In 1959, the United Student Christian Council, the Student Volunteer Movement, and the Interseminary Committee merged to form the National Student Christian Federation. The Student Volunteer Movement became the Commission on World Mission of the NSCF. Its tasks remained those of promoting missionary education, fellowship, and enlistment. It continued to plan and sponsor missions conferences, including the 19th Ecumenical Student Conference on the Christian World Mission held at Athens, Ohio in 1964 with 3000 students present. The National Student Christian Federation was reconstituted as the University Christian Movement in 1966. At this time, as the Concise Dictionary of the Christian World Mission phrases it, "the Commission on World Mission was among the first to act on the formation of a movement fully representative of the churches, and agreed that the sense of mission was sufficiently embodied in the student movement for the Commission to cease a separate existence."
