This doctoral work investigated the socialisation of PE specialism graduates (PESGs) as generalist teachers with expertise in PE. Teacher development was examined from a variety of perspectives, including PESGs’ self-efficacy to teach PE; the influence of PESGs’ prior experiences on their understanding of quality PE; the organisational socialisation of PESGs through a micropolitical lens; and the influence of an online community of practice on PESGs’ development as teachers and leaders of PE.

Having worked closely with primary school teachers, Cillian's teaching interests are centred upon preparing student teachers to apply their skills within their complex teaching landscapes.
