Abstract In this essay, we recount Robert Mislevy's influence on the three of us and several others in the context of the National Research Council's Committee on the Foundations of Assessment , which produced the report Knowing What Student's Know: The Science and Design of Education Assessment (aka KWSK ; NRC). We start by providing a context for the Committee's work, describe critical elements of the KWSK report, including their impact on the field of educational assessment over the last 25 years, and emphasize ways in which Bob influenced their articulation and impact.
