"That is not to say that I agree with this. I understand exactly what you mean reallytired when you say that you think hard working children should deserve a place in top set. However, moving a lazy bright child into set 2 does not make them 'up their game', they just shrug, turn off even more from education, and can end up becoming really problematic by the time they hit Y9/Y10 and puberty, as the level of challenge is simply not high enough for them."
I am confused by your post. You are right in saying that children are grouped by attainment rather than effort.
Imagine you have two children child A has a score of 96 in CATS and scores 7C in a science test in year 8. Child B has a score of 133 in CATs and scores 4C in the same science test. Would you honestly put child B in the top science set in place of child A? Would you honestly deny a clearly capable child the opporuntity to do triple science because they messed up their CATS test?
Doing well at school is about far more than raw intelligence. A lot of subjects like Science or Maths build on prior knowledge. Putting a child who is 4C in the top set would be setting them up for failure as they do not have the prior knowledge to progress. If raw intelligence was enough then there would be no need to send children to school or for anyone to do any work.
Personally I think "learning pathways" are vile. Its grammar school selection with a new fancy name. I rejected a school that had "learning pathways" set on the first day of year 7. Children were put in path ways on the basis of one test. If my son had gone to that particular school he would have been the denied the opportunity to do triple science.
Recently he has been congratulated as he got the second highest score in his year of 180 inspite of a medicore CATs result. The same science teacher complains about ds' total lack of home work yet praises him for effor. Bizare.
I am glad that my son's school does not introduce learning pathways until year 9 when they have actually got to know the children and decisions are made in consulation with the parents. This school also has the highest results in the area.
