It sounds like some schools manage it well, and others sound appalling.
It's ridiculous to narrow down the curriculum and get rid of the arts subjects, even if it's only temporary. It's happening more and more throughout education. My children do music outside of school (at our expense) but a lot don't and I know that the weekly (or more) singing lessons were enjoyed by them all as a class. Completely knocked aside. A bit of singing would probably do them all a lot of good! Ditto painting / drawing etc.
My son is quite academic (like his older brother who went through this 2 years ago) and should do ok (for what it's worth!) but he's bored to tears and I'm sure there must be a horrible stressed atmosphere in his class. Goodness knows what it's doing to the ones who struggle, who are anxious, who have additional needs ....
His teacher is one of the Deputy Heads so she's out of the class 1.5 days a week anyway, and they're left with TAs who - in this school - are, some of them, barely literate themselves. Apparently since Easter she's been away more, and has just left practice tests for the kids to do with the TAs overseeing them. So they're not learning, just testing. They've also taken down the partition between the 2 Year 6 classes to make one big class, so the TAs can patrol all 60 of them. Practically day in / day out. This is the 3rd week they've been doing this. Although it's been a gradual build-up since about this time last year.
I really am not clear on whether the results stay on a child's report forever or not. I'm pretty sure at the secondary school DS is going to, they don't take too much notice as it's a selective school anyway (Grammar) and they're pretty hot on doing their own assessments. I don't know about other schools in the area though (the kids from DS's primary disperse in the direction of at least 10 different secondaries) . I'm not impressed that the teacher keeps telling them the results will be used to predict their GCSE grades - the kids don't need this kind of pressure. And I'm not sure it's even true!
And the disruptive kid has been on a reign of terror since Reception. Really has made life miserable for the whole class, with lots of disturbance. And they finally remove him (don't know where - a cupboard somewhere?) just before the SATS. Not his fault he's disruptive either - clearly there are issues there that haven't been addressed.
When it's all over they will have some nice school trips (i remember from my other DS) but then they do a Year 6 production and that becomes a stressful headache too, with the teachers telling them they're rubbish and stressing them out.
It's all ridiculous. I just wish they could carry on learning in a normal way, right up until the last few days.
