SafeAssign is a plagiarism prevention tool that detects unoriginal content in students' papers by identifying areas of overlap between submitted assignments and existing works. SafeAssign can also be used to help students identify how to properly attribute sources rather than paraphrase without giving credit to the original source. The SafeAssign feature is effective as both a deterrent and an educational tool.
Note: Delays in SafeAssign occur throughout the semester based on high demand. Please DO NOT have students resubmit papers as this pushes them to the back of the queue. Blackboard currently reports as much as 24-36 hours or more may elapse before report results are returned.
How SafeAssign Works
The SafeAssign feature is based on a unique text matching algorithm capable of detecting both exact and inexact matches between a submitted paper and a particular source material. Assignments submitted to the SafeAssign database are compared with several different databases, including the following:
- Internet: Comprehensive index of documents available for public access on the Internet
- ProQuest ABI/Inform database: More than 1,100 publication titles and about 2.6 million articles from 1990's to present time, updated weekly (exclusive access)
- Institutional document archives: Contains all papers submitted to SafeAssign by users in their respective institutions
- Global Reference Database: Contains papers that were volunteered by students from Blackboard client institutions to help prevent cross-institutional plagiarism
Assignments accept every possible file type as an attachment to a submission. SafeAssign will only process and create Originality Reports for attachments with compatible file types. SafeAssign is only able to support file types that are convertible to plain text including the following file types: .docx; .doc; .pdf; .txt; .odt; .rtf; .html; .htm; and .zip (processing files that match any of these file types within the .zip). However, Learn Assignment's Inline Grading feature only supports the following subset of file types: .pptx; .ppt; .xlsx; .xls; .docx; .doc; and .pdf. SafeAssign will only process and create Originality Reports for attachments that match the above file types. For unsupported file types, the SafeAssign Originality Report will omit a matching score. This information is visible in the right-hand navigation bar of the new Originality Report.
These two lists of compatible file types mean that there are only certain file types that can be displayed in the Inline Grading workflow and processed by SafeAssign. Below is a Venn diagram outlining which file types support both features:
Enabling SafeAssign in Original Course View
Enable the SafeAssign tool during Assignment creation and editing, under the Submission Details section.
Faculty have the option to Exclude Submissions when creating an Assignment. This option will allow faculty to create Assignments that do not include any student submissions in the Institutional or Global Reference Databases, enabling students to "check their work" against SafeAssign sources prior to submitting a final version without subsequently revised drafts being flagged as matching the previous "draft" submissions. Like other options on Assignments, this option will be point-in-time and editable after assignment creation. If the option were changed at a later date, new submissions would honor the new state of the setting.
Enabling SafeAssign in Ultra Course View
Enable SafeAssign in the settings panel while creating an Assignment or a Test.
- Open Assignment Settings or Test Settings in a new or existing assessment.
- Under SafeAssign, select Enable Originality Report.
- Select Check submissions for plagiarism with SafeAssign.
- When you enable SafeAssign for the assessment, you can also allow students to view the Originality Report. If you allow multiple attempts, an Originality Report is generated for each attempt a student submits.
- Choose whether to exclude submissions from the institutional and Global Reference Databases.
- Close the layer. Your changes are saved!
You can enable the SafeAssign Originality Report at any time, even after students have started their submissions, but submissions are only checked when SafeAssign is enabled. Submissions received before you enable the setting aren't checked with SafeAssign.
SafeAssign Doesn't Generate a Report when Filename Has Special Characters
Please note that assignment submissions with special characters (i.e., #,:,*,space, etc.) are not evaluated by SafeAssign and will not generate a report.
It is recommended that users only include numbers, letters, hyphens, and underscores in their filenames. In cases where student users have already made a submission, change the assignment setting to allow multiple submissions and then ask them to resubmit the document after making the appropriate filename change.
SafeAssign Originality Reports
After a paper has been processed, an Originality Report will be available that will show the percentage of text in the submitted paper that matches existing sources. It also shows the suspected sources of each section of the submitted paper that returns a match. The faculty can then delete matching sources from the report and process it again. This procedure is useful to ascertain if the paper is a continuation of a previously submitted work by the same student.
Because the SafeAssign feature identifies all matching blocks of text, it is important that the faculty reads the report carefully and determines whether or not the block of text in question is properly attributed.

Interpreting SafeAssign Scores
The sentence matching scores represent the percentage probability that two phrases have the same meaning. This number can also be interpreted as the reciprocal to the probability that these two phrases are similar by chance. For example, a score of 90 percent means that there is a 90 percent probability that these two phrases are the same and a 10 percent probability that they are similar by chance and not because the submitted paper includes content from the existing source (whether or not it is appropriately attributed).
The overall score is an indicator of what percentage of the submitted paper matches existing sources. Please note that this score is a warning indicator only and it is the faculty’s responsibility to review the papers carefully to see if the matches are properly attributed.
- Scores below 15 percent: These papers typically include some quotes and few common phrases or blocks of text that match other documents. These papers typically do not require further analysis, as there is no evidence of the possibility of plagiarism in these papers.
- Scores between 15 percent and 40 percent: These papers include extensive quoted or paraphrased material or they may include plagiarism. These papers should be reviewed to determine if the matching content is properly attributed.
- Scores over 40 percent: There is a very high probability that text in this paper was copied from other sources. These papers include quoted or paraphrased text in excess and should be reviewed for plagiarism.
