stopped accrediting institutions outside of New York, DTS was accredited in 1969 by the Southern Association of Colleges and Schools and in 1994 by the Association of Theological Schools in the United States and Canada. The school is also a member of the Association of Christian Schools International (ACSI), the Evangelical Training Association (ETA), the Jerusalem University College, and the Institute of Theological Studies (ITS). Theology DTS is known as a center of modern dispensational teaching due to Dr. Chafer's development of a systematic theology which approaches the Bible with a "premillennial, dispensational interpretation of the Scriptures." Systematic Theology, his eight-volume work describing this approach, was first published in 1948 and is still a required textbook for some courses at DTS. Notable theological beliefs of the school include: premillennialism, dispensationalism, and Biblical inerrancy. The school considers itself non-denominational within Protestantism, and offers classes in all 66 books of the Protestant Bible. Notable people In a 2009 study conducted by LifeWay Research, Protestant pastors named preachers who had most influenced them.
