This publication builds on the work of AAC&U's VALUE project (Valid Assessment of Learning in Undergraduate Education)—a multi-tiered effort that, in its first stages, harnessed the expertise of hundreds of faculty and other education professionals across American higher education to identify the most commonly agreed upon criteria and standards of judgment to be used in assessing student work. VALUE has since become a national movement to change the way we envision and approach the assessment of student learning gains and accomplishments in college. Assessment That Works contextualizes this movement, describes several illuminating case studies of VALUE in action, and exhorts us to maintain the momentum and raise the visibility of this effort.
