What % of children pass the test?

[MumWith3Kids]

Where can I find the stats which tell me the number of pupils that passed the test in Redbridge? compared to the number that sat the test?
I'm trying to work out the likelyhood of my son passing.
Within his school he is around the top 10% for Maths and around top 30% for English, but then he's not in a top performing primary school.
Not sure if I'm just going a bit mad - trying to work this out!

Hi
The pass mark will be around 80% based on past experience, there are 120 places and around 800 children sit the test for each school (hence 240 places across both GS in Redbridge with total 1600 pupils sitting).

As my user name suggests, eldest DS passed previously, and its been a lot easier this time around, but I can sympathise with all of you first-timers!!
