A Credential Summary Report in Generate Reports will give you the basic overview and percentage complete, but if you need to see specific completions you can do so through Manage Credentials.
Under Administration and Manage Credentials, open your Credential. Then, click the gear icon above Users.
Click the View Credential Summary Report icon under Actions to the right of the user’s name.
This will show you the individual’s progress, what they have done, and what is left.
