<unk>  trains students in<unk> . The entry criteria, structure, teaching methodology and nature of<unk>  programs offered at<unk>  schools vary considerably around the world. Students are trained in academic areas including scopes of practice, neurology, radiology, microbiology, psychology, ethics, biology, gross anatomy, biochemistry, spinal anatomy and more. Prospective students are also usually trained in clinical nutrition, public health, pediatrics and other health or wellness related areas. The entry criteria, structure, teaching methodology and nature of<unk>  programs offered at<unk>  schools vary considerably around the world, although in the United States programs are required to teach specific areas for accreditation purposes. A 2005 World Health Organization (WHO) guideline states regardless of the model of<unk>  utilized, prospective chiropractors without relevant prior health care<unk>  or experience must spend no less than 4200 student/teacher contact hours (or the equivalent) in four years of full‐time<unk> . This includes a minimum of 1000 hours of supervised clinical training. Students must pass boards administered by the National Board of<unk>  Examiners (NBCE) to be licensed to practice in a U.S state or territory. The boards consists of parts I, II, III, and IV, as well as other additional tests required by state or if desired by students such as the physiotherapy exam. History== In 1908,<unk>  originally began with a few months of training for<unk>  spinal manipulation. Over the next several years it grew to 18 months of training. In the 1920s the<unk>  expanded again to include subjects such as anatomy, physiology and histology. It was not until the 1950's that<unk>  schools began requiring college coursework as a prerequisite for admission. While<unk>  continued to expand its<unk> al requirements, the<unk>  still varied between institutions due to there being no single regulatory agency overseeing<unk> . This changed in 1974, with the Council for<unk>  Educate (CCE) being appointed as the official<unk>  accrediting agency. As<unk>  grew, there were two distinct groups that emerged in the profession; Straights and Mixers. The Straights emphasized a vitalistic philosophy and used spinal manipulation as their sole method of treatment. They had the belief that all disease originated from the spine. Mixers utilized spinal manipulation, but in conjunction with other therapies such as physical therapy, nutrition, electrical muscle stimulation, and more. Mixer<unk>  schools offered more medical training, which initially resulted in significant controversy. In 1997, American<unk>  schools tended to have lower entry requirements than medical or dental schools. A 2005 report stated "Early<unk>  included classes in some basic and clinical sciences along with philosophy of<unk> ."
