Initial Teacher Education (ITE) can be viewed as a formative space in professional teacher identity development. Practice plays a key role in shaping teacher identity, providing a window into the reality of school life, as well as nurturing professional autonomy. Due to the COVID-19 pandemic, school life shifted suddenly and unrecognisably in March 2020. This paper focuses on the experiences of preservice teachers on an ITE programme (post-primary) in one Irish University during the period of sudden school closures. The data show the transition to be problematic, underscored by a chaotic pivot to virtual communication and a destabilising of the structures that normally provide consistency. Yet it also presented opportunities and responsibilities. We explore Victor Turner's work to consider school placement as an 'in between' space for preservice teachers and to examine the extent to which sudden school closures heightened this sense of 'in betweenness'. We argue that the pandemic and its lifting out of pervasive and predictable social structures, gave rise to a period of 'anti-structure'. We view school closures as an example of anti-structure, which challenged preservice teachers' identity formation yet also gave rise to 'communitas' through experimentation with different modes of being and doing.
