The Birthday Effect: Firm Cut-off Age for School Admission May Impose a Lifetime Disadvantage

Educational program design would likely not be controversial if children were interchangeable parts, if they were like components on a factory assembly line.  In that case, different children could be placed in the same seat every year and have  a predictable and consistent outcome.  Traditional educational models seem to be predicated on the assembly line model. Children are expected to bend to the system; the system does not accommodate the individual.  One area where inflexibility has apparently resulted in measurable harm is in age cut-offs for kindergarten admission. Longitudinal studies show that younger students, as a group, perform more poorly on achievement assessments than their older classmates.  Called the  ‘birthday effect’, a strict age cut-off policy results in a kind of age lottery. Winners of the lottery are rewarded with lifetime benefits, benefits that are evident in areas outside the academic sphere.

study out of England, for example, demonstrates the disadvantage suffered by younger children in early school years and in their later academic careers.  Members of the younger group are less likely to attend university than their older peers; if they do go to a university, it is likely that they will matriculate at a low-tier institution. The age cut-off in England is fixed firmly at September 1, which is the beginning of the school year.  Consequently, the youngest children in a grade are those born in August. Called ‘August children’, these students statistically perform more poorly than their older classmates in tests that look at academic achievement and ‘happiness’.

There are educators who do not find these study results persuasive. The former Chief Inspector of Schools, Sir Chris Woodhead, for example, believes it would be wrong to make all children”‘comfortable”.  In commenting on the  findings about firm age cut-offs, Sir Woodhead declared, “If kids are always completely confident and comfortable, they aren’t going to make much progress.”

A debate about the ‘birthday effect’ has been examined by systems outside of England.  Norway, for example, also has a firm cut-off age for school admission. In a paper presented at Harvard University in 2004, Bjarne Strøm, a researcher from the Norwegian University of Technology and Science, discusses the birthday effect on 16 and 17 year-old students.  Professor Strom provides a detailed analysis of how early disadvantage endures throughout the academic careers of the younger student.  Professor Strom concludes, “These results suggest that more flexible enrollment rules should be considered to equalize the opportunities of the children”.

Yet another study, cited on NeuroNet, addresses the impact of the ‘birthday effect’  on grade retention. This study demonstrates that the youngest children in a kindergarten class are five times more likely than their older peers to be held back in a grade. The experience of being retained in grade can have a devastating effect on the child’s psyche and future achievement.

Advocates for student discontent aside (i.e., Sir Woodhead), a growing body of research indicates that rigid adherence to age cut-offs is likely not in the best interest of children. Studies suggest that children should be evaluated, individually, for school readiness.  While this may not suit a structured, one-size-fits-all educational model, it may suit very nicely the student for whom the educational system is presumed to exist.
