Good job you mentioned those as I should have used them. They suggest that it’s not just a hiccup in the data etc
Do you happen to have graphs of those already?
I think it also suggests we can take a largely positivist approach in that these are actual real teachers and not a construct from the data and also that we ought to be able to find them. What has occured to me that’s even more worrying is that the 12 might not even be full time….
