We write about a cultural rhetorics approach to writing center assessment at two different institutions where we think about assessment as everyday practice that enables us to tell multiple stories about our centers. We share how we create assessment committees within the center and collaboratively develop and revise assessment approaches and instruments, particularly with consultant input. Then, we discuss the various communities that inform and benefit from our assessments, including consultants, a broad range of writing center stakeholders, and writing center administrators. Assessment as everyday practice means that we are better informed and prepared when these constituents ask questions, make requests, or operate from (false) assumptions. We hope this view of assessment leads readers to build relationships with the individuals in their centers and universities in order to create assessments that matter in particular times and spaces as well as assessments that morph and change as the readers’ cultural communities change.
