I should imagine so, Okanagan, yes. Tennis age groups in this country are worked out by calendar year rather than school year, but they also shift those age groups twice a year rather than once so those who are old in their year group in the spring will be young in the autumn, for example, and vice versa.

There are even more fluid ways of addressing the problem, though. For example, in New Zealand rugby is grouped according to size rather than age so you don't put off keen small boys who get fed up with being flattened :D

The specific story that prompted my post was this one:

The study referred to is here:

There's an interesting (slightly older) survey on age/attainment generally here (the section on special needs diagnosis is particularly horrifying):

I'm with ginx on this one.

DS1 is a July baby, place at KES in September and predicted 6B in maths. He is mature for his age and but is also very, very determined. The extra learning he did for his 11+ (and in fact throughout primary school) has given him confidence to push his ability that much further despite the age difference.

DS2 is a June baby, quieter but he is finding his confidence and doing well at school. He is in the top groups and will also try for the 11+ if that is what he wants to do.

How much is about ours and others attitude towards our children, and how much is about general perception of the age difference?

However, I know this isn't the original point of the discussion and if it can be used to help an appeals tribunal then go for it!

Bloomers151, I'm glad it isn't only me who had a child born in summer who is doing very well. My dd2 is also mature for her age, and always has been.

But she's always been mature. My dd1 born in July isn't mature, confident or academic. She is more like dc a year younger than her (but of course, they aren't a year younger than her - some of them are just a couple of months younger).

It's just the way they are.

Maybe my May born daughter is something of an exception :)

I think that all of the data will be up soon, but here is the last three years for SGGS

2011
Sept/Oct/Nov births 24
June/July/August births 16

2012
Sept/Oct/Nov births 26
June/July/August births 16

2013
Sept/Oct/Nov births 35
June/July/August births 28

I believe that it is likely that more older children actually took the test than younger ones, but I do not have this data.

Here it is. The figures haven't been reported accurately where the number was 5 or less. Also the reported totals may not be accurate as they appear to simply reflect the PAN for the year, and may not be the actual admissions numbers.

No offence, but the data (and research) shows what the data shows.

Individual anecdotes about how well one's own summer-born child is doing does not render the statistical data or numerous studies incorrect.
