The Competencies interface has two different views:
The advanced view contains a navigation pane that enables you to view competency structures, as well as independent learning objectives and activity assessments that are currently not associated with a competency.
You can choose which elements are visible to course participants. For example, you might set Competencies to only display activities to users if you just want to provide a list of activities for them to view without seeing the learning objectives and competencies they might be associated with.
Note Learning objectives are only visible if they are attached to a competency that course participants can see. You must attach learning objectives to competencies with the Make competency and its children visible to users check box selected.
You can allow users to add competencies to their ePortfolio as artifacts.
