Normally I'd agree with this for most kids but I'm not seeing it as 2 separate distinct thing..... GCSE's/ A Level, but more of a continuation.
My DD is very strong across the board, no weaknesses, probably strong enough to take A levels in almost anything, but this strength has a relative imbalance. She's been taking CAT4's throughout junior school, the NVR/ VR/ Quant/ Spatial battery in the autumn term, and PTE/ PTM in summer term. The teachers throughout have said there is no real difference between these scores and how she's performing in class.
STEM ability and future potential is probably best evaluated through Quant, Spatial and PTM. In the yrs 4, 5, 6 she's taken these 9 exams, 3 times 3, of a possible maximum of 141 times 9 = 1269 marks she has scored 1267. Dropped 2 marks.
So she's clearly immensely strong in STEM and this is the way she'll most likely move in the future. That said I haven't got any assurances whatsoever in her current school they acknowledge or will cater for her talent, no mentoring, and like I say to them if they can't recognise she has this talent then we as parents can't trust the school to develop it.
So we're stuck in a situation where we could be passive, hope she doesn't fall back into the average but if she does I can't go back to the school and say I was promised X and Y because I wasn't. Or I can be proactive and find her a school which recognises this talent and gives me assurances her level will be maintained and developed, perhaps at an accelerated pace.
Generally in light of what I say above I'm not really expecting any massive special attention, far from it, I just want comfort she's in the right school with the ability to spot her talent and means to develop it.
Now when it comes to GCSE's I could take the view she gets there, hopefully gets A/A*'s in STEM and then we take it from there. But in this case if if did occur how much ground has she lost in the meantime from 11-16? and will a lack of rigour and dedicated support throughout this period mean A levels are more of a leap?
The decision we've made is the proactive one. She has to move.
