var123 However there are lots of reasons not to let them do it:-
Some interesting points. However:
1. What would it do to their self-confidence if they didn't get the top grade?
How will this be any different to dealing with their self-confidence if they didn??t get the top grade when sitting it with their peers?
The outcome could be the same whether they sit it earlier or later. However, by not sitting it earlier could result in period of real boredom which can reduce their enjoyment and passion for the subject area resulting in a reluctance to carry it on to a higher level.
If the outcome was not the desired or top mark it could also suggest that the early prep. challenged them more than they were ready for so over challenging them?
If you are suggesting that waiting to do the exam with their peers would more likely result in the highest mark, then surely this would suggest that, in fact, the child did not actually need to be challenged further?
To give an example:
I was subjected to a 10 minute rant from a parent with a DS at a local private prep. She was fuming that the school had refused to put her DS in for his maths GCSE. She entered him for it herself and paid a tutor for two hours a week and "he did really, really well and got a D so he was obviously ready for it".
2. How would they fill their time waiting for the A level courses to start?
Why would they have to wait, surely they could move directly on to it?
3. No way would I want them to go to university early (I did it and you miss out on some social stuff, which you'll never have a chance to experience again. My uni photo ID had "Not 18 until ..." stamped on it, which I found highly embarrassing.)
Why would they have to go to university early. Why could they not look at other additional GCSEs or A levels (unless they had a fairly narrow subject interest range). Bear in mind state secondary schools vary in terms of the number of GCSEs that students take.
I have school friends who did 5 A levels (and got top grades in all of them).
They could do iGCSEs (assuming they are not already) or IB
4. Its more cohesive to just take exams at the same time as every one else in your year group.
This is one way to look at it. However, I see it as more challenging. If a child spends a year focusing on 1 GCSE, they will find it far easier than focusing on 10-14 GCSE at the same time. What??s more the pressure of sitting 1 GCSE exam on one day will be significantly less than sitting 10-14 GCSE exams over a period of a few weeks.
5. Neither child likes to stand out.
Which would surely reinforce the argument for not awarding higher than a level 6, surely?
6. The criticism that I'd face for having hot-housed or failure to let them enjoy their youth or something equally ignorant of what's actually going on.
You don??t strike me as putting your own hurt feelings above the best academic interests of the children TBH.
My own concern about a child sitting such important exams as GCSEs and A levels early is their level of emotional maturity in dealing with the stress etc. However, I have the same concern over a child always being pushed to the very top end of their ability range. Children need to be able to focus on the boring easy task as much as the harder, more challenging task if they are going to be prepared for adult life.
