The month in which we are born affects our experience of and progress through the education system and is known as the relative age effect. This study reports on a project in which the author conducted mixed methods research into the impact of different birth months on enrolment patterns and participant experiences within further education in England, a neglected sector for this research area. This paper challenges the current view that the negative impact of being born later in an academic year cohort dissipates with age. Analysis of the findings shows that enrolment patterns are skewed towards the summer months for those entering the further education college in the study and that the month of May should be included in the definition of summer months. Summer-born study participants were aware of their relative age at a social and physical level, but made no connection to their academic progress. This paper argues that relative age is a significant driver for enrolment to and, therefore, subsequent performance within further education, which should be monitored alongside other better known disadvantage factors, with the aim to reduce and eliminate this systemic disadvantage.
