ds1 had a fabulous time at primary and we worried that secondary couldn't possibly be better.
But it has been! The teaching has been superb and he is just blossoming and academically he is just flying.
In particular there are some teachers where the quality of their marking is superb, they clearly put a huge amount of effort into differentiating the work appropriately (ds1 is taught entirely in mixed ability classes), and they also motivate/inspire the pupils, so ds1 is keen and enthusiastic to get on and complete his homework to the highest possible ability.
If I were to write in to school and particularly mention these staff (History, MFL, Science, Maths and the Librarian) then it kind-of implies his other teachers aren't much cop. And they are. They're all superb, it's just these ones are even more superb!
