Tasks in science, technology, engineering, and mathematics (STEM) are unusually varied because they target phenomena occurring in diverse domains and call upon a wide range of abilities to perform them. The fact that STEM tasks cover such a broad spectrum of abilities makes these fields uncharacteristically inclusive: Individuals with disabilities…

Multiple uses of the same assessment may present challenges for both the design and use of an assessment. Little advice, however, has been given to assessment developers as to how to understand the phenomena of multiple assessment use and meet the challenges these present.
