This case study explores the implementation of a collaborative initiative that transformed the traditional role of teaching assistants (TAs) into student-faculty partners in two psychology courses. The objective of the collaboration was to leverage the insights and contributions of undergraduate students as co-creators of instruction for students' engagement and meaningful learning experience. The case study highlights the processes, impacts, and challenges of these partnerships, revealing opportunities for student partners to develop pedagogical and assessment literacy, enhance communication and leadership skills, and gain insights into student behaviors and preferences. Pedagogical and curricular gains were observed, including the incorporation of student insights into instructional activities and improved teaching materials. However, challenges related to power dynamics and student perceptions of privilege were also identified. The findings emphasize the importance of careful navigation and the creation of meaningful opportunities for student engagement in higher education.
