The impact of Covid-19 is widely discussed, however, little is known about the actual changes in participants’ wellbeing before and during the pandemic. The current report provides a unique perspective on the differences in post-primary school leaders’ wellbeing one month before the pandemic outbreak (Time 1) and one year later (Time 2). The participants comprised of 267 (Time 1) and 251 (Time 2) post-primary school leaders whose wellbeing was assessed using Mental Health Continuum Short-form (personal wellbeing) and Workplace PERMA profiler (work-related wellbeing), as well as a one-question measure of perceived stress. The results showed that while leaders’ stress levels increased during the pandemic, their personal wellbeing remained the same, whereas many aspects of their work-related wellbeing increased during the pandemic, such as meaning for work, engagement or accomplishment. In addition to the wellbeing, participants were asked about their experiences of Covid-19, school community strengths, challenges, as well as their views about changes required to improve education in Ireland post-Covid. These changes included Communication, Assessment, Leaving Certificate and Junior Cycle reforms. The findings are discussed in the context of international research and recommendations are made across various levels impacting school communities in Ireland.
