In the OECD's annual study of educational performance, the Programme for International Student Assessment (PISA), girls score better in reading in all countries even at primary level, and much better by the time they are 15.
Consider three other countries renowned for their educational performance: Singapore, South Korea and Finland.
It is not far-fetched to imagine that children who have a couple of weeks of happy holidays might return to school as more contented and committed students, with implications for both educational performance and the risks of antisocial or criminal behaviour.
Relying on the literature on educational systems, we assumed that educational systems broadly differ in their degree of differentiation, their level of standardization, and the availability of resources and that these system features are significant for the educational performance of migrant children.
But the effect of moderately differentiated education system on education performance is more positive (although not significant) than that of a comprehensive education system (16 points), and that runs partly against the first hypothesis that any differentiation in educational systems is detrimental for the educational performance of migrant children.
4 UNESCO has applied comparative tests in several of the region's countries, and it is [End Page 220] precisely in the context of the UNESCO laboratory that some of the systems for measuring educational performance in Latin America have been developed.
How do they account for the educational performance in their state back in the good old days before the Common Core?

In summary, the bottom chart shows that family background trumps what people continue to regard as "natural" ability in accounting for children's educational performance over time.
Public scrutiny achieved what legislation could not.There have been many other such successes in areas as diverse as restaurant sanitation, car safety, nutrition, home loans for minorities and educational performance, note Archon Fung, Mary Graham and David Weil of the Transparency Policy Project at Harvard's Kennedy School of Government in their book "Full Disclosure".
