Because of the way that erm the school changed over from having a system of streaming in its first three years, to a system where mixed ability was introduced year by year from the first to the third year, I was able to follow two groups of pupils through the school one lot of pupils in their streamed classes, and then another lot following them on in their mixed ability classes and try and discover something about the differences in their experience of school in the two different modes, in the streamed and in the mixed ability classes.
