Like regular Group items, depending on the settings you've chosen, everyone can see everyone else's progress and make comments.

Note that only Day-Based Courses can be assigned to a group; step-based courses by design are self-paced and thus cannot be assigned to a group.

You'll then notice that for each item you add to the course, you'll have the ability to set the Client visibility in groups. There are four different levels of transparency you can allow. 

Starting a Group Course

Starting up a Group Course is as simple as choosing a Group to be the participant in your course:

You can also start a course for the group by going to the group's Courses tab and clicking +Course Participation.

 

When choosing to put a group into a course, you can indicate exactly which members of the group will be doing it, handy in cases when one or more members will not be joining in:

Just like with individual courses, click on the magnifying glass to see an overview of how the group is doing.

Like with individuals, clicking the Edit icon allows you to pause, rewind, fast forward or altogether stop the course progression. You can also add or remove group members.

If you have enabled Course Pages for this particular course, each group member will be able to visit the Course Page to see all the course content in one place.

Group Courses are a fantastic way to put a collection of people through a standardized program, and have them benefit from the joint accountability and transparent results as the program unfolds.  Like Group assignments given out in an ad hoc fashion, the open transparency is powerfully motivating to individuals who are a part of the group.
