Add a private course to the iTunes U catalog
By default, all courses created in iTunes U are private. To add a course to the iTunes U catalog and make it available to the public, an affiliated instructor must submit a request to their institution’s iTunes U Public Site Manager administrator and the administrator must add the course to the institution’s iTunes U site.
The affiliated instructor requesting the private course become public must be the course owner and must have an Apple ID or Managed Apple ID that was previously used to sign in to iTunes Store, App Store, iCloud, Apple Books, or Apple Online Store and the owner of the course. See Sign in with your Apple ID.
Before you submit a private course to the iTunes U catalog, use Course Settings to confirm the course is associated with a category.
