The National Society (Church of England and Church in Wales) for the Promotion of Education, often just referred to as the National Society, and since 2016 also as The Church of England Education Office (CEEO) is significant in the history of education in England and Wales. It promotes church schools and Christian education in line with the established church. Historically it was in strong competition with the nonconformist organization British and Foreign School Society. Both promoted the monitorial system, whereby a few paid teachers worked with senior students who in turn taught the junior students. The National Society was strongly supported by the Anglican clergy, Oxford and Cambridge universities, and the established church. The nonconformist Protestants were in strong opposition.
