  skos:definition "Developed in 1906, the Carnegie Unit measures the time a student has studied a subject in the U.S. secondary and postsecondary education system. It was originally conceived to translate high school work into equivalencies for the purpose of college admission: Students earn one unit of high school credit upon completing 120 hours in one subject, accumulated in four or five meetings a week for 40 to 60 minutes for 36 to 40 weeks each year.
