How is a SCO Mastered?

The SCO itself can determine the success status—whether the SCO was passed, failed or unknown—based on the learner's performance. There are instances where other data model elements can be used to evaluate, and potentially override, any SCO reported success status. However, this is beyond the scope of this data model element content.

What then can determine if a learner passes or fails a SCO? Is it achieving 90% on an assessment or getting 15 out of 20 questions correct? There are an infinite number of possibilities and criteria for evaluating whether a learner passes or fails a SCO. Therefore, the mastery of a SCO depends on the project requirements and design of the content. It could be based on passing a certain percentage of interactions, meeting a certain percentage of objectives, a total score for a test or comparison of a quiz against a mastery score. Mastery of a SCO doesn't always have to be determined quantitatively by comparing numerical analysis or based on scores. A SCO can be evlauated mastered by completing a set of steps or actions and not tracking a score. The criterion differs from project to project, content to content and even from SCO to SCO. The point is that criteria for mastery must be defined.
