During the COVID-19 pandemic, German early childhood education and care (ECEC) institutions had to limit their provision of ECEC, implement protective measures, and handle new organizational tasks. Data from two longitudinal surveys (October 2020 to July 2021) among ECEC managers and pedagogical staff were analysed. Limited staff resources, limited access, and high pandemic-related challenges (i.e. difficulties and conflicts related to implementing protective measures), were negatively associated with the frequency of pedagogical practices (Models 1, 2). Manager ratings suggested increased developmental needs for children with low socio-economic status; also higher frequency of pedagogical practices at early stages of the pandemic (T1) was associated with lower increase of developmental needs at a later stage (T2, about 5 months later). In sum, this contribution provides evidence about how the COVID-19 pandemic might have affected quality in ECEC provision on both the structural and interaction level and how this, subsequently, impacted child outcomes.
