Hi @JacobWinters! Currently, there is not an option to use the medan score as a calculation method for the Learning Mastery Gradebook. The available calculation methods are Decaying Average, N number of Times, Highest Score, Most Recent Score, and Average. You can find additional details about each of these methods in this guide. 

You can also submit new ideas to the community to be considered for future development in the Ideas and Themes space.
