Do Private Schools Give Better Educational Outcomes? What the Evidence Shows

The raw outcome gap

Private school pupils (those attending fee-paying independent schools) significantly outperform state school peers on A-level grades, Oxbridge acceptance rates and access to professional occupations. Around 7% of UK pupils attend private schools but they have historically accounted for around 40-50% of Oxford and Cambridge undergraduates and over half of the most senior judges, journalists and politicians.

The selection effect

A significant portion of the private school premium is explained by selection: private school pupils come from families with significantly higher incomes, parental education levels and expectations. When researchers use statistical methods to control for socioeconomic background, the academic value-added of private schooling is substantially reduced — though some residual advantage remains.

Where the advantage is real

The genuine private school advantages that have the most evidence: smaller class sizes and greater individual attention (particularly in the early secondary years); broader extracurricular provision; and the network effects of attending schools that have alumni in positions of institutional influence. This last factor — what researchers call "social capital" — is difficult to quantify but appears in research on labour market outcomes to be a significant mechanism of advantage transmission.

The policy context

The Labour government that came to power in July 2024 committed to removing the VAT exemption on private school fees — a tax change worth around £1.6 billion per year, which independent school bodies argued would force fee increases and potentially closures, while proponents argued it would fund improvements in the state sector. The implementation and effects of this policy will be closely watched.
