No. It's typically just a regular classroom that's not being used.
Saturday detention might be held in the cafeteria or auditorium.

Yes, detention rooms are quite common in American schools. They can either be certain rooms designated for that purpose or other school rooms such as the library may substitute as a detention room. It all depends on the number of students subject to after-school detention. :-))

lol, two conflicting answers :o)

Ok well, then none of the high schools in my area that I was/am familiar with had a room created for the sole purpose of detention.

@ # 3.well that must be a pretty poor school district.

After all you know the saying: Poverty is not a disgrace, but it's pretty inconvenient.

:-))

It was most definitely not a poor area, Helmi. :o)
Maybe they were just idealists and thought we wouldn't have need of a special room, hehe :o)

Thanks Guys!
Saturday detention? Wow, never seen a teacher work on Saturdays around here :)
Here in Switzerland detention is pretty uncommon, usually we had to go pick up cigarette buds out on the yard or something... :)

We had detentions in Room 19. During school hours it was just another classroom, but as of 3:45 p.m. - and on Saturday mornings! - it was the "det room".

Is a poor school one that lacks money or one of insufficient quality?

The school I teach in has two detention rooms, though we have different names for them. They are frequently full. Students spend the entire day there, so actually they are in-school suspension rooms. Many of the teachers would like Saturday detentions to be an option. Something that cuts into a student's free time is more likely to be an effective deterrent. There are after school detentions at my school, too, but I don't actually know where they are held.

The public high school where I teach uses the lyceum or cafeteria for most detentions. For Saturday school students might go to the classroom of the teacher who is supervising. (Saturday school supervision is an extra assignment, and the teachers are paid a stipend for taking on this extra duty.) In-school suspensions also use the lyceum. We don't have a separate room solely for detentions.

Like nearly every public school in California these days, we are poor in the financial sense.
