Question: Is Major GPA (distinct from UC GPA) in the current data set or planned?

This is an interesting data point. And like most things GPA related it can get messy really quickly. There's only one place in the current system where any type of major GPA is visible, and that's the degree audit. To more specifically the audit has an upper division major GPA which generally excludes all lower division classes. Except that the actual logic is based on classes used for upper division requirements, not the classes themselves, which means in rare cases when a lower division class is used for an upper division requirement, it does pull that in. So far as I know there's no other widely accepted calculation for major GPA, at least in the policy or in ISIS. As we dig in I think it's likely we'll find many subtlety different calculations related to major GPA. But it's absolutely worth having a conversation about.

Agree that there are bigger issues with calculation and questions about consistency.  What is reported via DARS is what academic units use to certify at time of graduation, giving the data operational and analytical value, even if the calculations are not consistent or not in line with policy.

Relevant policy is here:  http://senate.ucsd.edu/operating-procedures/educational-policies/grading-and-gpa-calculations/

Seems like departmental compliance, accuracy of calculation, and relevance as a data point are all separate considerations.  Would not want to see this excluded as a data point because some units are not compliant and/or because the calculation logic is inconsistent.
