 However, because of the gradual lengthening of post-graduate medical education, and the decline of its use as the terminal stage in training, most new physicians complete the internship requirement as their first year of residency.Notwithstanding the trend toward internships integrated into categorical residencies, the one-year "traditional rotating internship" (sometimes called a "transitional year") continues to exist.Some residency training programs, such as in neurology and ophthalmology, do not include an internship year and begin after completion of an internship or transitional year.
