On the headline measure this school is in the lower half of state-funded primaries in England.
Compared with the fifth of schools whose intake is second least disadvantaged, which is where this one sits, it is in the bottom quarter.
There are no progress measures for primary schools any more. They were calculated from a key stage 1 baseline, and statutory key stage 1 tests ended in 2023, so nothing has been published since. That makes attainment the only official measure — and attainment tracks intake closely, which is why the comparison against similar schools above is the more useful of the two lines.
