The primary objective of this paper is to propose a conceptual checklist to assess crisis communication efforts during pandemics and in their aftermath. No consolidated checklist exists for assessing the effectiveness of crisis communication at all levels during pandemics. A literature review was conducted, encompassing articles on crisis communication during SARS, swine flu, H1N1, ZIKA, Ebola, and/or COVID-19. Based on the review, a comprehensive checklist was developed to enable researchers and evaluators to assess and review all important aspects of crisis communication during pandemics. The final Assessment tool for Crisis Communication during Pandemics (ACCP) consists of 30 criteria. Further research is suggested to validate the checklist. The global COVID-19 pandemic is a crisis of unprecedented proportions. The crisis arrived in full view, yet it caught everyone off guard: politicians, hospital administrators, pundits, business owners, and the general population (Boin, Ekengren, & Rhinard, 2020). What distinguishes a pandemic from other crises are its characteristics as a "long wave event" (McInnes & Hornmoen, 2018). Where crises such as a major fire or airplane crash are over within a few hours or days, COVID-19 is, at the time of writing, an ongoing crisis that has generated widespread socioeconomic impact. Insight into how governments, citizens, businesses, and media have communicated during the pandemic may help to improve our learning from this crisis and support preparation for future pandemics. Countries on all continents have placed their citizens under various forms of lockdown during COVID-19, implementing measures from the obligation to wear face masks and maintain distance from others, to quarantines and school closures. Similar to earlier pandemics (Abraham, 2011), the initial need is for clear communication on what the public needs to do to reduce transmission as well as treatment advice. Everywhere, crisis communication is used as a public health intervention to inform and advise the public on necessary measures to minimize the impact of the COVID-19 pandemic. But as COVID-19 progresses around the world, communication efforts are also needed in terms of citizens' resilience, (national) public leadership, and in communicating with stakeholders whose businesses are closed or suffering from lockdown situations. At the same time, we have observed public leaders around the world who did not agree with the measures proposed by experts. US President Trump and Brazilian president Bolsonaro are examples of public leaders who consistently underplayed the messaging of experts with regard to social distancing and the wearing of face masks,
