I've long since thought that a lot of the problems in school was that individual teachers did their own thing, which meant loss of quality, extra work for them, difficulties when kids move between classes etc.
Just noticed that our son's school have "standardised" their English Literature. Instead of individual teachers randomly chosing their own texts (from the exam board lists) to study, the head of dept has imposed her own texts on all the GCSE/A level teachers.
Not only that, she's imposed time frames in which each text is taught, i.e. they're all being taught a particular book each term.
This means that they can now "bulk" order the texts in larger numbers, so parents can get a better discounted price. It also facilitates the children being able to move up/down a set whereas in the past they were "trapped" for the entire 2 year period.
Despite the school historically getting very good results in Maths, Science and humanities, for some reason, English grades have always been a lot lower. They are hoping that standardisation will address this. We shall see in 2 years' time!
Personally, I'm a great believer in standardisation. I never could understand why teachers wanted to "do their own thing" all the time, which to my mind just makes more work for themselves.
