The American Medical College Application Service (AMCAS) is a service run by the Association of American Medical Colleges through which prospective medical students can apply to various medical schools in the United States. It thus acts as something of a Common Application among the schools. Osteopathic medical schools (granting Doctor of Osteopathic Medicine, or D.O., degrees) have a similar system called the American Association of Colleges of Osteopathic Medicine Application Service (AACOMAS).
