Data Caveat from the Department for Education:

We know from national data that pupils at junior schools, on average, have higher attainment scores at the end of key stage 2 than pupils at all other primary schools. However, on average, they also have lower progress scores. This may be for a variety of reasons and should be taken into account when comparing their results to schools which start educating their pupils from the beginning of key stage 1.
