Success and failure seem to be entrenched in the two education authorities at either end of this year's primary school tables.
A league based on pupils' performance in their Sats tests at the end of primary school is headed by Richmond upon Thames - home to royal parks and English rugby.
Bringing up the rear is the inner London borough of Hackney.
Both have been in those places for three years in a row.
This year, Richmond got even better, with its schools' average score in the test in English, maths and science rising five points to 267 out of a possible 300.
Hackney got worse, dropping one point from 210 to 209, the same as four years ago.
In a statement, the learning trust which runs education in Hackney said the results were in line with expectations.
It was pleased that its schools' average value added score - showing how pupils have improved during their primary school years - had gone up and was in line with the national figure.
Of the 150 LEAs, 108 had better scores this year; 15 had the same as last year and 27 got worse.
The biggest improvement was in Medway, Kent, from 218 to 230, a rise of 12.
The biggest fall was seven points, in Harrow, north-west London, down from 254 to 247.
An analysis, using the same methodology the Department for Education and Skills employs for the "most improved" schools, highlights the areas which have improved in each of the past four years.
On this reckoning, 54 of the main 148 LEAs - just over a third - managed sustained progress.
At the top was Poole in Dorset, up 18 from 225 in 2002 to 243 this year.
But 12 LEAs had worse results this year than four years ago.
In four of them the difference was six points, the worst being Stoke-on-Trent, down from 226 to 220.
