I also found it interesting that the school clearly thought things were more or less OK. They seemed to believe there were improvements that could be made here and there but they were mostly on track. Ofsted appears to agree, having rated it "good." Not very high standards!
I remember visiting four primary schools when my eldest was coming up to Reception age. In each one, I was given a whistle-stop tour of all the classes. I know that is only a snapshot but... At the moment I poked my head in, few of the children seemed to be engaged in learning. In three of the four schools, out of all the children in all the classes, I would estimate about 20% appeared to be listening to a lesson or doing something constructive at the moment I saw them. (And that is just giving the appearance of doing something constructive; when I was that age I listened quietly and worked dutifully but little of what I was doing engaged me in the slightest. So I wouldn't say those 20% were all necessarily learning much.) The other 80% were staring into space, or getting up to mischief, or waiting while the teacher told someone off or handed out materials or checked work. It must have been soul-destroying for those kids, to spend most of their time just waiting.
The fourth school was much better, so that's where I sent my dd five years later when she wanted to try school. She didn't report much disruptive behaviour in the classroom there. Nevertheless, she said that she learned about the same amount in a day at school as she'd absorbed through autonomous education in a day at home, and school left her with virtually no time to see friends or pursue hobbies. So she came out again, convinced that even a very good school didn't hold a candle to home ed.
