Over 10 years ago, a National Research Council committee led by Jim Pellegrino and Robert Glaser generated the fundamental text on educational assessment titled, Knowing What Students Know: The Science and Design of Educational Assessment (NRC, 2001). In this document, the authors emphasize that assessment is a process of reasoning from evidence, ‘‘a process by which educators use students’ responses to specially created or naturally occurring stimuli to draw inferences about the students’ knowledge and skills’’ (National Research Council 2001, p. 20). Knowing What Students Know (NRC, 2001; KWSK) was fundamental to advancing the conversation on assessment in science and other disciplines for several reasons. First, KWSK provided a set of guiding principles for the development and evaluation of educational assessments. The assessment triangle, introduced as an assessment model, was particularly important as it brought recognition to the importance of using cognitive models to drive the design of the assessment and define the empirical evidence needed to support the interpretations derived from observed performance. Second, KWSK called for a ‘‘balanced assessment system’’ of classroom and large-scale assessments that are: comprehensive—using multiple sources of evidence about students’ learning; coherent—a shared learning model coordinating curriculum, instruction, and assessment; and continuous—longitudinal assessment of learning progress over time. This assessment system posed a model to follow in any educational system. Third, KWSK confirmed the idea that assessment should be designed with a specific purpose in mind and cannot serve multiple purposes. Fourth, KWSK emphasized the necessity for assessments to be sensitive to cultural and linguistic difference characteristics of the tested audience. Fifth, KWSK presented new advances in educational measurement, psychometrics, and technology. In all of these ways, KWSK set a high bar for quality assessments. At the
