With increasing external and internal pressure to increase retention and graduation rates in select colleges along with increasing numbers of college-going populations over time, student affairs professionals have responded with a variety of programs to support students' transition to college. This study sought to examine freshman students in science majors went on academic probation at the end of their first semester. If these students did not raise their GPAs quickly, they faced academic dismissal from the institution. Consequently, the institution would not be able to retain them, and ultimately, they would not graduate. Managerial professionals at the institution created, implemented, and evaluated an intervention in the form of a success course for these students to help get them back on track, retain them, and ultimately graduate from the institution. The literatures drawn upon for this study included retention theory, probationary student behaviors and attitudes, interventions, success courses, fear appeal theories, academic capitalism, and institutional isomorphism. The study employed tests including chi-square, logistic regressions, and differences-in-differences fixed effects regressions to identify the differences and effects on performance, persistence, and graduation rates of the treatment and comparison groups. The findings of this study showed significant differences between the persistence and graduation rates of the treatment and control groups, and regression effects showed a short-term causal effect on performance as well as significant likelihoods of persisting and graduating within four or five years. Recommendations for further improvements to interventions are discussed in the final chapter.
