The Carnegie Foundation for the Advancement of Teaching is a prominent organization in the United States dedicated to improving education. Founded in 1905 by Andrew Carnegie, it focuses on research and policy initiatives that enhance teaching and learning across various educational levels. The foundation aims to promote effective practices and foster innovation in education. One of its key contributions is the development of the Carnegie Classification of Institutions of Higher Education, which categorizes colleges and universities based on their mission and programs. This classification helps researchers, policymakers, and educators understand the landscape of higher education and informs decisions related to funding and support.
