The College Learning Effectiveness Inventory, a new assessment tool identifying personal variables important to college student success, was constructed using empirical approaches grounded in a conceptual model. The exploratory and confirmatory studies revealed the six-underlying factors: Academic Self-Efficacy, Organization and Attention to Study, Stress and Time Press, Involvement with College Activity, Emotional Satisfaction, and Class Communication. Future research on the predictive validity would provide evidence to support use of the CLEI as a screening tool to design interventions for student academic success and retention efforts.
