BFSS meaning in Regional ?

The British and Foreign School Society (BFSS) offers charitable aid to educational projects in the UK and around the world by funding schools, other charities and educational bodies. It was significant in the history of education in England, supporting free British Schools and teacher training in the 19th century; it continued in the latter role until the 1970s. In the 19th century it fiercely competed with the National Society for Promoting Religious Education, which had the support of the established Church of England, the local parishes, and Oxford and Cambridge universities. Both institutions promoted the monitorial system, whereby few paid teachers supervise the senior students who in turn taught the younger students.
