I don’t know why people think new grammar school will bring down the standard of all the existing comprehensive school. A good school is really depending on the SLT, teachers and the resource that school have. A few bright students leave, would this make the school fail? I don’t think so. The school will only fail if the SLT isn’t strong enough, the teachers couldn’t deliver the teaching.
The current school system in England is really not fair, children have a better education if their parents can afford a good school catchment house or private school fee.
In my old school days(not this country), the education is totally free, no private school exist. Everyone had to take exam at the end of primary school and junior high school( a common exam in the whole county) and according to the result, you apply to the school you want. So you have 2 chances to switch school(age 11 and 14). The school has rank, there are some very academic ones(like the grammar school here), normal ones and the career school. I think this system allows social mobility. When I went to University, I had classmates from all background. There are lots of bright students from poor family.
I went to a top boarding school in my county, the school actually didn’t have good facilities, as it was in a poor area and didn’t have enough funding. Most of my classmates were from less well family, they worked really hard. However, my school had always got the best exam results for university entry exam.
I visited a few secondary school in England when DS applied, I was so surprised to see the good facilities in every school, every school has the condition to provide a good education. However , the GCSE A*-C in our local school is only 40%-50%. Does the school not have the resource, of course it has. I think the true reason under the bad performance is the attitude. Lots of children don’t know education is important, they don’t care. The school is not strong enough to introduce good decipline.
