3 hours per week-night and 5 hours per day at the weekend?

Mine are at a grammar school and don't do, nor are they expected to do anything near that amount.

Maybe an hour a night (usually done sometime between 5 and 7) and a couple of hours for project type work at the weekend.

DS is in yr 9 & does around 8 or 9 hours homework across the week. The idea that it could go up to 25 hours next year is the stuff of nightmares.

Not usual. My son barely does an hour per day and only a couple of hours per day at weekend and he's in year 11. We've been constantly surprised at just how little homework they get, and have been waiting for it to be ramped up each year, but if anything, he gets less now than in year 7. Some teachers just set homework as finishing off any class work they didn't have time to finish, or revision for tests (for those teachers who do regular "end of topic" tests every few weeks).

A few teachers set a lot of homework, but that seems to be more a matter of poor teaching, i.e. lack of planning meaning they run behind and the kids have to "teach themselves" topics there's no class time for, or lack of discipline meaning work which could have been done in class wasn't due to disruption etc. This isn't subject-specific, it's teacher specific, i.e. he has a crap history teacher at the moment so is basically teaching himself, whereas last year, they had a brilliant history teacher who set virtually no homework as he was properly planned and got through it all in class. Likewise his current Physics teacher is doing no end of topic tests, whereas last year his Physics teacher did a topical test every 2/3 weeks.

Not normal as a general rule. I do like the idea of them revising as they go. I always advise that to avoid cramming later but less than 25% listen to that advice.

It's more common in our more conscientious y11s from March until their exams though. Some in the spring of y11 will have built up to quite heavy timetables.

I used to do a bir more than that (more like 4 hours a day and up to six a day at the weekend) and nearly had a nervous breakdown in Yr 10, moved schools for 6th Form to less pressured environment which saved me (though my health never seems to have recovered totally). So if they want to achieve sever mental health problems they’re going the right way about it.

I tell all my Yr 11s and Yr 13s to ramp it up over the year, rather then risk burn out by trying to maintain a big workload over the whole year. In my view that’s more appropriate for exam term in Year 11 or for Year 13s, probably appropriate most of the time (as they get fewer taught hours).

No, not usual, and if they're expecting it from the start of Y10 then their kids will be burned out by the time the exams roll around.

If the kids are in school 5 hours of lessons plus half hour form time per day, then that's 27.5 hours work at school, plus the work in the evenings would give a 52.5 hour week. Way more than is sustainable.

The teaching must be very ineffective in that school. That workload would be tedious and crushing.

Son in Y10 in private school. Between an hour and a half and two hours a day. Possibly four hours one day at the weekend.

The workload above is not feasible.

What age is that? We were asked to do three hours a night at a NI grammar school decades ago, only from 15/16 up though.

DS2 (Y11, state school) is doing about half that, so about 10-15 hours per week. He has been consistently putting in those hours every week since Y10 (including in the school holidays), and seems to be doing OK.

My DD in year 10 does nowhere near that much. She works in class, so the sort of homework that involves finishing what they started in class doesn't take her long. She's also pretty quick at maths, so rarely needs as long as the School thinks they should take. I'd estimate she does 4 hours per week maximum at the moment, and leaves most of it to do on Sunday afternoons.

My dd (Yr11) doesn't do that much.
My dd is my 3rd child to do GCSEs.
She does a lot more school work than either of her older siblings did at this age.
to be fair, she often stays at school and does a study period or goes to get some help from someone, and will, on many nights to 3 hours, but then, on other nights she will only do one.
Weekends I doubt if she will do more than 3 hours over the whole weekend.
As I say, she's doing far more than either her brother or sister did at that age.
There's no way that is "average" or even usual, IME.

It is like that in private schools. It is very tiring for the children.

My son is in year 10 in Sept. So I'm just marking my place and would be interested what people say
