The mastery target percent is inherited from the organization level into a course, but it can also be changed and overwritten for each learning path of the course. This mastery percent is primarily used for three purposes:
1) When a student completes a concept with a percentage lower than the mastery percent, they are then scaffolded down to a prerequisite concept (if one was set). The student will go through scaffolding and have a second opportunity to attempt the concept. If there is no prerequisite mapped, then the student is considered to have completed but not mastered the concept.
2) When a student completes a concept with a percentage equal to or higher than the mastery percent, then they are considered to have mastered that concept.
3) When a student completes a concept with a percentage equal to or higher than the mastery percent during an initial diagnostic, then that concept will be marked as mastered, and they will not have to complete the normal learning workflow for that concept.
Note: The mastery target percent cannot be overwritten at the course level. Once an LTI connection is established, the mastery target percent for a learning path is frozen.
