This quantitative study determined the impact of Persist Nashville's support interventions on persistence to the next semester and academic year of postsecondary education. Using Fall 2022 and Fall 2023 persistence data provided by Persist Nashville, the researchers examined the relationship between persistence and the support mechanisms of Care (emergency funding), inbound touchpoints, and pulse checks. The researchers explored these relationships for several demographic factors, including race, ACT score bands, and postsecondary school type. Persist Nashville provided data for 2,595 public school students in 2022 and 5,338 public school students in 2023. When examining persistence rates for Fall 2022 to Fall 2023, the findings suggest that students who used one of the three support mechanisms offered by Persist Nashville tended to persist at a higher rate than those who did not use the support mechanisms. In particular, the number of completed pulse checks was a predictor of student persistence from Fall 2022 to Fall 2023. Students in all demographic subgroups were slightly more likely to persist with each completed pulse check. Care was also a statistically significant predictor of persistence to Fall 2023 for several subgroups in the Fall 2022 cohort. Regarding the Fall 2023 cohort, the number of completed pulse checks was a statistically significant predictor of persistence for students at both two-year and four-year schools. The findings of this study align with both Tinto's model of student departure and Deci and Ryan's self-determination theory. Recommendations for further research into persistence outcomes for students engaged in postsecondary support programs are included.
