Differences between American and British English: school
In the U.S. and the U.K., school can mean a place where children are taught between the ages of about five and 18. But American speakers also use this word to refer to a college or a university. British institutions that provide education at higher levels are called colleges or universities. In the U.S., you say that children are in school: The kids will be in school until 3:00 today. In the U.K., they are at school. In the U.S., in school can also mean studying at a school or college instead of having a job: ♦ She’s still in school, but she’s graduating in the spring.
