Exactly this. I thought this was obvious to everyone but there are some people who think the reason that so many more students get A’s at private school is because they are remarkably better than state schools. They’re confusing cause and correlation.
More students get A’s who come out of private schools because the intake of students who go to private schools is very different to those who go to state schools for the 3 main reasons of socioeconomic factors, parental input and the heritability element of intelligence. A student who goes to a private school is more likely to come from a background with money, parental input, parents who value education highly and talk about it in a positive light, parents who were most likely educated themselves, less anti-social behaviour at home, surrounded by peers who also value education etc. These kids would most likely get A’s in the state school system anyway.
I'm sorry but this just isn't true.
Yes, the private schools have an intake who are higher achieving and better supported on the whole, and so the results are bound to be better, but if you think that's the whole story you're kidding yourself.
I went to a private secondary from 11-13, state from 13-16 and then also a state 6th form centre.
The difference in education between the secondaries was immense. The private school was better funded, class sizes were smaller, the facilities were better, it was much better resourced with enough equipment and of decent quality. The difference is sports, science, arts equipment and facilities was astronomical.
But the most important thing in my opinion was the expectations were higher. You were expected to achieve and were encouraged and supported to do so.
I learnt pretty much fuck all in the state school. I had a great time and learnt a lot of good life lessons but because I was bright I was allowed to coast. I wasn't pushed at all. I passed my GCSEs on what I learnt at the private school by age 13, pretty much.
The 6th form was great, that was an example of state education done well. It is possible. My state primary was excellent also.
But there are still loads of state secondaries that are failing kids, particularly bright kids.
The Tories have messed around with the state school sector and defunded it. Teaching in state schools is a hugely stressful job, every year the profession loses brilliant teachers who, understandably get out of the system as it's untenable. The schools are strapped for cash so often choose to employ loads of cheap NQTs instead of a balance that includes expensive teachers on higher pay bands. So experience is being drained from the profession.
You're absolutely kidding yourself if you think the only advantage private schools have is the intake.
The solution is to get rid of private schools of course, as then the state schools would be decent as the rich and powerful would care enough to invest decent money in schools, but that's not going to happen any time soon.
Despite the above, there are some great state secondaries. The are some dire ones also. More often, there are schools that will give your child an OK education, but won't get the kids achieving to the best of their abilities.
