Bridget Hamre, Ph.D. is co-founder and Chief Executive Officer at Teachstone. Dr. Hamre specializes in student-teacher relationships and classroom processes that promote positive academic and social development in young children. She has authored more than 65 peer-reviewed manuscripts on these topics in the past 15 years. Her research documents the ways in which educator-child relationships and teachers' social and instructional interactions support children's development and learning and may help close the opportunity gap for students at risk of school failure. Dr. Hamre is a co-author of the Classroom Assessment Scoring System (CLASS®) and, in partnership with Dr. Robert Pianta, led early work to scale the use of CLASS as an assessment and professional development tool across the country. She collaborates with the Office of Head Start on their implementation of the CLASS as a part of the federal monitoring process and consults with numerous states on their Quality Rating and Improvement Systems. In all of this work, her goals have been to ensure the CLASS is used in ways that accurately assess children’s experiences in classrooms and that provide teachers with the feedback and support they need to best support the children in their classrooms. Dr. Hamre received her bachelor’s degree from the University of California, Berkeley, and her master's degree and doctorate in clinical and school psychology from the University of Virginia.
