A learning platform should be judged by the teaching and student journey, not only a course homepage. Pilot Sakai with one real assignment pattern using disposable users.
Create a course, publish materials, set a due date, accept submissions, grade with feedback, allow one resubmission, and release results. Test as teacher, student, and administrator. The Sakai community documentation describes assignment and gradebook workflows; verify the release and institutional integrations you will operate.
Check accessibility, mobile access, notifications, roster sync, export of grades, and restore of course materials. If migrating, import a sample course and ask a teacher to run it without developer help. A successful decision includes the people who maintain academic records and privacy policies, not just the IT team's installation test.
