Verbal bias
Posted: Mon Mar 10, 2008 10:24 pm
Hi, My DD had a score of 216, 10 away from the passmark. That put her 193 and on the waiting list.
What really gets me is that there appears to be a bias towards the Non Verbal paper as opposed to the Verbal. I don't dispute the scores, just the way they are weighted. 51/75 in the Non verbal, 68% and 76/90 in the verbal, 84%, standardised scores of 103 and 113 respectively.
You don't have to be Stephen Hawking to work out that there is an unequal weighting applied to the Non Verbal paper. There is age to take into account of course but this is surely attributed to each part of the exam equally.
I think that given a proper equal rating her score would be nearer 229 than 216.
If there are any other Redbridge parents willing to publish their chlld's results and their standardised scores, I could prove or disprove my theory.
If there were enough of us we might be able to do something.
Does anyone know the formula that Redbridge use?
