The aim of this article was twofold: first, to introduce a design for a writing test intended for application in large-scale assessments of writing, and second, to experimentally examine the effects of employing a device for activating prior knowledge of topic and genre as a means of controlling construct-irrelevant variance and enhancing validity. An authentic, situated writing task was devised, offering students a communicative purpose and a defined audience. Two devices were utilized for the cognitive activation of topic and genre knowledge: an infographic and a genre model. The participants in this study were 162 fifth-grade students from Santiago de Chile, with 78 students assigned to the experimental condition (with activation device) and 84 students assigned to the control condition (without activation device). The results demonstrate that the odds of presenting good writing ability are higher for students who were part of the experimental group, even when controlling for text transcription ability, considered a predictor of writing. These findings hold implications for the development of large-scale tests of writing guided by principles of educational and social justice. •Genre and topic knowledge are forms of prior knowledge relevant to writing.•Higher odds for better writing in students exposed to prior knowledge activation.•Results support use of prior knowledge activation in standardized assessment.
