A Bible college, sometimes referred to as a Bible institute or theological institute, is an evangelical Christian or Restoration Movement Christian institution of higher education which prepares students for Christian ministry with theological education, Biblical studies and practical ministry training.
Bible colleges primarily offer undergraduate degrees, but may also offer graduate degrees, lower-level associate degrees, certificates or diplomas in specialized areas of Christian training where a full degree is not required.
Bible colleges differs from other theological institutions in their missionary perspective.  In Europe, the first schools that could be classified in this category are Theologisches Seminar St. Chrischona founded in 1840 by Christian Friedrich Spittler in Bettingen, Switzerland and the and Pastors' College (renamed Spurgeon's College) established in 1856 by Pastor Charles Spurgeon at London in United Kingdom.
In the United States and Canada, the origins of the Bible college movement are in the late 19th-century Bible institute movement. The first Bible schools in North America were founded by A. B. Simpson (Nyack College in 1882) of the Christian and Missionary Alliance, and D. L. Moody (Moody Bible Institute in 1887). Many were established as a reaction against established theological colleges and seminaries, which conservatives believed were becoming increasingly liberal and undermining traditional Christian teachings, such as Biblical inerrancy.
The American Bible college movement developed in reaction to the secularization of U.S. higher education. The "Bible institute/college movement" has been described as "a protest to the inroads of secularization in higher education and as a base for the education of lay workers and full-time Bible teachers, evangelists, and pastors". As one historian put it, "It is not a coincidence that the Bible institute movement grew up during the very period when the philosophy of naturalism became prevalent in American education". Between 1882 and 1920, 39 Bible schools were founded in the United States.
Bible colleges generally confer bachelor's degrees, most often in biblical studies and various divisions of Christian ministry, pastoral ministry and worship ministry or church music. Some Bible colleges offer degree programs in ministry-related areas that also have secular application, such as Christian education.
At some Bible colleges, associate's degrees, diplomas, or certificates are available. These programs are generally designed for laypersons (such as Sunday school teachers) who neither want nor need a bachelor's degree to perform their Christian service, but who desire additional training in such areas as Bible studies or the teachings and practices of their denomination.
Many Bible colleges in the United States and Canada that offer intercollegiate athletic programs are members of the National Christian College Athletic Association or the Association of Christian College Athletics.
The International Council for Evangelical Theological Education was founded in 1980 by the Theological Commission of the World Evangelical Alliance.  In 2015, it would have 1,000 member schools in 113 countries. 
Bible colleges are usually associated with evangelical, conservative, Christian fundamentalist denominations.[note 1] Their primary purpose is to prepare people for roles in Christian ministry. The Bible-centered curriculum is typically supplemented by structured programs of Christian service.
In the United States the average salary for a full professor at a Bible institute was around $49,000 in 2012. The student-to-faculty ratio is around 13 students to one instructor.
