Results Regarding Student Equivalence across Quarters

• Across all six quarters of the study, there was a strong relationship between the Predicted Grade and actual grade for each student.
• This data support the earlier claim by Freeman et al. (2007) that the Predicted Grade model is a robust index of student ability and preparedness across quarters and years.
• A significant heterogeneity in Predicted Grades across quarters is presented. This heterogeneity was distributed across quarters in the study: Of the 15 pairwise tests, only six were not significantly different, and these crossed levels of course structure.
