    With all the caveats applied about P8 only being an estimate for any current cohort, because the estimates table comes from the previous cohort’s exam results, it is beneficial to have some idea of the P8 score for a cohort along with other measures of progress and attainment.

    With the changes to points allocations for grades moving from 1-8 for all subjects to 1-9 for English & Maths and 1-8.5 for unreformed GCSEs, this renders the 2015 estimates table unusable as the values are calculated on 1-8 points for a grade.

    Have you any thoughts on dealing with this? We want to move our calculations to the 1-8.5 system to give a reflection of what our A8 and P8 scores will be for this Y11 cohort (rather than perhaps roll back the points to continue using the previous points methodology.)

      Hi Andy, better statistical brains than me recommend that we only use P8/A8 calculations to look for relative differences between subject and pupil groups in a school. Until the next set of A8 estimates are released (later this year?) the 2015 averages are all we have. Maybe some readers of this blog would like to comment?
