It's a list of 100 education academics who have signed a letter against league tables. I should (but probably won't) do some digging, but I imagine that has to constitute a significant chunk of our academics who are working in education. It would be interesting to know how many of our education academics are pro-league tables.
This though, should give any politician cause to pause. They might not be perfect all the time, but at the very least you should listen to the experts, the people who dedicate lives to figuring out how things work rather than just steam rolling ahead with your own version of "common sense". Not that I expect that this will give anyone in the current government will take note. Or if they do it will be to write it off as a disgruntled minority.
