Katherine Furgol Castellano is a senior research scientist in the Foundational Psychometrics & Statistical Research group in the Research & Development division at ETS. She received a Ph.D. in educational measurement and statistics in 2011 and a M.S. in statistics in 2008 from the University of Iowa. She received the 2016 Jason Millman Promising Measurement Scholar award for her work on student growth scores. She continues to research student growth models, including assessing the impact of measurement error on growth scores at the student and aggregate (e.g., teacher, school, district) levels as well as investigating approaches for improving the accuracy and year-to-year stability of aggregate growth measures. In addition, Castellano has served as a methodologist on several projects, including a National Science Foundation–funded grant on assessing content knowledge for teaching (Award No. 1813254) and an Organisation for Economic Co-operation and Development–sponsored international video study project on teaching practices and quality. 

Previously, Castellano was an Institute for Education Sciences postdoctoral fellow at the University of California, Berkeley (2012–13). She has also consulted for the Council of Chief State School Officers on A Practitioner’s Guide to Growth Models (2013) and the National Opinion Research Center on the Final Report on the Evaluation of the Growth Model Pilot Project (2011).
