Turnitin SimCheck is a plagiarism prevention tool that scans student submissions to identify plagiarism or incorrectly cited text. Submissions are compared against various sources to generate a Similarity Report where matched text is highlighted along with information about the matching source. It is possible for SimCheck to be enabled on Engage forums and assignments.
This document illustrates how faculty can access SimCheck Similarity Reports, interact with the reports, and enable SimCheck within an Engage forum or assignment.
Before using SimCheck, it is important to understand SimCheck's capabilities and requirements:
SimCheck may be available for Engage assignments and forums depending on your institution's settings.
SimCheck compares student submissions against two repositories: internet sources and an institutional submission index.
The institutional repository is composed of papers previously submitted to SimCheck enabled activities on the Engage site.
The submission indexing setting must be enabled for papers to be added to your institution’s repository.
Students must accept the Turnitin End User License Agreement (EULA) before a Similarity Report will generate.
Submissions must meet certain file requirements:
100 MB file size maximum
20 word minimum
Accepted file types: MS Word, PowerPoint, Excel, PDF, OpenOffice, rich text format, plain text, and more.
A Similarity Report will become available after a file or post has been submitted and processed by SimCheck. Processing time is typically between 5-15 minutes but may be longer depending on file size and Turnitin server status.
Open the assignment and select the View all submissions button.
Locate the student’s submission you wish to review.
Click the Similarity Score percentage next to the Turnitin Icon to open the Similarity Report.
Do not click the file name - this will download the original file instead.
You can also open the Similarity Report from the Grade screen.
Open the forum and navigate to the student’s post.
At the bottom of the post, click the Similarity Score percentage next to the Turnitin Icon to open the Similarity Report.
Turnitin will also generate Similarity Reports for file attachments in forums. The Similarity Score percentage and the Turnitin Icon will appear below the file name. Click the Similarity Score percentage to access the Similarity Report.
Do not click the file attachment name - this will download the original file instead.
A high or low Similarity Score is not a definitive measure of plagiarism. The SimCheck Similarity Report and score should be used as a guide in evaluating the originality of a student's work. Always review the Similarity Report and consider the matched sources before making a judgment.
The Similarity Report displays the student’s submission on the left and a Sources Panel on the right. Matched text will be highlighted on the student’s submission. Clicking matched text will open the corresponding entry in the source panel.
The Sources Panel offers two views. Use the dropdown arrow at the top of the sources panel to switch between them.
Sources overview: displays a list of the top sources found in the document. Overlapping sources will not be displayed.
All sources: displays a list of every source found in the document. Includes overlapping sources, so the total percentage match will appear to be higher than the student’s Similarity Score.
Click a source to view details:
Number of matches from the source. Click the arrows to browse through additional matches
Link to source (internet sources only)
Excerpt of source text. The matched text is highlighted.
View Full Text Depending on policy, this may not be available for matches with other student papers.
Exclude Source button
Individual sources can be excluded by clicking the Exclude Source button in the source details.
Once you have excluded a source, a Similarity Exclusion link will show at the top of the Sources Panel. Click the link to view a list of excluded sources.
On the Excluded Sources list, click the name of a source to include it in the Similarity Report again. Click the Include All Sources link to remove all exclusions at once.
Certain exclusion categories can also be set to reduce matches that do not typically indicate plagiarism, such as bibliographies. Note: these exclusions will not show on the Excluded Sources list.
Click the gear icon at the top of the Sources Panel to open the Settings page.
There are 6 exclusion options:
Turnitin SimCheck must be enabled on an assignment or forum for Similarity Reports to generate.
From the assignment or forum, click the gear icon and select Edit Settings.
Scroll down to the Turnitin Integrity section and click to expand.
Choose your desired settings:
Enable Turnitin: This must be checked for Similarity Reports to generate
Exclude from Similarity Reports: exclude certain match categories by default
Submission Indexing: This setting must be enabled to store student papers in your institution’s submission repository. If this is not enabled, student submissions will not be stored for future comparison.
Generate Similarity Reports: Choose when reports will generate.
Immediately and regenerate on due date
Allow students to view Similarity Reports: if this is disabled, students will only be able to see their Similarity Score.
Process draft submissions: If your assignment allows draft submissions, you can enable this to generate a similarity report for students before they have officially submitted. This is generally not enabled.
Once you have selected your settings, scroll down and click Save and return to course or Save and display.
