The Arthur Vining Davis Foundations supports innovative professional development programs that strengthen teachers in grades 9-12 and their teaching. Projects may cover a wide range of initiatives intended to improve teaching. For example, projects might be designed to improve professional development for in-service and pre-service teachers, strengthen teaching skills, support practical research in teacher and high school education, or encourage innovative use of technology and new techniques for presentation of classroom materials in high schools. Projects should aim to develop solutions with potential for wide application or replication by others. Requests to support well-established programs should be for initiatives with the potential to improve the program significantly. Special consideration will be given to projects in their early stages that address the concerns and problems of secondary education on a national level.
