These days and specially in Spain, we have been defending the right to choose a single-sex education in every country as it has better outcomes for lots of pupils.
Well, the Organisation for Economic Co-operation and Development (OECD) has published a study comparing the reading skills of teenagers against the levels of social equity.
In this study some countries do better than others, of course:
At the top end of the international spectrum, Shanghai, Finland, South Korea, Canada, Japan, Hong Kong and the Netherlands are among a select group of school systems with very high results and high levels of fairness, where pupils can succeed regardless of background.
Russia, Spain, Croatia and the Czech Republic are relatively strong on equal opportunities, but have low performance.
Bulgaria, Turkey and Kyrgyzstan perform poorly on both equity and results.
The UK belongs to a group of countries, including France,
Germany and the United States, that are above average for results, but
have lower levels of equity.
When single-sex schools demonstrate they have great outcomes it is worth the funding from institutions so every family can get the best education and the right to choose it.
