My in-laws have offered to pay school fees for my son. He hasn't started school yet, so this would be all the way from preschool intake. They also did this for their other grandchildren. A very kind and generous offer, but....
I have been comparing the possible schools. Our State catchment school has a pass rate of 20% of S5 leavers achieving 5 or more Highers (sort of eqivalent to 3 A levels in the English system). There are 2 nearby private schools - one is selective and helps 80% of its pupils achieve 5 Highers, whilst the other takes anyone who can pay and gets 50% of its pupils 5 Highers. It is costly. Both private school charge around £10k a year - so we're talking about £120k for the whole thing in today's money.
My observation is that the private schools don't seem great. The State school can't select, so if you compare its results with the non-selective private one, it doesn't do that much better. I mean, half of the pupils at the paying school still don't get 5 Highers. Also, the State school is taking pupils from all socio-economic backgrounds - whilst you'd expect pupils at the private school to be privileged in terms of parental income, parental education levels etc.
My feeling is (given DS already benefits from educated parents - a good predictor of exam success, lots of encouragement and stimulus) that he probably stands as good a chance of exam success at the State school, rather than the ropey looking private ones... and that people will be more inclined to think his exams are good if he achieved them at a State School.
Neither of the private schools make it into the Sutton report of the top 100 schools. The only one anywhere near to us that is mentioned has fees of £20k and is very elite.
So, I think he would be better off in the State system, even if it means a polite - thank you, but no - to the grandparents. AIBU?
