This has been asked so many times before.
Broadly speaking, on a wide level looking at millions of children, typically the privately educated do better than the state educated. However, many many state educated children do better than many privately educated children.
Yes, you can only choose the value and costs for yourself. You need to compare the private school YOUR child would attend with the state school THEY would attend and see how different those particular 2 schools are.
You have to decide what the ‘cost’ of the benefit is. This depends on how much the fees will mean in terms of life sacrifices for you firstly. If the fees are a drop in the o Dan and very affordable with no imaoct, the ‘cost’ is low to you. This makes it more ‘affordable’. If however the fees mean you can’t have holidays, or you worry about your boiler breaking down, the ‘cost’ is much higher for you. If you’re in the latter group and the orivate school is only slightly better than the state school available to your child, then the cost of choosing orivate becomes astronomical, in terms of the cost to you and the very limited gain.
If you are loaded and the state school where you live is truly dire and the independent is the best intbhe country, then the ‘value’ is high. Firstly it is very affordable, but also the ‘gain’ of private compared to state in this case is huge.
Most people don’t know the answers to these questions fully. They often can’t judge actually how much better the private school might be. They struggle to find ways to measure it accurately. Many don’t actually know many facts about the local options at all, but instead work in a prejudiced about state schools or private schools that might not be borne out in their locality. They also struggle to think fully about the longer term implications of fees….how rapidly they actually rise, ir the jump at secondary level, ir forget about factoring in impact on pension payments, retirement etc too.
For most people, private education is a luxury good and it’s not affordable and even if it can be stretched to isn’t good value. That’s because their income isn’t sufficiently high to make the fees unnoticeable, and also because many orivate schools are not substantially better than their local state schools. They might be better, but the small amount if gain is extortionately expensive in terms of the cost and true impact on most families, apart from those who are terrifically wealthy.
