The World Student Christian Federation (WSCF) is a global ecumenical federation of student Christian groups. It is the oldest international student organization, founded in 1895 by North American evangelist and global ecumenist John R. Mott. It was the first international organization committed to equal participation of men and women, and unique among interdenominational Christian organizations in holding its plenary conference outside Europe early on – Tokyo in 1907, Istanbul in 1911, Beijing in 1922, and so on. The local and national groups that make up the Federation are largely known as Student Christian Movements (SCMs). In some cases, the youth or student movement of a national church or other ecumenical organization is a member of the WSCF. While university, polytechnic and other tertiary students make up the bulk of SCM membership, high school students are also involved in some movements. Today, WSCF connects two million members in over 90 countries, having over one hundred affiliated national movements which span the six WSCF regions: Africa, Asia-Pacific, Europe, Latin America and Caribbean, Middle East and North America.
