The purpose of this study was to examine patterns of language use in score reports within a North American context. Using a discourse analysis approach informed by conversation analysis, we explored how language was structured to express ideas or (re-)produce values, practices, and institutions in society. A sample of 10 reports from the United States and Canada within the domain of accountability testing was selected. Observed patterns of language represented micro-discourses embedded within broader discourse related to accountability mandates within each country. Three broad themes were identified within and across the score reports-Displays of Information, Knowledge Claims, and Doing Accountability. Within each of the broad themes were sub-themes-word choice, and visual representations, script formulations, hedging, establishing authority, and establishing responsibility-that characterized more fine-grained textual features. Future research may explore empirical evidence for the social dynamics identified through this study's textual analysis. Complementary lines of research on cognitive, affective, and socio-cultural factors of score report interpretation and use are encouraged.
