Use visibility settings and release conditions to define when students can view and access course content.
With release conditions, you can set a combination of these rules:
- Which course members or groups have access.
- When the course content is accessible, visible, and hidden.
- What student performance is required, such as submitting an assignment or scoring above a threshold on a test.
