The first year of college or high school is referred to as Freshman year. A freshman (slang alternatives that are usually derogatory in nature include fish, new-g, fresher, frosh, newbie, freshie, snotter, fresh-meat, skippie, etc.) is a first-year student in college, university or high school. The term 'pupil' (originally a Latin term for a minor as the ward of an adult guardian, etc.) is used in some Commonwealth primary and secondary schools (particularly in England and Wales) instead of student, but once attending higher education such as sixth-form college, etc., the term student is standard.
