A former independent school teacher writing under the pseudonym Timothy Hine has written in the Daily Telegraph of his disagreeable six months teaching in a comprehensive.
It came as something of a shock to him to discover that state schools are not at liberty to choose which pupils to teach: so they do get, amazingly, quite a few children who are - shock! horror! - quite tricky to teach! Who even require discipline! Who do not have ambitious parents hovering in the background!
For the first time in his life this man had to put some effort into his teaching. Naturally, he bombed and naturally he blamed the state system for his failure, and not his own teaching; naturally it did not occur to him how absurd is the national sychophancy towards schools that decide every year which pupils they feel like teaching...then smugly scoop the top rewards in the league tables.
