The table below shows the 150 local authorities ranked on the basis of their schools' achievements in the proportion of students getting the equivalent of at least five GCSEs at grades A*-C in 2004, using two measures:

NEW: the benchmark the government is introducing, which requires two of the five to be actual GCSEs in English and in maths
The final column shows the difference between the two.
