DS (Year 7) has just had a report with Y9 target levels on.... which all seem fine, btw, I'm not concerned, and he is on or above target in all subjects so there doesn't seem to be anything to worry about.
However, is there a 'standard' way of extrapolating from these targets to likely target GCSEs? I know that it will all depend on progress over the intervening years, but I would find it useful to have some idea.
