Early childhood education and care (ECEC) had sustained benefits for young children’s vocabulary, communication, problem solving, and personal-social development during COVID-19, particularly for those from socioeconomically disadvantaged backgrounds.

Early childhood education and care (ECEC) settings faced significant disruption during the COVID-19 pandemic, compromising the continuity, stability, and quality of provision. Two and half years on from the first UK lockdown as pandemic-era preschoolers enter formal schooling, families, practitioners, and policymakers are concerned about the impact of the disruption on children’s cognitive and socioemotional development, especially those from socioeconomically disadvantaged backgrounds. Using parent-report data from 171 children aged between 5 and 23 months in Spring 2020 (M=15 months) living in the UK, we investigate whether previously attested positive associations between ECEC attendance and the development of language and executive functions was maintained as early years settings navigated operational challenges over the first full year of the pandemic. In response to concerns about school readiness, we analyse the relationship between ECEC attendance and children’s communication, problem-solving, and personal-social development. ECEC was associated with greater growth in receptive vocabulary over the 12-month period, regardless of children’s socioeconomic background. ECEC was also associated with greater growth in expressive vocabulary, but only in children from less advantaged backgrounds. Our data suggest a similarly positive association between ECEC attendance and the communication and problem-solving skills of children from lower socioeconomic (SES) backgrounds, and between ECEC and the personal-social development of all children. We found no effect of SES or ECEC attendance on growth of either of our measures of executive function. Overall, results suggest that ECEC had sustained learning benefits for young children growing up during the pandemic despite ongoing disruption to settings, and also had specific benefits for children from less affluent home environments. As children progress to primary school, we discuss the importance of adjusting the expectations placed on pandemic-era children, and adapting curricula and learning conditions to enable schools and families to make the most of learning opportunities.
