Night schools are institutions that offer education or training programs during the evening or at night. There are several synonyms for night schools, including evening schools, after-hours schools, night classes, twilight schools, and adult education programs. Evening school is a term used to describe any school that operates outside the regular school day. After-hours schools, on the other hand, are institutions that offer classes after the regular workday. Twilight schools, meanwhile, typically refer to schools that cater to students who are unable to attend regular classes during daylight hours. Lastly, adult education programs refer to institutions that offer education and training to adult learners, usually during evenings or weekends.
