Academisation has no long-term effect on GCSE results, research suggests
Converting struggling schools into sponsored academies may improve GCSE results initially but appears to have no long-term effect on attainment, according to research by the London School of Economics in partnership with the Education Policy Institute. They found GCSE grades rose in the years before and after conversion. After that, however, GCSE performance dropped back and continued to fall over the next three years until improvement was “back to zero” by the fourth year of being an academy. Earlier this year, analysis by the LGA found that 86 per cent of local authority schools were rated good or outstanding by Ofsted, compared with 82 per cent of academies and 79 per cent of free schools.

Note- GCSE results from Hampshire schools (where 86% are now good or better) look good this year- but with the new criteria, it’s rather difficult to be precise at the moment.
Congratulations to all children at our non selective comprehensive schools across the county who have achieved so much!
