Undergraduateeducational systems, an undergraduate is a post-secondary student pursuing a Bachelor's degree. Students of higher degrees are known as postgraduates (or often simply graduates).
In the United States, most undergraduate education takes place at four-year colleges or universities. Students in their first, second, third, and fourth years of study are often called, respectively, freshmen, sophomores, juniors, and seniors (although some institutions, such as many women's colleges, substitute "first-year" for "freshman" in an attempt to remain more gender-neutral). Some institutions (liberal-arts colleges) offer primarily or exclusively undergraduate education, while most universities offer graduate study as well. Successful completion of undergraduate work generally requires the completion of many courses of varying subject and difficulty, and a concentration or "major" that focuses on a particular academic discipline.
In the United Kingdom, undergraduate refers to the first three or four years of study towards a Bachelor's degree.
