St Mary's and St John's CofE School’s letter
Its own results against England’s schools, not the town’s School Grade.
How school letters are worked out
Each school’s measure is compared with every graded school in England of the same phase: for primaries, the share of pupils meeting the expected standard in reading, writing and maths (DfE’s three-year average); for secondaries, Attainment 8 and the share with grade 5 or above in English and maths, each turned into a z-score against England’s schools and averaged. The letter comes from the share of those schools it beats, in the same bands as every grade on the site. The same method gives U.S. schools their letters, against their own state.
Graded: England’s open mainstream state schools with published results (grammar schools included, which select by test). Not graded: special schools, alternative provision, nurseries, 16–19 colleges, UTCs and studio schools, Welsh schools. Ofsted plays no part.
