The common practice of placing children into age groups for sport may acutely benefit those who are more developed physically, emotionally, and cognitively . However, those who are born in the later stages of the year appear to experience an unintentional bias in their long-term sporting success . In accordance to this, it is important that coaches are aware of a ‘Relative Age Effect’, where being born at a certain time of the year holds a distinct advantage in sport and academic success. In other words, those born later in the year appear to be at a disadvantage because they are typically physically, emotionally and cognitively less developed than other children.
