The researchers assess the relationship of fraternity/sorority membership and semester of recruitment on grade point average (GPA) and student retention, adjusting for covariates through sub classification by propensity score. The findings suggest a consistent positive relationship between fraternity/sorority membership and retention and a varying relationship between fraternity/sorority membership and GPA. Fraternity/sorority membership has a negligible effect on GPA over time, with the exception of the recruitment and pledging semester.
