The Influence of Relative Age Effect in the Assessment of High School Students in Physical Education in the United Kingdom

The common practice of annually age grouping children in education, likely done under the assumption of similarly aged children sharing similar abilities and learner characteristics, may actually undermine equity and fairness in student assessments. This strategy has received criticism for (dis) advantaging those older children born closer to the "cut off" date for entry into an academic year and for promoting the existence of relative age effects (RAEs). This paper explores the possibility that RAEs may be prevalent in the end-of-year attainment levels of junior high school physical education (PE) students. The PE end-of-year attainment scores were collected from 582 students in grades 7, 8 and 9 (aged 11-14 years) in the United Kingdom (UK). The results from a one-way analysis of variance (ANOVA) indicated a significant main effect for month of birth (p = 0.001) and gender (p = 0.001). Follow up interviews with heads of PE (HoPE) revealed a lack of awareness of RAEs and inconsiderate assessment strategies, which deviated from the requirements of the formal curriculum. The implications of RAEs in school PE assessment and possible recommendations are discussed.
