To have a fair comparison of school performance it is essential to measure how much each school "gives" to children rather than simply showing the crude end results. To do this, measures of standards on entering and leaving school would be equally essential, as would be a measure of a child's innate ability and the quality of the educational environment of the home and community.
Publication of raw results at seven, 11 and 14 gives no true measure of what a school has contributed to children's education. For example, a secondary school admitting children at 11-plus, of whom 90 per cent are "good" achievers, would rightly be expected to achieve at least 90 per cent "good results" at GCSE.
We need to find a system measuring the true value of what a school "gives" to its children.
Given a level playing field, the vast majority of schools will strive to perform and compete. The uneven playing field of raw results that we have at present may give comfort to some schools, but many, many more will feel demoralised by the unfairness of the comparisons.
We need to lift morale and lift teaching standards, not to denigrate on false evidence.
