An associate degree is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study intended to usually last two years. It is considered to be a greater level of education than a high school diploma or GED. The first associate degrees were awarded in the U.K. in 1873 before spreading to the U.S. in 1898. They have since been introduced in a small number of other countries.
