Time Out or Fast Break? The Relative Age Effect in NCAA Division I Basketball.

The current investigation examined the impact of academic timing and the relative age effect (RAE) in men's and women's intercollegiate basketball. Academic timing is particularly important in the context of intercollegiate sport, and has received very little attention since Glamser and Marciani (1992) introduced the topic in this journal more than two decades ago. When a student's actual athletic eligibility year is consistent with her or his anticipated athletic eligibility year (based on year of birth), she or he is classified as 'on-time.' Those whose actual athletic eligibility years coincide with a younger age cohort are categorized as 'delayed.' The birthdates of 475 female and 429 male National Collegiate Athletic Association (NCAA) Division I basketball players were collected from the rosters of top-ranked teams and identified as either on-time or delayed based on their birth date and eligibility status. Chi-square goodness of fits tests (X²) were used to compare the distribution of birthdates for the female and male student-athletes with that expected within the United States across each quartile. The analyses revealed that on-time student-athletes were more commonly born in the early months of the selection year whereas delayed student-athletes were more likely to be born in the latter months. Our results suggest that on-time student-athletes born late in the selection year are disadvantaged and that delaying entrance to university may be an option for equalizing the playing field and/or gaining an advantage.
