Med-Challenger gives you a Score Bar and Global Average for each assignment in the Assignment Activity section. "Global Average" refers to the average score across all Med-Challenger users for a given assignment.
In the Assignment Activity section, expand any completed/effective/in-progress assignments. The Score Bar will appear.

The Global Average is a quick way for Program Administrators to compare their learners' average score for any given assignment to the average score for all Med-Challenger users taking the same assignment.
