Background: Participation in high-impact practices (HIPs) is related to student success and development. Less is known about whether HIPs can increase students’ chances of getting into graduate school in psychology. High-impact practice participation might be one strategy for students to stand out in the competitive graduate school admission process. Objective: We examined (a) the perceived availability of HIPs and (b) the perceived role that HIP participation plays in psychology graduate program admission success. Method: A total of 81 U.S. psychology professors who are involved in graduate program admission decisions rated the availability, importance, and influence of HIPs and non-HIPs (e.g., GPA) on psychology graduate program admission success. Results: Many HIPs are widely available. Of all HIPs, only undergraduate research was rated as very important and strongly increases admission chances. Participation in honors, writing-intensive courses, and applied experiences slightly increased admission chances. Conclusion: Research continues to be the most beneficial HIP when applying to graduate programs in psychology. Non-HIPs (e.g., grades, letters of recommendation) are more important in graduate program admission than most HIPs. Teaching Implications: Students, academic advisors, and faculty mentors can use the results of this study to align students’ HIP participation with postgraduation goals.
