Use the adjective coeducational to describe something that includes or allows both boys and girls. A coeducational summer camp, for example, has both male and female campers.

Schools that aren't coeducational are known as "single-sex." Many women's colleges have begun admitting men over the years, gradually becoming coeducational. The most common way to use the word is to abbreviate it as "coed" or "co-ed." The adjective coeducational has been around since the 1880's, which is around the same time that many United States colleges and universities, previously open only to men, started accepting female students.
