ABSTRACT
That was more or less the reasoning portrayed in press accounts earlier this month of a report stating that differences in the performance of the best and worst schools increased as children got older. Of course they do. It would be astonishing if it were otherwise.The older,bigger or cleverer you get, the more space there is to be different.A 16-year-old with serious learning difficulties may well be performing like an 8-year-old. It is pretty hard to be eight years below average at the age of 7.
