Correlation analysis of 18 desirable outcomes versus 8 personality-based heterogeneity variables reveals that heterogeneity associates with advantages as well as disadvantages. Ways in which group composition might be customized to benefit students with particular needs or to emphasize particular goals are described, along with their potential downsides.
