Gradescope: Manually Adding Student Numbers to Synced Rosters for Improved Student Matching
Added on June 17, 2026 by Rim Zakaria
This article provides a downloadable PDF that explains how to manually add Student Numbers to a Gradescope roster when they are not included in the LTI roster synchronization from OWL Brightspace.
Student numbers provide a more reliable method for matching student submissions in Gradescope than the students’ UWO usernames transmitted through the OWL Brightspace LTI integration. Adding Student Numbers to the Gradescope roster can improve submission-matching accuracy, reduce the likelihood of mismatches, and simplify the process of associating scanned or uploaded submissions with the correct students.
The guide outlines the steps to manually update student rosters in Gradescope and highlights key considerations to maintain data accuracy and consistency between Gradescope and OWL Brightspace.
Important: Complete the following steps only after the final roster synchronization between your Gradescope course and OWL Brightspace course. If you synchronize the roster again after uploading Student Numbers, the Student Numbers in the Gradescope roster will be overwritten by the UWO usernames provided through the LTI integration. In that case, you will need to repeat the Student Number upload process.
