I would absolutely support the return of grammar schools.
I have 1 DD who is G&T, she is currently left pretty much to her own devices at the local comprehensive.
The stats for this school show that high achieving students don't improve during their time there. The mid level (on entry) students improve a great deal and the low level (on entry) students improve the most. There is little incentive for teachers to push the high achievers because they have little bearing on the percentage of passes at GCSE/A Level. The teachers know they will get those C grades (5/6 in new money I think) without much work so they concentrate on the mid and low level achievers to bring up the grade average.
I would have liked her to have had the choice to sit the exam to go for Grammar School entry but we don't have any nearby. My other DC would benefit more from the comprehensive school as they are mid level achievers and this is what the local school is best at improving.
We live in a deprived area of the country. We have 1 high school (now an academy) which is deemed as 'requires improvement' and has been for years. It has never achieved more than 50% pass rate at GCSE grade A-C. Last year only 4 students, yes that is just 4 students, went to university (none were RG universities) from my DD's school. Only 37 students left that school last year with A Levels. Only 7 of those managed to get Apprenticeships. Is the current comprehensive school system helping these other students? I think not.
Our next closest high school (outstanding) is 8 miles away but currently there's no public transport during school open/close times to that school. The school bus does not pick up from our town. That school is in some ways selective itself. Its in an affluent area and it only takes the most affluent students from the deprived town who can afford to drive their children to school. Those students do considerably better than those students who attend the local high school.
I would love to see some investment in our town and I would love to see a grammar school open. The current school is failing a huge portion of students. Opening grammar schools mainly in deprived areas will definitely improve social mobility. I don't see why it wouldn't.
Deprived towns have low investment, poor housing stock, poor education standards, poor work opportunities. If you open a grammar school and bring up the educational standards then people/businesses will move to the area. They will demand more investment and improved work opportunities and the towns will improve. It wont happen straight away but it will eventually.
I don't think opening a new grammar school in an affluent MC area will be of much benefit but there's dozens of towns cross the UK that are deprived and underinvested and these areas are most in need of better education as they are more likely to have failing schools and low levels of attainment.
I hate to say it but on this subject I agree with Teresa May,
