Cathy Carroll, Senior Research Associate and Project Director in WestEd's Mathematics, Science, & Technology Program, is engaged in several mathematics education projects.

Carroll is Co-Principal Investigator for the National Science Foundation-funded Researching Mathematics Leader Learning project, conducting research on how leaders develop and enhance their skills as mathematics professional developers to support teachers in deepening their mathematics knowledge for teaching.

She coauthored Learning to Lead Mathematics Professional Development (LLMPD), a video-based case curriculum designed to develop leaders’ facilitation skills, content knowledge, and pedagogy, enabling them to design and implement effective, high quality mathematics professional development, and coordinates leadership development services related to the LLMPD materials. She also coauthored WestEd's Making Mathematics Accessible to English Learners: A Guidebook for Teachers (2009) and coordinates related workshop opportunities.

Carroll served as the mathematics content specialist for Teachers as Learners: A Multimedia Kit for Professional Development in Science and Mathematics, a collaborative project of WestEd, WGBH, and the Boston Museum of Science. She also served recently on design teams for the Arizona Middle School Mathematics & Science Initiative and the Curriculum Topic Facilitation Project, as well as the Advisory Board for the Mathematics for All Project, a collaboration of Bank Street College and the Education Development Center.

Previously, Carroll was Director of the Mathematics Renaissance Leadership Alliance, a mathematics leadership initiative funded by the California Department of Education to work with district-based leadership cadres in developing teacher leadership and administrative support for quality mathematics programs. Earlier she served as Associate Director for Mathematics Renaissance K-12 and, prior to that, as Regional Director for the Middle Grades Mathematics Renaissance, a component of California's State Systemic Initiative. Carroll also has nearly 20 years experience as a middle school mathematics teacher.

Carroll is recognized nationally for her expertise in mathematics leadership and professional development, consulting with districts and projects across the country to design and facilitate leadership seminars. She received the 2008 Susan Loucks-Horsley Professional Development award from the National Staff Development Council.

Her professional memberships include the California Mathematics Council (CMC), Association of Mathematics Teacher Educators (AMTE), National Council of Teachers of Mathematics (NCTM), National Council of Supervisors of Mathematics (NCSM), American Educational Research Association (AERA), and National Staff Development Council. She is a regular presenter at conferences of these organizations. She is past president of CMC’s Northern Section and has served on program committees for CMC and NCTM. She is currently conference coordinator for NCSM’s annual conference.
