It's been known for years that the oldest children in class perform better in school than their youngest classmates. But according to a new study co-authored by University of Toronto Scarborough economist Elizabeth Dhuey, that gap can persist, with older children more likely to attend post-secondary school and graduate from an elite university.

"Older children, in this case those born in early September, do better in elementary school than their younger peers," says Dhuey, whose past research has explored this phenomenon.

"What we found in this study is that gap persists throughout their school careers, so they end up being more likely to attend a post-secondary school and graduate from an elite university."

The study, by Dhuey, an associate professor of economics, and a team of three economists from U.S.-based universities, was published by the National Bureau of Economic Research. It followed differences between Florida children born just before and after the Sept. 1 cut-off date to start kindergarten. (In Ontario, the cut-off date to start kindergarten is Jan. 1.)

    Alternatively: People are learning before they go to school. The ones that arrive with a 10-month head start over others don't lose it. I'd be interested to see how this advantage correlates with socioeconomic index, because I'd imagine that richer parents spend more time with their children doing things that give them an advantage when they start school. I was one of the youngest in my class, but I started to read when I was 3 and do basic arithmetic (add, subtract, multiply, and divide) by the time I was 5. A lot of children at the school where my mother taught in a poorer area started school aged 5 expecting to start learning these things then.

    Hm,... might this be post-hoc theorizing? My first reaction was to challenge the study. This question pops up from time to time and IIRC the long-term effect has been debunked in the past. TLDR, so I cannot judge the quality of the study, but to follow children to adulthood is extremely challenging and the data is subject to all of confounding, selection bias, and measurement error, implying that unless properly taken into account, study results could but reflect those phenomena.
