Summer born children - it's their age that counts

Some studies have shown that children who are born at the end of the academic year (summer born children) tend to have lower educational attainment than children born at the start of the academic year. The differences might be because of the precise age when they take a test, because they started school at an earlier age, because they have had less schooling, or because they are the youngest in the class. A new report from the UK's Institute for Fiscal Studies finds that it is the age at which children take the test that is the most important factor. The authors suggest that UK national test scores could be adjusted to allow for this variation. However, this would not help to resolve the other problems that summer born children may face, for example, they are more likely to engage in risky behavior, such as underage smoking. Reassuringly, the authors point out that, in adulthood, many of the differences disappear, and summer born individuals are just as healthy, happy, and earn as much as their older peers.

On the same subject, a recent Centre for Longitudinal Studies working paper uses data from the UK's Millennium Cohort Study to examine whether summer born students are differently represented in ability groups in early primary school. Across all types of ability grouping (within-year, within-class), the author found a pronounced and consistent tendency for relatively older students in a school year to be placed in the highest group.
