You report (TES, June 11) on a recent demonstration that increased spending in schools leads to better examination results when the social status of the pupils is accounted for. Please allow me to draw attention to my own finding, in February 1986, of precisely this result (University of Liverpool, Report FM11186). It was based on government data given in The TES (December 14, 1984).
I studied the percentage, in each of 36 "northern" local authorities, of pupils gaining one or more A-level passes, as this varied with the percentage of the population in the high socio-economic groups and as a function of the annual teaching expenditure per pupil. This clearly showed the large effect of funding in the socially poorer authorities. My correlation was good enough to show that 61 per cent of these authorities had results that lay within 10 per cent of the correlated norm; 86 per cent lay within 20 per cent.
