I think Petitpois is raising a very important point here.
Ultimately the cut off scores aren't just about kids results - it also is about how many children on the same score as your child or higher selected your first choice grammar school as their first choice grammar school. And then of course distance comes into the equation.
Now we've had all sorts of discussions here over the years - which grammar is best academically, which is best for sports, is co-ed or single sex best, is there a bias against some schools from some areas in Birmingham (or nearby), etc....
But the point is that once scores are known very personal decisions on how to rank school choices comes into play and that decision believe it or not can be based on where siblings are at, where friends are likely to be going, where you work (i.e. it's easier to drop off/ collect your child at x school than it will be for y school), logistics of the commute, etc....
I've even known parents who felt their child had only just made the cut off (or was a late wait list offer) and therefore would struggle at the grammar so opted to stick with the local comprehensives where they would remain top of the class.
There are so many decisions (and I have to say some families will include the child's opinion in all of this - I very definitely had a little fish in 2013 for starting in 2014 who had absolutely no interest in a 1 hour commute to school if it would mean less sports time after school. It influenced our decision against putting Handsworth Girls down as a choice although it was viable. We were in absolutely no doubt that it was a great school - but we had a kid in tears saying she didn't want to go there all by herself on a regular bus (actually 2) on her own. Papatrout was also very concerned about it - as little fish looked about 8 years old when she was 11. I was voted down 2 to 1 for putting it on the CAF and the rest is history).
So - yes kids came along and took the 11+- but each child & their family will have different opinions on which school is 1st choice, etc... based on a myriad of reasons and genuinely there is no predicting that.
Know that all of these grammar schools are excellent.
Know that all of them will be over-subscribed.
But know that each year which school is most popular or whether co-ed is preferable to single sex will be some of many many reasons why parents put schools down as 1st choice, etc....
We also know that there will be some families who may take the 11+ but actually will ultimately go private (my view is this is great news because it will free more places in state grammars!).
I'm so sorry that this isn't straightforward where once results are out you definitely know one way or the other - but there are benefits to this:
1) it delays the anxiety now until the spring (you can put this to the back of your mind and get on with life).
2) it keeps hope alive. If your borderline there is always hope - it's worth taking the chance really (at least in Birmingham) where we have 6 choices on our CAF.
3) it allows your child to focus on Year 6 and things Year 6 - which they deserve.
Enjoy Year 6 with your child. Soon Year 7 will roll around and Mum and Dad hanging about the school gate won't be so welcome. I sometimes feel my kids only speak to me when they want spending money these days
