Flawed measure of performance
https://www.tes.com/magazine/archive/flawed-measure-performance
I appreciate the need to move from crude measures of attainment value-added measures. But CVA is based not simply on a pupil’s progress, but also ethnic make-up, deprivation and gender balance. Yet these factors are mostly the same for pupils on intake as at the end of their time in school.
And CVA misses a crucial factor in a school’s context, namely funding per pupil of which there is a huge variation.
The statistical basis on which CVA is predicated is also flawed. I assume that there is hard evidence to justify including ethnicity and gender as significant factors in a school’s context.
I do not understand how the same can be true for deprivation: given that a pupil may be entitled to free school meals in Year 7 but no longer by Year 11, or vice versa, CVA also implies that we as a nation have lower expectations of ethnic minority and poor children and boys.
