Alderbrook vs Henry Cavendish SW12 Balham

[morticia69]

In a dilemma about schools in Balham area of London. Have a choice between Alderbrook and Henry Cavendish - the schools are not very far apart. Spoke to a parent of a child at Alderbrook who said that there have been lots of changes recently, some not for the better. However, their early years got a 2 from Ofsted. Whereas henry cavendish got a 3 but i've heard quite positive feedback about the rest of the school.
Anyone know either of these schools who could give me a bit more info.
