Brent Duckor, an associate professor in the Department of Teacher Education at San José State University in California, teaches courses and workshops that provide historical, analytical, and empirical lens to help students better understand the role of assessment, testing, and evaluation in education.

He also serves as a researcher, studying teacher learning progressions in formative assessment. His research on teachers' understanding and use of formative assessment in the K–12 classroom and validation of teacher licensure exams in state, national, and international contexts seeks to integrate a developmental perspective on teachers' growth in the profession. The core focus of Duckor's research on teachers utilizes mixed methods to investigate trajectories of high leverage assessment practices and examining how to model progress variables using Item Response Theory (IRT).

Prior to San José State University, Duckor taught government, economics, and history at Central Park East Secondary School in New York City in the 1990s before returning to the University of California, Berkeley, to study education measurement, testing, and assessment with the passage of No Child Left Behind.
