The National Center for Science Education (NCSE) is a not-for-profit membership organization in the United States whose stated mission is to educate the press and the public on the scientific and educational aspects of controversies surrounding the teaching of evolution and climate change, and to provide information and resources to schools, parents, and other citizens working to keep those topics in public school science education. Based in Oakland, California, it claims 4,500 members that include scientists, teachers, clergy, and citizens of varied religious and political affiliations. The Center opposes the teaching of religious views in science classes in America's public schools through initiatives such as Project Steve, and has been called the United States' "leading anti-creationist organization". The Center is affiliated with the American Association for the Advancement of Science.
In 1980 Stanley L. Weinberg, a veteran high-school teacher in Iowa, began to organize statewide Committees of Correspondence "committed to the defense of education in evolutionary theory," modelled upon the committees of correspondence in pre-Revolutionary America. Their purpose was to keep interested parties informed about creationist endeavours and to share ideas for responses, allowing a political response at a local level. This grew into volunteer networks in most states, with the Creation/Evolution Newsletter interconnecting them, which was incorporated as the NCSE in 1983. In 1987, author and lecturer Eugenie Scott, who holds a PhD in Physical Anthropology, became its executive director. The Board of Directors and official supporters, as explained by NCSE, "reflects our scientific roots."
