My DC moved home last Summer and started a new primary in September, one in KS1 and one in KS2. I read the Ofsted report after I visited the school and I thought the report's conclusion was not as good as the school merited. Even at Christmas, I still thought that the school had been short-changed. But now two terms in, I can see that the inspector described it perfectly.
She worked out exactly what was good and what was bad about the school in one day whereas it has taken me seven months. I am v. impressed! (and maybe a bit disappointed too!)
