So. Farewell then Progress 8 – FFT Education Datalab
Much has been written over the years, including by ourselves, about how Progress 8 favours schools serving intakes with particular characteristics (and conversely how it works against others). For this reason we have long advocated for a contextualised Progress 8 measure to be published alongside Progress 8 and Attainment 8. But it will become apparent next year that Progress 8 is far fairer to schools serving disadvantaged intakes than raw attainment measures that do not take account of prior attainment. […] The picture is clear: the relationship between disadvantage and outcomes is far stronger for A8 than for P8. Put another way, the least disadvantaged schools will be even more likely to be ranked highly based on A8 compared to P8.
