Screen.Recording.2026-03-13.at.6.23.31.PM.mov

What this changes:

• New Certificates Page: Adds a tabbed interface for viewing issued certificates and generation history
• Issued Certificates Tab:
  • Displays all learners in the course with their certificate status
  • Supports filtering by certificate status (received, not received, audit passing/not passing, errors, granted exceptions, invalidated)
  • Includes search functionality to find learners by username
• Certificate Generation History Tab: Displays a history of certificate generation tasks with dates and details

User roles impacted:

• Course Staff/Instructors: Can now view and manage certificates for all learners in their course
• Operators: New tab is only shown when certificates are enabled for the course

Supporting information

Related to the broader instructor dashboard modernization effort in the Open edX platform.

Testing instructions

Prerequisites:

• Ensure certificates are enabled for a test course
• Have learners enrolled in various states (passed, audit, failed, with/without certificates)
• Running this branch of openedx-platform feat: Instructor Dashboard - Add Certificates and generation history v2 api openedx-platform#38176

Test Issued Certificates:

1. Navigate to Instructor Dashboard → Certificates tab
2. Verify the "Issued Certificates" tab loads and displays learners
3. Test search functionality by entering a username
4. Test filtering by selecting different certificate status filters
5. Verify pagination works correctly
6. Test certificate regeneration:
   • Select a filter (e.g., "Granted Exceptions")
   • Click "Regenerate Certificates"
   • Confirm the modal displays correct information
   • Confirm regeneration (verify success message)

Test Certificate Generation History:

1. Switch to "Certificate Generation History" tab
2. Verify past generation tasks are displayed with dates and details

Test edge cases:

• Navigate to a course with certificates disabled (should show 404)
• Test with empty results
• Test error handling

Best Practices Checklist

We're trying to move away from some deprecated patterns in this codebase. Please
check if your PR meets these recommendations before asking for a review:

• Any new files are using TypeScript (.ts, .tsx).
• Deprecated propTypes, defaultProps, and injectIntl patterns are not used in any new or modified code.
• Tests should use the helpers in src/testUtils.tsx (specifically initializeMocks)
• Use React Query to load data from REST APIs. See any apiHooks.ts in this repo for examples.
• All new i18n messages in messages.ts files have a description for translators to use.
• Imports avoid using ../. To import from parent folders, use @src, e.g. import { initializeMocks } from '@src/testUtils'; instead of from '../../../../testUtils'
