and those from the paper.
Since SafeAssign shows all text blocks that match, it is imperative for both students and instructors to carefully go through the report to determine if the block of text has been credited correctly.
To understand what is a good safeassign score, one needs to know how to read a SafeAssign score and interpret it well.
You will have to know which score is good, which is bad, and which is acceptable.
The originality report provides the percentage of the content in your paper that matches other works.
In order to know this, you need to understand the three threshold levels of the plagiarism scanner. Blackboard’s SafeAssign scores can be low, medium, or high.
These are scores below 15 percent. These are papers that contain some quotes and very few common phrases or texts that can be identified in other documents.
Scores below 15%: Such scores indicate that your paper contains a few common phrases, some quotes, or some texts that match other works. Papers with such scores do not require further analysis.
Scores between 15% and 40%: Such scores indicate that your paper contains extensive material that has been paraphrased or quoted. This may indicate plagiarism.
This is depending on the similarities detected. Let’s explore each of them.
These are scores between 15 percent and 40 percent. Plagiarism is present in these texts because they contain much-quoted material and extensive paraphrased material.
While this level may be acceptable by some universities, it requires further interpretation by the instructors.
Papers with scores between 15 and 40% show that they have significant matching content that could either be copied work or necessary external content.
Therefore, such content attracts the attention of your school or the professor. This is because these papers need to be reviewed to check and determine if the matching text is referenced properly.
Scores above 40%: In such papers, there is an extremely high probability that the material has been copied from other works. There is extreme usage of paraphrased or quoted text.
These are scores that are over 40%. These represent a high probability that the paper you submitted work copied from a source in the SafeAssign database or available online.
The Unacceptable SafeAssign Plagiarism is the one that lies beyond 40%. It is not acceptable because it shows that a paper contains extensive and excessively content from the matching content. This is the content that you either paraphrased quote. These kinds of papers need to be reviewed for plagiarism.
You can access the processed SafeAsign report on the grade assessment page. You can access this page from the Grade Center:
A good SafeAssign percentage is the one that is below 15. This means that there are few cases of matching text in your submitted work. Such a score is regarded as a good similarity score because it lies within the low plagiarism levels of 0 and 15, showing your work is original.
At this level, the original content of your writing is above 75% of your paper, which indicates a huge chunk of your work.
The remaining percentage is attributed to sources and references that are necessary for giving evidence to back your arguments.
SafeAssign considers well quoted and paraphrased work as matching text and it is, therefore, the responsibility of the writers and the instructors to review the work to solve such cases.
A bad Safe assign score is any similarity score of 40 percent and above. This level is regarded as bad because it indicates that the submitted work has a greater percentage of it copied from online sources of already in SafeAssign’s database. It also shows that your original work is low and cannot be explained by references.
The worst similarity level beyond 40% is the one that matches with files or content already in the database.
That level shows a high probability that you copied a lot of content from somewhere, either online or past papers. You can read our guide on how to outsmart SafeAssign and learn ways to avoid such high plagiarism levels.
This work includes too much directly quoted text and excess paraphrased work. Therefore, the instructors for the course should review the paper and the report to check for plagiarism.
Ideally, there is no single globally acceptable SafeAssign percentage because each university has its own plagiarism policies. However, the widely accepted score is 15% and below. The percentage varies from an institution to another, and there is no universally specified level.
The score range is widely accepted because papers with such plagiarism levels do not require any further analysis because there is no presence of plagiarism.
It should also be noted that the accepted SafeAssign score is the one that lies within the Low plagiarism level according to the university’s plagiarism policies.
Every scanned paper has a score for its report. This brings two questions to mind; What does a SafeAssign score of 100 mean? What does that of 0 mean?
A score of 0% is an indicator that the content of your paper is your own, while 100% means that the paper is extremely plagiarized.
SafeAssign percentage presents the extent of similarity probability between the texts on the database and texts on the submitted work.
This means that they have the same meaning. For example, a score of 70 percent means that there is a 70 percent probability of similarity between the submitted and the work on the SafeAssign database.
This also means that there is a 30 percent probability that the submitted and the database work is similar by chance. This is because the existing source content is in the submitted paper, whether appropriately attributed or not.
A 100 percent match in a text or passage means that the text matches a source on the database 100 percent. There is a high probability that the writer copied and pasted the work directly.
There is no problem when the well-cited statements match is 100 percent. Titles also may have a 100 percent match because other contents on the database may have the same title. This is also not a problem.
Base on our tests on the papers we uploaded and the information from the site’s website, we can conclude that SafeAssign is an accurate plagiarism scanner.
The software produces a good and reliable originality report that shows the score based on the similarity of the uploaded work with the files in its database and online sources.
To effectively understand the report, you have to know how to read and interpret the SafeAssign scores so as to know what level of plagiarism the report shows. This way, you will get the best out of the scanner by Blackboard.
This makes SafeAssign an effective tool to detect and prevent plagiarism in educational institutions, especially colleges and universities or any other institution of higher learning.
