This paper is a status update for an NSF-funded project aimed at developing and collecting validity evidence for an instrument to help colleges improve the impact of their student support investments. By enabling the assessment of support provided to undergraduate students in STEM (science, technology, engineering, and mathematics), such an instrument will aid STEM educators and college administrators in monitoring progress and identifying unmet needs in local environments, thereby providing data-driven evidence for targeted interventions. In this executive summary, we present: 1) an overview of the instrument development process; 2) an evaluation of the prototype for face and content validity; and 3) a revised instrument and pilot data to determine test validity and reliability across varied institutional contexts.
