Peachy and Riven, I completely understand your distress.
FWIW in the story they were thinking about failing regular schools, not the 10% lowest acchievers in regular schools. That makes no excuses, I can't imagine deciding on that basis, or on any other basis which 10%. I truly hope that you are underestimating the oter parents at your DS's school, or it is a very sad state of affairs.
My DD goes to a school with a big SEN unit and I would never dream of considering that to be a deciding point on 10% of pupils, despite DD not being in that unit.
I think everyone will watch TW and think how something like the 10% would affect them personally, not just those parents with kids with additional needs and not just parents with kids in failing schools, all parents.
I hope, because it is difficult viewing, that there is some resolution to it tomorrow.
P.S. Can someone explain the face of Bo thing to me - I watch TW but not DW.
