Relative age effect
Relative age effect is the measurable advantage held by children born early in their school year over those born late in it.
Size and persistence
The oldest children in a year group outperform the youngest on average, and the gap narrows but does not fully close through primary school. It shows up in attainment, in sports selection and in referrals for additional support.
It is one of the most robust findings in education research and one of the least acted upon.
