ABSTRACT When placed into age groups for junior sporting competition, the relative differences in age between children leads to a bias in who is evaluated as being talented. While the impact of this relative age effect (RAE) is clear, until now there has been no evidence to show how to reduce it. The aim of this study was to determine whether the selection bias associated with the RAE could be reduced. Talent scouts from an elite football club watched junior games and ranked players on the… 

Leveling the Playing Field: A New Proposed Method to Address Relative Age- and Maturity-Related Bias in Soccer

A reduction in RAE may lead to fewer dropouts and thus a larger player pool, which benefits, in turn, talent identification, selection, and development.

Relative age and maturation selection biases in academy football

Professional football academies need to recognise relative age and maturation as independent constructs that exist and operate independently and separate strategies should be designed to address the respective selection biases, to better identify, retain and develop players.

Relative Age Effect in Elite German Soccer: Influence of Gender and Competition Level

The data show an RAE in female and male German adult soccer, which could be accompanied by a loss of valuable elite players during the youth phase of the career, Consequently, the pool of talented players at the adult level would be limited.

Leveling the Playing Field: A New Proposed Method to Address Relative Age- and Maturity-Related Bias in UK Male Academy Soccer Players

Relative age selection bias persists within all major soccer leagues and youth soccer academies across the globe, with the relative age effect (RAE) being typically characterized as the over

The relative age effect is larger in Italian soccer top-level youth categories and smaller in Serie A

A strongly biased selection emerged among elite soccer players competing in Italian championships, highlighting how young individuals born in the first three months have many more chances to become elite players compared to the others.

Talent Selection Based on Sport-Specific Tasks Is Affected by the Relative Age Effects among Adolescent Handball Players

The findings provide support to the hypothesis that the selection process exacerbates RAEs even when using only sport-specific selection criteria, and an advanced maturity and/or an above-average body size increases the selection odds for relatively younger players.

Evidence for the Relative Age Effect in the Spanish Professional Soccer League

It is concluded that the relative age effect is consistent and exists throughout Spanish soccer, whether at youth or professional levels, while in clubs the effect continued to be significantly present in all cases investigated.

A tale of two selection biases: The independent effects of relative age and biological maturity on player selection in the Football Association of Ireland's national talent pathway

This study investigated the associations between biological maturation status (classified using the Khamis–Roche method for the percentage of predicted adult height at the time of observation) and

Relative age effects in Elite Chinese soccer players: Implications of the ‘one-child’ policy

Results showed a clear and obvious RAE for all age groups with the observed birthdate distributions for each age group significantly different from expected distributions (p<0.05), and noticed a differential RAE according to the players’ position on the field as reflected in different effect sizes.

The Beginning of Senior Career in Team Sport Is Affected by Relative Age Effect

Data highlighted a bias in the selection of senior teams, which may limit the chance to identify talented players born late in the second part of the year, which should be promoted by Italian sport federations by equally promoting the joining of young players to senior teams.

Initial identification & selection bias versus the eventual confirmation of talent: evidence for the benefits of a rocky road?

Examination of identification and conversion rates for academy rugby players in a major English rugby academy demonstrated a reversal of the RAE “benefit”, whereby late-birth players were less likely to be selected, but more likely to achieve senior professional status.

A change in the structure of youth involvement in soccer is proposed to reduce the impact of the RAE on talent identification and selection, emphasizing the robust nature of this phenomenon.

The influence of relative age on success and dropout in male soccer players

Results indicated that youth players born from August to October (the early part of the selection year), beginning in the 6–8 year age group, are more likely to be identified as talented and to be exposed to higher levels of coaching, and to become involved professionally.

It is argued that this grounded cognition has the potential to influence coaches’ selection decisions and in turn account for RAE as coaches are biased towards physically more matured players, even when no apparent performance advantage is evident.
