Can students view their Unicheck Reports?

Yes, if this option is enabled in assignment settings.

Navigate to the required Canvas assignment, click Settings and enable the Show or hide similarity results from students option. Students will have access to similarity reports in view-only mode.

Please see this section for more details on how to configure Unicheck assignment settings in Canvas.

Alternatively, you can download an offline version of the Unicheck Report to your device and share it as a PDF file. To do so, open the online report, go to Options and click Download PDF Report.
