The Students Assessing Teaching and Learning (SATAL) Program at the University of California, Merced offers assessment support for faculty and program leads while engaging diverse, cross-program undergraduates in students-as- partners experiences in a work setting. Grounded in the Students as Partners (SaP) principles of respect, responsibility, and reciprocity (Cook-Sather, Bovill, & Felten, 2014), our assessment of the SATAL program reveals benefits for both students and faculty acting as co-creators of teaching and learning. Using the SATAL program as an example, we offer readers a logic model to guide the development of student-faculty-staff partnerships and assess the impact of these programs in a more meaningful and consequential manner. We also provide lessons learned from our evolving SATAL program to support others interested in designing sustainable student assisted assessment partnerships.
