DDs just finished year 7 and hasn't done that well in her end of year exams so will be going from the top set to the mixed ability stream for all subjects except English and maths. These are streamed for separately as sets 1 to 3 and she is moving from 1 to 2. TBH I am a bit gutted as I have heard the behaviour and expectations are not as great but I can't do much about it. We always has dd down as a bright child but now I am wondering if that's not so much the case. I worry that she will get dragged into bad behaviour by the lower sets and it becomes a self fulfilling prophecy. In your experience, do the lower or middle sets tend to always end up with lower grades for gcses?
