Student representation and student partnership differ and the difference matters. To further scholarly understanding of, and appreciation for, the important difference between the two, we examine these two commonly evoked conceptions for student voice in higher education. We draw on two points of difference--responsibility and access--to illuminate conceptualisations and discourses of each in the current literature. In doing so, we clarify the unique contributions of each, shaped by differing contexts of interaction, and articulate issues arising by confounding and conflating partnership and representation in the name of student voice. Advancing an argument for an ecosystem of student participation grounded in student voice, we warn of the harm in positioning student partners as speaking for other students and the risk of diminishing the importance of elected student representation systems in favour of staff selected student partner models of student representation.
