Student success has multiple meanings; however, the quantitative bias prevalent in the northwest American and Western Canadian postsecondary education sector restricts how student success is defined and measured. Standardised measures of student success assume that the student experience is homogeneous and risk the implementation of policies and programmes based on insufficient information. Findings from several small student focus groups suggest that unless new evaluation approaches are adopted, it is unlikely postsecondary institutions will generate the knowledge and wisdom needed to serve the goals of a diverse array of students. This article presents findings from three small student focus groups (n = 14), in an attempt to understand how students themselves define student success and how it should be measured. The results contributed to the development of five principles for culturally responsive postsecondary performance measurement that include participatory, emergent and appreciative processes and qualitative evaluation methodologies.
