Example of Completed and Incomplete

In this example the project requirements may define the following:

The SCO can be evaluated as completed once the learner has started the animation. If the learner only accesses the introduction material and does not start the animation, then the SCO is evaluated as incomplete.

This is only an example of how Completion Status is evaluated. There are many other ways beyond this example. How Completion Status is evaluated is up to the content creator.
