What is the difference between mastery and grading?
Mastery is the proficiency achieved by the student after going through an entire learning workflow (all the question items) of a concept. If a student's result on all question items is equal to or above the mastery percentage, then the concept is considered mastered. If it is below the mastery percentage, the concept is not considered mastered. For example, if the mastery threshold is 80%, and the student's result is 70% then they have not achieved mastery.
- Mastery calculations are applicable to each concept and executed at the end of the concept learning workflow.
- The mastery calculation for the concept is based on the Weighted Results of all items included in the concept learning workflow.
- Weighted Results take into account each item's Item Type Weight, which is determined at the organizational or course level.
Grade calculation is based on the mastery calculation of each concept. See below for how the grade is calculated in Concept Level grading and Unit Level grading:
- Concept Level grade: Grade calculation in this case will be the same as the mastery calculation, i.e., 82% mastery = 82% grade
- Unit Level grade: Grade calculation in this case will be the average of Mastery across all concepts in the unit, i.e., 82%, 80%, 76%, 74% mastery across four concepts = 78% grade for the unit.
Note: Mastery can also be determined in a concept during the Initial Diagnostic based on students' performance in a pre-defined set of questions (without going through the entire learning workflow of a concept).
