In recent times, Ireland's post-primary schools have experienced considerable social, cultural, economic and technological change. As a result newly qualified teachers are entering an increasingly diverse and rapidly changing school environment. Studies indicate a diversity gap between the profile of pupils, and of teachers in post-primary schools; whereby a homogenous population of teachers, teach a heterogeneous population of students. Consequently, efforts have been made to better understand the diversity, and profile, of those entering the post-primary teaching profession. This paper contributes to this body of knowledge, through an investigation of the profile of entrants to concurrent (post-primary) initial teacher education programmes (ITE) in Ireland 2009-2020. Previous studies have investigated the profile, and diversity, of entrants to consecutive (post-primary) ITE, while less is known about the profile and diversity of entrants to concurrent (post-primary) ITE programmes. Data from the Higher Education Authority is used to compile a profile of entrants to concurrent (post-primary) ITE in Ireland from 2009 to 2020. The results indicate that these entrants have a more diverse profile than entrants to concurrent (primary) and consecutive (post-primary) ITE. This paper finds, therefore, that concurrent (post-primary) ITE, contributes to the overall diversity of the teaching profession in Ireland.
