My DD's school use Jesson data to predict outcomes at GCSE. Does anyone know how they calculate the score each child gets? I know they only use Yr6 SATs scores but I was wondering if it was the same points as you see on the dfes websire regarding points for levels - eg level3 21 points level 4 27 points and level 5 33 points. DD's best friends Mum was asking me as the school will not budge on her DD's GCSE banding and thinks it's been calculated wrong. I've looked at various sites and my brain hurts
