Interesting statistics on success and birth month

I came across this when analysing data the other day. It shows that at the end of year 6 71% of pupils born in September achieve the expected standard in writing, reading and maths but only 58% of children born in August achieve the same. It goes down gradually from Sep.

I knew this pattern existed but seeing it so clearly in data was quite a shock and also very interesting. It says to me that clearly the education system isn't working for our summer borns. I believe this trend balances out but when? GCSE? Degree level? Or will it always have an impact? Wondered your thoughts.

Nope it is never equal but i guess the gap gets slightly smaller.
Setting/streaming makes it worse.
I think some get left behind and it is usually the youngest. As sept born are still top at end of ks2 this then affects gcses because they are set sometimes in yr 7 based on sats.
Targets for gcses are also based on sats results so summer borns may get lower targets. Teacher pay is based on them achieving the targets so more help would be given to help the ones with higher targets.
