Independent school pupils gain extra two years by 16, research
Attending an independent school in England is associated with the equivalent of two additional years of schooling by the age of 16, research revealed.
The February 2016 ‘academic value added’ report by the Centre for Evaluation and Monitoring (CEM) at Durham University looked at the differences in attainment between pupils educated in independent and state schools from junior or prep school through to GCSE, controlling for differences such as prior ability, socioeconomic status and gender.
The research revealed:
- Independent schooling accounts for a 0.64 of a GCSE grade increase.
- At GCSE independent schools have higher average scores in all subjects;
– Greatest differences are found in French, history and geography.
– Smallest increases are found in chemistry, physics and biology.
- If independent schools were measured on international PISA outcomes, they would outperform the best European nations and be level with Japan and South Korea.
- Independent education is favourable academically at ages four, eight, ten and 16.
