Night school
school that holds classes from the late afternoon, usually for adults who work in the daytime
Night school is a special form of school. It targets adults, who usually work during the day. For this reason, the classes are held in the evening, and sometimes during the night. The focus of the kinds of education these schools is to either get a certification to study at university level, or to get further qualifications for the work people are currently doing. As the classes are held in the evening, these schools are sometimes called evening school as well.
