Since fewer than 13% of probationary and 40% of non-traditional students complete their undergraduate degree, educators should search for new strategies to retain probationary and non-traditional students (Hamman, 2018; Muljana & Luo, 2019). The mixed-methods study analyzes how traditional probationary and non-traditional students perceive academic hope, the correlation between academic hope and academic achievement, and the efficacy of an academic hope intervention. The study includes qualitative data to explore how students conceptualize academic probation and academic hope. The mixed-methods study also utilizes descriptive and inferential statistics to determine the correlation between academic hope and academic achievement. Lastly, the study determines the efficacy of an academic hope intervention for traditional probationary students. The study's results suggest probationary students feel an array of negative emotions from their placement on academic probation. The results also dismantle the assumption of how probationary students are underprepared or unmotivated. The study discovered probationary students had inflated expectations and lacked a sense of belonging to the institution, both of which seem to contribute to students' lack of academic success. Next, the study's results indicate there was not a significant correlation (r=0.127, r=0.014) between academic hope and academic achievement. The results suggest there is a practical benefit with administering an academic hope intervention. The academic hope intervention increased seven participants' level of academic hope from average to high. The results indicate a strong correlation (r=0.828) and effect size (0.543) between pre-and post-intervention academic hope scores. The study provides recommendations for how educators can support traditional probationary and non-traditional students.
