Monitoring and subsequently simulating student transfer patterns from one academic major (or level) to another typically enables an institution to estimate future student enrollment distributions across academic areas. At the University of Missouri-Columbia (UMC), a student flow model not only simulates the patterns of student transfer but also enables academic units to monitor the "caliber" of students transferring across disciplines as well as those exiting the institution entirely. The model has been used at UMC to: (1) provide individual feedback reports to each academic dean illustrating the number and caliber (ability) of students which that academic unit "exchanges" with other academic units including the numbers of eventual distinguished graduates and dropouts "imported from" or "exported to" other academic units; (2) analyze the attrition rate, reentry rate, and caliber of students withdrawing from UMC semester by semester; (3) calculate the contribution of each academic unit to the aggregate campus attrition rate and simulate the expected attrition rate under alternative enrollment distributions of students across academic disciplines; (4) simulate the expected enrollment and academic transfer patterns by sex as compared with actual data in order to evaluate underrepresentation of females across academic disciplines (Title IX); and (5) provide data for student counseling regarding the average frequency of student transfer, the typical semester when the first change occurs, what type of student changes academic areas most often, and "transfer profiles" for eventual distinguished graduates vs. dropouts.
