Key Findings
High School GPA (weighted) was a strong predictor of retention HS GPA (W) was correlated with first-year GPA at FIU
Graduation rate was affected by HS, first term, and first year GPA Performance in gateway courses affected retention and graduation rates

Recommendations
Disseminate information to faculty and staff GPA requirement?
Monitor course performance Implement a “BA” track
Additional support (i.e. tutoring, learning assistants) Collaboration with Chemistry department
Behavioral assessment?
