How long is high school detention?

High school detentions can vary in length depending on several factors, such as the severity of the infraction, the school's policies, and the individual school administrator's discretion. Generally, detentions range from 30 minutes to several hours, with the most common duration being one hour. Some schools may also have different types of detentions, such as morning or evening detentions, Saturday detentions, or even longer-term detentions that may require attending multiple sessions over the course of several weeks.
