Good lord, you're a bit *****ly.
edit: Not a sweary a pointy, thorny thingy
It is obvious that hot-housing a child through reception can gain results, but to what end? Reception has a strong focus on socialisation, play and getting a grounding in literacy and numeracy. Yes, most functioning adults can read and write well enough to coerce a 5 year old into exceeding KPIs.
That in no way proves that home schooling is a superior method of teaching. My point, which you ignored, was that it was arrogant to assume a single individual or couple can provide a complete and broad education to suit the child over the longterm and to believe so is arrogant (on their part, you note I was talking about homeschooling parents, I have no idea if you are one or not and neither do I care). Ancient Greek is not really part of the curriculum during reception, or any of the other subjects I mentioned, so clearly my focus was on the longterm benefit, or in my view the likely negatives.
