During the COVID19 crisis, school closure was a frequent feature of Government responses. "The Children's School Lives" (CSL) national cohort study of primary schooling in Ireland had to be adapted and transferred online as an interim response to the unprecedented impact that the pandemic had on the research environment. Adapting longitudinal qualitative research in response to a global pandemic brought specific challenges. In addition to moving data collection to remote methods, longitudinal studies also needed to maintain a focus on retention of research participants and sustain an analysis that informs the longitudinal design of the study. Based on reflective research practice during the COVID19 pandemic and through the collaborative production of methodological knowledge, this paper contributes to the literature on remote research during times of crisis. However, it also extends this literature as the methodological learning can be applied beyond the very particular circumstances of a pandemic.
