Sense: adjective/1
'Coed' (short for coeducational) is slightly informal and commonly used in North American conversational English. 'Coeducational' is the full, more formal term that appears in official policies, school catalogues, and academic writing. 'Mixed' (chiefly British) describes a school whose student body includes both genders — you might hear 'a mixed comprehensive' in the UK. 'Integrated' is broader and more historically loaded; it can refer to racial desegregation, though it does overlap with coeducational meaning in contexts like 'an integrated school system.' For contrast, 'single-sex' (or 'all-boys' / 'all-girls') names the opposite arrangement. Example: 'The university went coed in 1972' (spoken, casual) vs 'The board adopted a coeducational admissions policy' (written, official).

Etymology
'Coed' first appeared in the late 19th century as a noun meaning a female student at a coeducational institution. It is a shortening of 'coeducational,' which combines the prefix 'co-' (meaning 'together,' from Latin) with 'educational.' By the mid-20th century, the word was also used as an adjective describing schools that admitted both genders. Today, the noun use sounds somewhat dated in the United States, while the adjective remains common in informal speech.
