To ask if non-British schools have assemblies?

Didn't have assemblies in either the US or Belgium. Also went to a British school abroad and a boarding school here and we didn't have assemblies at either.

I think very few UK secondary schools do this now, as it would need a huuuuge hall. They do year group assemblies. I have been to French and German schools (MFL teacher) and they don't seem to do this at all. And yes, teachers have smaller timetables and can come and go as they please when not teaching!

France here, no assemblies. There are no points in the week where the whole school gathers together. Our school doesn't even have a big enough room for that - the gym is strictly for sports.

Also no uniforms.

And teachers only have to be in school when they actually are teaching a class, otherwise they are free to leave.

No assemblies, no uniform.

My children have an assembly between three and six times a year. Looking back, our 20 minutes of assembly each day seems like a huge waste of time.

Yes, of course, I went to school in the US and have worked in various capacities with schools in South Africa and India (the latter two obviously follow a British educational approach though).

But yes, growing up, we definitely had assemblies. I don’t remember if it was a set weekly thing in primary, but definitely regularly enough. In secondary, we had one every day! Plus chapel on Wednesday and a second afternoon assembly with a guest speaker every Friday.

My dc’s secondary school have them once a week, but I don’t think it’s the whole school at once because there’s 1600 of them and no way they could all fit in the main auditorium at once! My primary age one does have an assembly on a Friday but it’s more for awards and I’m not sure it’s the whole school because they don’t have a hall or any central space, so not sure where they fit. I think the head teacher sort of makes the rounds and they cram 2 classes in one or something.

Based on my knowledge of American teen books, TV and films most Middle/High schools seem to have something called an "Auditorium" where assembly type things take place (or in large schools they have a speaker in the classroom and the principal talks over the PA while they are sat in "homeroom" rather than moving to the auditorium).
That's pretty much the same as the assemblies we had at my English secondary.

I don't think most UK secondary schools have whole school assemblies now.
More whole year assemblies.

Most secondary schools in the UK are so full they can no longer fit everyone into the hall at once these days. Usually just a key stage or year group.

I’d never seen such a thing - grew up in the states.

Not very often in Denmark, although occasionally the whole school will meet for something. Certainly not daily or weekly though, and no singing of hymns! There is usually “samling” (gathering) daily but that is just with your class or the other classes in the same year.
