Study shows oldest kids in class perform better

Children who start school at an older age do better than their younger classmates and have better chances of attending college and graduating from an elite institution, a new study from the National Bureau of Economic Research in Massachusetts has found.

The study focused on the differences between Florida children born just before and after the September 1 cut-off date for starting kindergarten, which means the youngest children in any class were born in August and the oldest in September of the previous year.

David Figlio, an economist at Northwestern University, together with the study co-authors found that on average demographically similar September-born children performed better than their younger August-born classmates, throughout their academic careers.

The age a child starts school may also affect college attendance and graduation rates.

Among families in the middle socioeconomic group, the older, September-born kids were 2.6 percentage points more likely to attend college and 2.6 percentage points more likely to graduate from an elite university.

On the downside, August-born children were 1 percentage point more likely to be incarcerated for juvenile crime, the study showed.

These are not "massive differences," but they are "meaningful," said Figlio.

The most surprising finding for Figlio and his co-authors was that the gap between August-born and September-born children occurs at all socioeconomic levels and is not easily closed, even in high-income families.

They compared the performance of August-born and September-born children in the same families based on Florida birth and education data and found that even in high-income families, there was a gap in achievement between children who started school at a young age and siblings who started when they were older.

There's no clear remedy to the problem, Figlio warned.
