Writing program administrators and other composition specialists need to know the history of writing assessment in order to create a rich and responsible culture of it today. In its first fifty years, the field of writing assessment followed educational measurement in general by focusing on issues of reliability, whereas in its next fifty years, it turned its attention to validity. Overall, the field has exhibited a tension between reliability and validity, with the latter increasingly being conceptualized as involving a whole set of considerations that need to be theorized.

As writing-program administrators and faculty are being called upon more frequently to help design and facilitate large-scale assessments, it becomes increasingly important for us to see assessment as integral to our work as academics. This article provides a framework, based on current historical, theoretical, and rhetorical knowledge, to help writing specialists understand how to embrace assessment as a powerful mechanism for improved teaching and learning at their institutions.
