My dd ended up in a particularly low stream in school based on the way the school said they grouped.
Where they had a large number of level 5 students, they took the raw scores from their SAT's results, used only the English reading element only (which they leveled at a 5c), removed the writing element because they say for several dd's they were teacher assessed so could not be relied on (note, this dropped her from a 5b therefore to a 5c), and for that reason also, did not use the science scores either.
Unfortunately, if all their figures are correct, this impacted my dd's position, as her writing score was much higher than her reading score.
Would this method in your opinion be totally reasonable?
Note, they do not use their own exams like other schools do, who do not trust primary schools SAT's results.
Thanks loads
